Red River Compact Commission Fort Smith, Arkansas

We have audited the accompanying statement of cash receipts and disbursements of the Red River Compact Commission for the period July 1, 1997 through June 30, 1998. The financial statement is the responsibility of the commission's management. Our responsibility is to express an opinion on this financial statement based on our audit.

We conducted an audit in accordance wrth generally accepted auditing standards for cash basis statements. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by the management, as well as evaluating the overall financial statement presentation. We believe that out audit provides a reasonable basis for our opinion.

The commission's policy is to prepare its financial statements on the basis of cash receipts and disbursements; consequently, certain revenue and related assets are recognized when received rather than when earned, and certain expenses are recognized when paid rather than when the obligation is incurred. Accordingly, the accompanying financial statement is not intended to present results of operations in conformity with generally accepted accounting principles.

In our opinion, the financial statement referred to above presents fairly, in all material respects, the recorded cash transactions of the Red River Compact Commission for the period ended June 30, 1998, on the basis of accounting described in the preceding paragraph.

Legislation impacting the Compact area passed during the 1999 session included the creation of the Ouchita River Commission and Ouachita River Trust Fund; establishing the "Sparta Aquifer Critical Ground Water Counties

Page 21 Remediation Act allowing creation of a county-wide board to provide water to substitute for Sparta Aquifer water; and general interest legislation allowing irrigation, drainage, watershed, regional water distribution and conservation districts to participate in watershed or basin studies. Commissioner Young updated the Commission regarding the status of the Memorandum of Agreement between the ASWCC and federal and state agencies for the state's mitigation banking program. He noted irrigation projects in the critical areas in Eastern Arkansas, and he reviewed the Nonpoint Source Pollution Program. Commissioner Young concluded his report stating the ASWCC had completed the state's Unified Watershed Assessment and identified seven watersheds as Category 1 waters in Arkansas. (Attachment "5")

B. Oklahoma - Commissioner Duane Smith presented the state's report on behalf of the Oklahoma Commissioners. He distributed a written report, and highlighted areas of interest. The Oklahoma Water Resources Board (OWRB) administers a $3 million program for Weather Modification for statewide hail suppression and rainfall enhancement. The program is funded through legislative appropriation and voluntary assessment of insurance companies. The OWRB also administers an extensive financial assistance program that awards loans and grants for the construction and improvement of water and sewer facilities. Since the beginning of the program, the Board has loaned over $600 million dollars, and in the Red River Compact Area, $107 million in loan program funds, almost $10.4 million in emergency grants and almost $4.6 million in Rural Economic Action Program (REAP) grants. Commissioner Smith noted items pending in the current Legislative Session including funding for the state's Beneficial Use Monitoring Program, implementation of regulation of poultry and swine industry created by the 1998 Legislation Session, and activities surrounding the resolution of the Sardis Lake lawsuit and creation of a regional water supply. (Attachment "6")

C. Texas - Mr. Don Neal, representing Jeff Saitas presented the Texas Commissioner's report. He distributed a written report and noted items of interest. Senate Bill 1, a comprehensive water bill enacted by the Texas Legislature in 1997, made sweeping changes related to the development and management of water resources in the state. The Texas Water Development Board and four state agencies were challenged to work cooperatively to formulate sixteen planning regions. Once each region has developed a water development plan, regulatory agencies cannot approve projects unless included in the plan. The legislation also required water rights holders to develop water conservation plans, and wholesale and retail public water suppliers are required to develop drought contingency plans. The TWDB was instructed to develop water availability models for surface water in all river basins in Texas with the exception of the Rio Grande. Interbasin transfer was affected by SB1, and the TWDB modified rules to accommodate that change; data coordination was enhanced, and the agency also implemented other associated rules changes. Mr. Neal also noted three significant items before the current Texas Legislature: Red River Boundary Compact, a measure mandating the permitting of a reservoir in the Brazos basin, and providing for the modeling of the Rio Grande. Mr. Neal also mentioned the Texas Weather Modification Program. (Attachment "7")

D. Louisiana - Mr. Ed Preau, representing Curtis Patterson, said the Louisiana Department of Transportation has once again been reorganized. He said Mr. Patterson is now the Assistant Secretary of the Office of Public Works and Intermodal Transportation, which is an appointed position. He explained there is a new Secretary, Dr. Kam K. Movassaght. Mr. Preau distributed a written report and highlighted items of interest. In response to declining water levels in the Sparta Aquifer, the Louisiana Legislature is currently considering a bill authorizing the creation of multi-parish groundwater conservation districts throughout the state, composed of major water users who would police themselves in conserving groundwater. He reported the

Page 22 Red River Navigation project is approximately 90% complete, approximately $103 million has been spent on port development, and the latest tonnage figures for 1998 were in excess of 627,000 tons shipped from public ports. He also noted the Mississippi River Levee project, involving a lawsuit over land rights. (Attachment "8").

VIII. REPORT OF COMMITTEES

A. Budget Committee, - Mr. Mike Mathis, chair of the Committee, reviewed the proposed budget with the Commissioners. He said the Committee recommended the two-year budget be approved as there were no changes. He noted there might be a need to increase the treasurer's bond. The FY2000 assessment for each state is set at $550. There were no other issues. Commissioner Duane Smith moved to approve the FY2000-2001 Budget, and Commissioner J. Randy Young seconded. The Budget Committee report was unanimously accepted. (Attachment "9")

B. Legal Committee - Mr. Dean Couch, chair of the Committee, stated he had a handwritten report that had not been reviewed by the Committee members, and he asked for a short break to confer with the members. Commissioner Fergeson called for a five-minute break. Following the break, Mr. Couch presented the committee report saying the legal committee met on the afternoon of May 3, and he introduced the members. He said the members reviewed a draft committee report and made some changes and modifications and the revised report was distributed to the Commissioners. There were two issues assigned to the committee: (1) draft proposed revisions to the Commission's rules concerning the election of a chairman, and (2) continue the assignment of developing an institutional history involving the allocation of water in the north quarter of the Red River system. Mr. Couch stated the first issue stemmed from a long-standing situation that the Commission faces virtually every year. The Commission is to have appointed to it a non-voting chairman representing the federat government. To address the problem (of no confirmed appointment of a chairman), there was proposed to be an Acting Chairman, and in essence created the position of a Vice Chairman — one of two commissioners of the host state — under rules for internal organization acts as chairman. The Commission asked the committee to look at the provision in the rules of the Compact that indicates that the failure of the President to appoint a federal commissioner will not prevent the operation or effect of the Compact and the eight representatives of the eight signatory states will elect a chairman for the Commission. The Legal Committee reviewed the provision and for next year suggested that through rule change, if the Commission so desired, another option other than the Vice Chairman acting as Chair would be that in the absence of a Presidentially-appointed chairman, the Commission elect a chair. The proposed rule as drafted within the Legai Committee report distributed, is to amend rule 2.2 and 2.3 (specified on page 2 of the report) with underlined language to be added, that would on essence allow the election of a chair. The language allows that if the appointed person attends the meeting, he/she would chair the meeting. The election of a chair would only be for the instances when the President has not appointed a chair, or where an appointment is made but has not been confirmed by the U.S. Senate, and the appointee is reluctant to attend. Mr. Couch said the Commission's current rules provide that unless waived there is a requirement that proposed rules be circulated at least thirty days prior to a meeting, and this proposal had not been developed and circulated to meet that provision. He said that if the Commission chose to adopt the proposal today, there would need to be a separate waiver included in the motion to adopt.

Page 23 Commissioner Fergeson asked the Committee's recommendation on who would be elected as Chair. Mr. Couch responded that in essence the Commission has always wanted and enjoyed the connection it has with the Corps of Engineers with its authorities and involvement in projects that cross all four state lines. The Commander of the Lower Mississippi Valley Division is typically chosen and recommended for Presidential appointment, and in fact the Commission rule indicates that when there is a permanent change of commander, "the Vice Chairman shall immediately request the President to appointment the new Commander"/ The internal rule triggers the request but there have been delays in completing the process. Mr. Couch said the Legal Committee did not make a recommendation for an elected chair pro temp. Commissioner Young said it was his recollection there had always been reluctance on the part of the LMVD Commander to come to the meeting until all "i's dotted and ts crossed." He asked that if under the proposed rule the Commission elected the Commander as the Chairman Pro Temp would that solve the concern of his not coming. Col. Robert Crear, representing Major General Phillip Anderson, stated the Commander did not attend today's meeting because of a conflict in another Commission meeting. He said that in his capacity, he fulfills all responsibilities of the job, even without confirmation. Commissioner Theis said a problem arose several years ago in the designation of the Federal Chairman because the Justice Department ruled that a Commissioned Officer in the Corps of Engineers would be subject to losing his pension if he took the job as Federal Chairman of the Compact. There was argument then about what it actually meant and whether some benefits would be at risk. Since that time, there has been little trouble getting approval, but it does take some time, and the Commission has had the rotating vice chairman from each state serve in the absence of the approval of the Federal Chairman-designee. He said he did not have any problem with the proposal, whether he be called Vice Chairman acting as the Chairman, or President Pro Temp in the absence of the regular chairman. Commissioner Fergeson said the only reason to have an elected chairman from within the Commission would be to have a chairman that would actually be knowledgeable. Commissioner Theis responded the advantage of having the Federal Chair from LMVD is to enlist the Corps of Engineers' support in program activities, information, and helpful in deciding engineering issues and federal construction within the basin, even though the Federal Chairman is not a voting member. That also allowed the other Commissioners to be on equal footing. Chairman Fergeson asked if there was a motion to waive notification and adopt the proposal. Commissioner Theis asked if adopting the proposal would be an election of a President Pro Temp that would serve in the absence of a Federal Chairman in lieu of the vice-chairman arrangement. Mr. Couch clarified the current rule about the vice chairman for the Host State next year acting as chair for the meeting is not proposed for deletion, but the proposal would add another option for an elected chairman that may or may not be a Commission member. Commissioner Smith stated for clarification, that if the Federal Chairman attends he is the Chair. If the Federal Chairman doesn't attend, the Commission has the option of electing someone else. If the Commission does not elect someone else, then the vice-chairman would serve as chair. Mr. Couch said the rules specifies a vice chair shall be elected at the annual meeting from the Commissioners of the Host State for the next year. There would be an election of the vice-chairman, and the proposal also creates the possibility to elect someone else not from the Host State. Commissioner Smith asked if the rule could state, "from the Host State" and then the Commissioners from the Host State would decide who would serve as chair. Commissioner Young stated he believed that is what is current, and adding that language would be an unnecessary complication. Commissioner Fergeson said it was his

Page 24 recollection the Commission has asked the Legal Committee to propose a way where the Federal Chairman would feel comfortable about attending. Commissioner Theis responded that there is no problem to ask the Federal Chairman to attend and to Chair the meeting, but he would be reluctant to add language that would allow the Commission to appoint a President Pro Temp from outside the four states. Following additional discussion among members of the Legal Committee, Commissioners and others, no action was taken by the Commission on the recommendation by the Legal Committee on Assignment #1.

Mr. Couch said the second assignment to the Legal Committee was the continued development of an official history involving the allocation of water on the North Fork of the Red River system. This matter has been presented in various forms over the years to the Commission, beginning with the internal rules to compute the apportionment rule for the Compact, which is divided into four reaches and subbasins. The Engineering Committee began drafting those in the early 1980s so there is some way to actually check the use of the waters for compact compliance. In drafting those rules, the engineers representing Oklahoma and Texas became stuck on a particular rule on the North Fork of the Red River and Sweetwater Creek and reported draft rules to the Commission. The Commission could not resolve the issue, and it has been bouncing back and forth between the committees and the Commission. Last year, there was information from the Lugert-Altus Irrigation District gathered by personnel involving negotiations of the Compact and there was a briefing about the issues that were being discussed and circulated to the Commissioners as a reminder. Mr, Couch said two major issues presented in the briefing paper appears as "Exhibit A" in the Legal Committee report. The two issues are: (1) How does the 60/40 allocation for Reach 1, Subbasin 1 apply to the North Fork Red River and Sweetwater Creek; and (2) Do the allocation provisions of the Compact control over water rights of the Lugert-Altus Irrigation District and others which existed prior to the effective date of the Compact? Mr. Couch said that after much discussion at the Legal Committee meeting, there are no further suggestions to this Commission which would be productive to resolve the issue. Ms. Atwood added that in discussions of what the Legal Committee might recommend, they found they were coming in full circle from earlier legal briefings prepared. She said it looked as if there would not be any agreement, and so a recommendation is not beneficial.

Commissioner Art Theis moved to accept the Legal Committee report, and Commissioner Duane Smith seconded. The report was unanimously accepted. (Attachment #10)

C. Engineering Committee - Mr. Mike Mathis, Chair of the Engineering Committee presented the Committee's written report. He said there were two assignments; the first to continue to track the status of the U.S.G.S. stream gaging program, specifically regarding potential impacts as a result of the Corps of Engineers' budget cuts. He explained that so far the cuts have been in the Tulsa District impacting the State of Oklahoma that has been working with the Tulsa District. The Tulsa District has pledged to review the cuts to lessen the severity of the impact. Oklahoma is looking at other options to increase state funding to cover the shortfall, as well as looking a private contractors as a potential option. The report contains a copy of the U.S.G.S. webpage depicting the status of the COE participation in Oklahoma. The Little Rock District is taking notice, and the Committee recommended continued monitoring of the situation. Mr. Mathis said the Committee discussed the second assignment concerning website development for the compact. He said it was decided that an Internet provider would need to be identified, as well as finding someone who could physically develop a website, at a fairly

Page 25 substantial capital investment He said the Oklahoma Water Resources Board has developed a website, and it possible to incorporate a webpage for the compact at the Board's site, at a low cost to the Commission. The Committee envisioned that the OWRB could establish links within the compact webpage to other compact states. The Committee recommended requesting the State of Oklahoma to develop some example web pages for consideration by the Engineering Committee and the Commission at its next annual meeting. Commissioner Art Theis moved to accept Oklahoma's offer to develop a webpage, and Commissioner J. Randy Young seconded. The motion was unanimously approved. Col. Robert Crear commented about budget cuts throughout the country. Commissioner Theis stated he did not believe the Compact should get into the stream gaging business. Chairman Fergeson asked for a motion to approve the Engineering Report and accept its recommendations, and Commissioner Theis so moved, Commissioner J. Randy Young seconded. There was no objection, and the report was unanimously adopted. (Attachment u11")

D. Environmental Advisory Committee There was no report by the Committee.

AMENDED AGENDA ITEM FOR DISCUSSION BY LUGERT-ALTUS IRRIGATION DISTRICT.

Commissioner Fergeson asked Ms. Donna Kirby, Manager of the Lugert-Altus Irrigation District, to address the Commission. Ms. Kirby addressed the members, and thanked them for amending the agenda. She said she had mailed the prepared history of Reach I, Subbasin I and had mailed it to each of the Commissioners, representatives of each states, the Corps of Engineers and the Bureau of Reclamation. In the packet, she explained, is information taken from the minutes of the all the compact meetings, summarized in her own words. Ms. Kirby stated she had compiled all the information from the meetings and Legal and Engineering Committees into two boxes and ring binders and is available for copying. She said she did not mail the attachments as they are quite thick; one copy has been provided to each state, and copies are available at the meeting. Ms. Kirby stated that Mr. Jim Barnett, attorney representing the District, will address the Commission. Mr. Barnett said that the Lugert-Altus Irrigation District (LAID) has been very concerned about the failure of the Commission to adopt rules and regulations pertaining to the North Fork and Sweetwater Creek. His said the District believed it is time to move forward as this is a very important issue to the District. Mr. Barnett explained his extensive background with this Commission, and during his time with the Legal Committee, he drafted the "Supplemental Interpretive Comments" and at that time the Committee's goal was to try to explain the nuances and "fuzzy wording" of the Compact. He said today he is asking the Commissioners to address two issues: (1) 60/40 allocation (as mentioned earlier), and (2) address the issue of federal withdrawal—does the compact adversely affect pre-existing federal interest? Mr. Barnett said he recommended the Commission adopt the approach already adopted on the other five main streams in Reach I, Subbasin I. He said there is no rational or legal basis for distinguishing between the five streams for which rules have been promulgated, and the two under discussion today, using the previous Engineering Committee work as a pattern. Mr. Barnett argued that the Compact lists the streams individually so that the 60/40 split is applied to each and every one of the streams, and not on an aggregate basis. He quoted from the Compact language, and supported his argument with discussion of legal briefings on the 60/40 rule. He said the Red River Authority of Texas had made application to the Texas Water Commission for a reservoir and the Commission's ALJ ruled against it because of the 60/40 split; however, he

Page 26 said his client's concern is that the application will come back as soon as next year, in the year 2000 the protections that are set out in the Compact in a later section go away and that is the real reason the 60/40 split needs to be resolved today and not postponed for another year. Mr. Barnett said he believed those in the Sweetwater Creek area that might be wishing to build a reservoir, and his clients, are entitled to know what the rule of law is going to be on how much water will be developed on Sweetwater Creek in order to maintain irrigation. Secondly, Mr. Barnett said he believed (the Supplemental Interpretive Comments) is a straightforward reading of the compact. Section 2.07 of the compact says that, "...nothing in this Compact shall be deemed to impair or effect the powers, rights or obligations of the United States, or those claiming under its authority in, over, and to water of the Red River Basin = He said it could not have been clearer that the compact would not impact any federal rights to water and those claiming pursuant to those federal rights to water in the Red River Basin. Mr. Barnett asked the Commission to recognize today by virtue of a rule the fact that any federal withdrawal of water, pursuant to law, prior to the compact being adopted, are protected. He suggested the Commission adopt the rule prior to any application for development on Sweetwater Creek because the purpose of the compact is to avoid litigation, and the interstate compact is the preferable means for resolving disputes. He said that the equitable apportionment of the waters between states is the desired resolution of interstate water disputes. Commissioner Fergeson asked if an alternative would be to extend the expiration date of the prohibitions. Mr. Barnett stated he did not believe the Commission could do that through the rules because it is in the Compact itself, and would require renegotiation of the Compact Commissioner Smith asked if other interstate compacts contain 60/40 splits on subbasin flow per stream. Mr. Barnett answered there is one subbasin where Arkansas has multiple tributaries across state lines into Louisiana some of which are named and some which not named, and to his knowledge rules have not be developed for that particular subbasin. Commissioner Young asked why regulations were not developed on these two streams when they were developed on the other five. Mr. Barnett said his recollection is that it was understood the stream was more controversial and even though there was development downstream in Oklahoma, agreement could not be reached on those streams at that time, and the assignment was made to the Committee to continue work on it Ms. Atwood interjected that Texas agreed to move forward, but that the accommodation would not have a legal effect. Mr. Barnett stated that he has worked with people interested in developing the Mangum project on the Salt Fork, expecting to develop 40 percent of the flow, and are counting on Texas not to put a dam on the stateline and take 100 percent of the flow. He said that under the theory that someone could espouse that all the streams could somehow be aggregated, that would make the Mangum project infeasible. Commissioner Smith asked if Texas= position is that it could take 100 percent of the flow on Sweetwater Creek and allow the 60/40 split on all of the water that comes to Oklahoma from the North Fork of the Red, essentially drying up Sweetwater Creek. Ms. Atwood answered Texas= position is that it is allowed to take 60 percent of the aggregate flow of the two streams together. Commissioner Smith stated, then, the amount of water in calculating the 60/40 split entirely comes from the North Fork, and none of it would come from Sweetwater Creek. Ms. Atwood stated she did not know the numbers of the flows on the streams to know if one or the other would dry up. Commissioner Smith asked if it was Texas= position from a philosophical standpoint, rather than a hydrological standpoint, that it could take all of the water from Sweetwater Creek and Ok!ahoma=s portion would come entirely from the North Fork? Ms. Atwood said she did not believe it could be stated that way, but that it is their position that Texas Is entitled to 60 percent of the two streams. Commissioner Smith said that in regard to any downstream state, the apportionment of water where one stream is dried up is unfair.

Page 27 Commissioner Smith then moved that rules to compute and enforce the compact compliance for Reach I Subbasin I be written for the North Fork of the Red and Sweetwater Creek on an individual basis exactly iike the other five named streams in the Subbasin, and have the Engineering and Legal Committees jointly prepare and circulate the proposed rules thirty days prior to the next meeting of the Commission. Commissioner Young seconded. Mr. Don Neal stated his concern the item was not on the agenda, that the District came to the meeting in an adversarial position, that no one had notice the matter would be voted on. He said the presentation is clearly from local interest, and Texas has no local interest present. He felt an item was inserted into the agenda at the last minute and there could have been notice and time to prepare. Commissioner Smith answered the issue has been in front of the Commission for a number of years. The Commission has heard from the Legal Committee it has no additional recommendation and that the Commission must decide. He said he believed it is appropriate for the Commission to decide, and the motion is simply to give direction to the Legal and Engineering Committee to write rules to be presented to the Commission for a vote at the next meeting. He said the vote would be for direction to the Committees. Mr. Neal answered a fundamental issue of due process is an equal opportunity to be heard. He said there had been plenty of time for the item to have been on the agenda if it were the intent of the State of Oklahoma and the District to decide this at this meeting. Because the Commission has been talking about it for years is not the same as setting it on the agenda for a vote. He said he was concerned about the precedence of how it was being done. Commissioner Theis said the item added to the agenda was not to vote on the division of waters of the Subbasin, but to add that the Lugert- Altus Water District could present the report. He said he did not have a problem with directing the Engineering Committee, and to bring it back to the Commission at the next meeting and for Texas to have a response and for Oklahoma to have a response. He said that is has always been said that if and when Oklahoma and Texas could arrive at a conclusion, then it could be voted on, but the Commission has always been reluctant that it would decide what Texas and Oklahoma could have and it has been a sticky issue. He commended the District for its development of the facts of the past 30 years saying there is enough information, it is just a matter of whether Texas and Oklahoma are ever going to come to a conclusion and decide what they want to do. He said it is awkward for Louisiana and Arkansas and that they ought to resolve the problem themselves. Commissioner Smith stated that while he is not an attorney, he did not see that there are any due process problems. The Commission would simply be giving direction to the Committees to draft something and then have an opportunity to vote at the next meeting. He added that he believed the two states should work out disagreements, but here there is a fundamental difference in that through the application of this type of language in the compact, any downstream state can be impacted and that warrants some consideration by the other states to enter the fray for a fair determination. Ms. Atwood stated this is a very complicated legal issue. To draft rules with only one decision is making the decision that is the way it is going to be. The only fair position would be to draft both positions. She added there has only been one characterization of the history presented, that Texas had not seen the document and is not confident that all the documents have been included. She said it is an issue that has not been settled since "day one= of the negotiations of the compact; there is no conflict and no theory of the compact is being violated and in that sense it is premature. She recommended that all the Commissioners be provided ail the legal briefings that have been prepared over the years before directing that draft rules be prepared. She said the motion brings up many legal issues and to pass rules that would impair Texas= water rightso r Oklahoma's water rights, will require a unanimous vote of the Commission. She said that [motion] could be extended and legal briefings could be done to even have the Committees draft rules that would require an unanimous vote.

Page 28 Mr. Neal stated that it seemed the Commission is setting a precedence of forcing a controversial issue without putting it on the agenda. Commissioner Fergeson said the motion is to ask two committees to draft rules. Mr. Neal said the rules are to favor one side. He asked if the Commission wanted to operate by adding controversial issues to the agenda and let one side line up their presenters, and then take a vote? Chairman Fergeson said that is not what the Commission is doing, that every year the Lugert-Altus Irrigation District has made a report and this is the first time he has heard the Legal Committee say there are the two positions and there is no place to go, and the motion to instruct the Legal and Engineering Committees to come up with a set of rules in a year from now is not underhanded. Ms. Atwood said she took the motion to say the Oklahoma position is to be taken. Commissioner Theis said that it seemed to be Texas= argument the motion favors one side, and he did not construe that is what the motion would do. He asked if it could be added to the motion that it be on the agenda that both sides make a presentation. Commissioner Smith said that circulating the rule thirty-days prior to the meeting would give notice of the proposal. Mr. Barnett stated it is unfair to assume this issue has been sprung on anyone as the Committees have reported every year on this issue. He said the Committees work for the Commission and will bring to it what the Commission decides. He said that because it will not be voted on until the next meeting, there will be ample opportunity for everyone to make comment. Commissioner Fergeson asked that the motion be re-read. Commissioner Smith said he moved that rules to compute and enforce compact compliance for Reach I, Subbasin I be written for the North Fork Red River and for Sweetwater Creek on an individual basis like the other five named interstate streams in the Subbasin. That those rules be circulated thirty days prior to the next meeting for consideration by the Commission. Commissioner Theis said that [the motion] states only one direction, that it has to be on an interstream basis. Commissioner Fergeson asked if he wanted an amendment to the motion. Commissioner Theis answered that there be a recommendation from the Engineering and Legal Committees to come up with two ways and the Commission wilt decide which way it wants to go. Otherwise, the motion says to draft it as the other five streams and it wilt be voted up or down, and if there is an alternative, then the vote would be one way or the other. Commissioner Fergeson asked Commissioner Smith if he would be willing to accept an amendment to the motion to instruct the Engineering and Legal Committees to offer at least two alternatives. Commissioner Smith said that he would accept the amendment. Commissioner Young agreed to amend his second to the motion. Commissioner Smith stated the amended motion that rules to compute and enforce compact compliance for Reach 1, Subbasin I be written for the North Fork of the Red River and Sweetwater Creek with alternative positions for the State of Oklahoma and the State of Texas. Commissioner Young seconded. Mr. Gary Ethridge interjected that if the assignment is made to make two different proposals, it is his understanding that if the water rights of any state will be effected, there is to be a unanimous vote. And how could there be a unanimous vote if one proposal favors one side and the other favors another side; we are in a loop, unless a way can be figured to not favor either state. Mr. Dean Couch, General Counsel for the Oklahoma Water Resources Board, stated that the 6-2 vote problem has been around for a number of years, and that he was unaware of any water rights of Texas on Sweetwater Creek or the North Fork of the Red that would be impaired by rules to compute and enforce compact compliance taking the Oklahoma view. He has not heard how the application to construct a reservoir for 65,000 acre-feet on Sweetwater Creek would impact water rights from a rule which is one way or the other. Oklahoma has made its presentation on some aspects, but he is unaware of where either way it goes Texas water rights are impacted.

Page 29 Mr. Ethridge stated there is difficulty in the Legal Committee even agreeing on how to get the proposal to the Commission to look at it. Texas feels Oklahoma=s position is going to adversely affect it, and he questioned what was to be accomplished. He said the issue of whether it is a 6-vote or an 8-vote needed to be decided first Mr. Robert Robbins, vice chairman of the Lugert-Altus Irrigation District, stated he had been on the District Board since 1984, that Ms. Kirby has attended the meetings.and the attorneys have worked on it. He said that all along Texas has not admitted there is problem, that there is no pending application. He said there hasn=t been a pending application because of the ARule 2000." He said he could be changed to a dry land farmer overnight and that would be disastrous. He said the farmers need to know where they are, to know whether there will be water or there won=t and he pleaded with the Commission to make a decision. Commissioner Fergeson said there has been a motion and a second, an amendment to the motion and second. He asked for the vote. He noted 6 ayes, 2 nays, with Texas casting the nay votes. Commissioner Fergeson asked if in direction to the Committees did a Asix vote= suffice. Mr. Couch responded it is his presumption that a six vote would suffice, and that he did not know what would be clearer in direction from the Commission to its Committees. Commissioner Young encouraged the Chairman to rule. Commissioner Fergeson so directed the Committees, and that Texas as host state would chair the Committee.

Mr. Barnett then asked the Commission to address the second issue, that of federal withdrawal. Commissioner Smith asked if the motion just passed would address that Mr. Barnett said it did not, and the federal withdrawal issue is more important than the 60/40. He said the District felt it is entitled to have the Compact say that it means what it says, and it will be applied to the W.C. Austin irrigation project. He said the federal government built the project with federal money prior to the Compact and were not a party to it. He asked the Commission to state it does not plan to let anyone adversely affect it. Commissioner Smith said that in response to the request, he was prepared with a second motion. He moved that rules to compute and enforce Compact compliance specify that nothing in the rules affect federal withdrawals, including the withdrawal of the Bureau of Reclamation for the W.C. Austin project, pursuant to the Compact provision, Section 2.07. He clarified that as rules are drafted, the motion is to protect federal projects that are downstream, and in this particular case, W.C. Austin. Commissioner Don Mitchell, Arkansas, seconded. Ms. Atwood argued that the issue had already been settled by a Supreme Court precedence in the 1930s. The compact overrides any previous rights associated with the compact and the federal government ratified the compact. Commissioner Fergeson asked 'rf the motion was a direction to the Committee or asking for a vote by the Commission that the federal exemptions of the Compact include the W.C. Austin project. Commissioner Young asked that the motion be re-read; Commissioner Smith re-stated the motion. The motion is that any rules in place would protect the W.CAustin project that was in place before the Compact was entered into. Commissioner Theis questioned why the project needed to be named. He said he preferred that projects not be named as a separate entity, and that the rules only refer to federal rights so that in the future rules do not have to be amended to include specific entities. Commissioner Fergeson called for a vote on the motion. The motion failed on a vote of 5-3.

Page 30 IX. FEDERAL/STATE ACTIVITY REPORTS

Representatives of the federal agencies presented reports to the Commissioners. Copies of the written reports are available as attached to the Minutes (Attachment #11). The Commissioners heard reports by Shirley Shadix, US Bureau of Reclamation; Col. Robert Crear, U.S. Army Corps of Engineers, Mississippi Valley Division—Vicksburg District- presented a computerized update on activities in the Red River Basin; Carl Hutcherson, Natural Resources Conservation Commission; Bob Blasz, Oklahoma District - U.S. Geological Survey, and Shane Barks, Arkansas District - U.S. Geological Survey. Following the presentation by the Oklahoma U.S. Geological Survey about the elimination of streamflow gages due to the Corps of Engineers1 budget reductions. Commissioner Theis said that if the COE eliminates gages that measure low flow, that is in direct opposition to the Compact which is directly related to low flows and the gaging program will be detrimental to the Compact needs. There was discussion that the Compact should draft a resolution urging the Corps of Engineers, the federal government (Congress) and NRCS, USGS and other agencies involved in the gaging program to maintain those gages with basic data that deals with the Compact. Commissioner Theis said that he would draft the resolution and circulate to signature states. The Commissioners agreed that a resolution should be prepared and circulated as a draft for comments. Commissioner Young suggested the resolution be sent to the Congressional Delegation of each member state and the President

NAVIGATION

(Within the Compact Area)

The Red River Commission and the Arkansas Soil & Water Conservation Commission (ASWCC) have agreed to sponsor the Southwest Arkansas project which will investigate the feasibility of extending navigation from Shreveport, Louisiana to Index, Arkansas.

The Corps of Engineers reauthorized the White River Navigation Project and are in the process of conducting a Feasibility Study to look into developing a nine-foot channel on the White River.

The Commission has been requested by the Arkansas Waterways Commission to complete the allocation plan for the White River. A Subcommittee of the ASWCC will work with the ASWCC staff to develop final allocation recommendations.

1999 LEGISLATIVE SESSION

The Arkansas General Assembly met in its 82nd Biennial Regular Session from January 11, 1999, until April 30,1999. Significant legislation concerning water was considered and passed.

Specific legislation impacting the Compact area includes:

• Act 1532 would create the Ouachita River Commission and Ouachita River Trust Fund similar to the existing Red River Commission of Arkansas. The Commission's purpose is to accomplish an increase in river use without any bend cuts or bend widenings. • Act 1090 entitled 'The Sparta Aquifer Critical Ground Water Counties Remediation Act" allows the creation of countywide boards to provide water to substitute for Sparta aquifer water The Act provides that the boards may assess a fee up to 36-cents per 1,000 gallons for Sparta aquifer water withdrawn. The Act as written will allow formation of boards only with five south counties declared critical ground water areas.

Page 33 General interest legislation includes Act 52 that would allow irrigation, drainage, watershed, regional water distribution and conservation districts to participate in watershed or basin studies.

Bills considered, but not passed, would have given the ASWCC additional authority for aquifers traditionally used as supplies and assessed a 4-cent per 1,000 gallon fee on most Sparta water users statewide. Funding was made for the Red River Trust Fund, the White River Trust Fund and the Ouachita River Trust Fund. Administrative funds were provided for the White River and Bayou Meto Irrigation Districts.

Resolutions in support of additional federal funding for Natural Resources Conservation Service and expressing appreciation to members of the Arkansas Congressional Delegation for their efforts in support of resolving Arkansas' ground water problems were passed.

ENVIRONMENTAL

Bayou Meto Restoration * The state of Arkansas has received a $1 million settlement over Bayou Meto Super Fund site's litigation. The state plans to cost share with federal dolEars to restore riparian buffer zones along Bayou Meto. The total potential restoration funds will equal $5 million. The Arkansas General Assembly established a committee made up of representatives of state agencies and other interest groups to manage these funds.

Mitigation Banking Program • The Memorandum of Agreement has been executed between the ASWCC and federal and state agencies which outlines the procedures by which the state sponsored mitigation banking program will operate. ASWCC staff is currently soliciting for lands to serve as potential mitigation banking sites. The state mitigation banking program will make credits available to satisfy mitigation requirements for 404 permits. Potential users will include government, public, and private entities.

Page 34 IRRIGATION PROJECTS

(Within the Compact Area)

Walnut Bayou Feasibility Study • The 82nd Arkansas General Assembly has appropriated $100,000 to fund the Walnut Bayou Irrigation Feasibility Study. Southeast Arkansas Project • The Boeuf-Tensas Irrigation District has secured funding for the first year of this feasibility study. The project proposes to utilize Arkansas River to augment existing irrigation supply in watershed.

(Outside the Compact Area)

Grand Prairie Demonstration Project • The White River Irrigation District currently is working to secure local funding for the required non-federal portion of the construction phase of their project. Congress appropriated $8 million to begin construction on the main canal and control weirs. Dutch engineers are working closely with local engineering firms on real-time operation and transport models.

Bayou Meto Project • The Corps of Engineers and NRCS are currently working on the design phase of this project. This project proposes to divert Arkansas River water to irrigate 431,000 acres in Lonoke, Prairie, Arkansas, and Jefferson Counties.

NONPOINT SOURCE POLLUTION PROGRAM

A review of the program includes:

Management Program • Arkansas has completed an update to its Management Program that addresses the nine key elements as described in the Clean Water Action Plan.

Bayou Bartholomew • ASWCC, Cooperative Extension Service, and Lincoln and Jefferson County . Conservation Districts are cooperating with the Bayou Bartholomew Alliance to deliver technical assistance and sediment management training to agricultural producers in the bayou. The goal of the project is to restore the beneficial use of aquatic life to the upper third of the bayou by reducing the sediment and turbidity load to the streams.

Page 35 Water Qualify Technician Program

• ASWCC has continued funding the water quality technician program that has resulted in a total of 25 state-funded water quality technicians. The primary function of these technicians is to prepare nutrient management plans for poultry farmers. As of December 1,1998, just over 3,100 nutrient management plans had been completed constituting roughly half of the farms in Arkansas.

Livestock Producer Water Quality Management Training

• During 1998, the Conservation Partners conducted training programs for over 4,500 poultry producers. These programs included explanation of the water quality issues associated with poultry production, especially the phosphorus problem, what BMPs are available to the farms and how to interpret their nutrient management plan. The local poultry integrators hosted the training sessions. Also, during 1998, all producers of liquid animal waste continued to receive training as required by the liquid animal waste regulations.

Illinois River

• The trend toward reduced phosphorus loading in the Illinois River continued during 1998. ASWCC implemented two new projects in the basin, one project works with livestock producers in the Cincinnati Creek area to implement practices to reduce phosphorus runoff and protect critical areas. The other project is an Urban Education/Awareness project in the Mud Creek watershed in Fayetteville. EQIP continues to make the Illinois River a priority. In 1999, the ASWCC will implement a new watershed project in the Ballard Creek watershed of the Illinois River and in the City of Rogers.

Unified Watershed Assessment

• Arkansas completed its unified watershed assessment during the summer of 1998. Seven watersheds are identified as top priority Category I waters in Arkansas. These seven waters are the Upper White River, Lower Little River, Illinois River, Strawberry River, Bayou Bartholomew, Little Red River, and the Cadron Creek. ASWCC and Arkansas Department of Environmental Quality (formerly ADPC&E) are starting to prepare the Watershed Restoration Action Strategy for the Upper White this spring. Initial steps have been taken toward organizing a citizens watershed action group in the watershed. This group will be responsible for developing the locally led conservation effort as is encouraged by the Clean Water Action Plan.

Page 36 CRITICAL GROUNDWATER AREAS

The ASWCC has designated two critical groundwater areas in Arkansas. Last year, ASWCC declared a critical groundwater area for the Sparta and alluvial aquifers in Arkansas, Jefferson, Prairie, and portions of Lonoke, Pulaski, and White Counties. In , ASWCC has previously declared a critical groundwater area for the Sparta aquifer in Union, Columbia, Ouachita, Bradley, and Caihoun Counties.

Annual Meeting Lakev'tew Lodge Beavers Bend Resort State Park Broken Bow, Oklahoma May 4, 1999

1998 CLIMATE & STREAMFLOW The Oklahoma Climatological Survey reports that state-averaged precipitation for water year 1998 was 107 percent of normal (33.71 inches). The South Central climate division was the driest (82 percent of normal) while the North Central and West Central regions were the wettest (136 percent). The statewide excess was primarily due to the very wet winter of 1997-98 which offset severely below-normal precipitation received during the last six months of the water year (April through September) - the direct opposite of the normai distribution of rainfall, in addition, the April- September average statewide temperature was 76.7 degrees F, which places 1998 in a tie with 1954 for the hottest such period ever recorded in Oklahoma.

Beginning in April 1998, much of Oklahoma suffered from devastating drought conditions. Hardest hit was the southwest region which received only 29 percent of normal precipitation between April 1 and September 30. The south central and west central regions of the state also received less than 50 percent of their average rainfall over that period. The state's agricultural industry suffered damages well in excess of $2 billion and 66 of Oklahoma's 77 counties were declared disaster areas by the federal government.

Streamflows, as measured by the USGS for water year 1998, were above normal at the six gaging stations located on the Red River - Burkburnett, Gainesville, Denison, Arthur City and DeKalb, Texas, and Terral, Oklahoma.

WEATHER MODIFICATION The Oklahoma Weather Modification Program, directed by the OWRB since the program's inception in 1996, concluded 1998 operations on October 17. The operational cloud seeding program includes the dual purposes of rainfall enhancement and hail suppression. The field program typically runs from March through October each year from bases established in Oklahoma City and Woodward. The program, funded by three consecutive legislative appropriations, conducted more than 700 total operations during the 1998 project season.

The Oklahoma Climatological Survey continues its independent evaluation of the program's effectiveness in augmenting rainfall and suppressing hail damage throughout the state. The ongoing evaluation has concluded that program results are consistent with results from similar programs in other states. More specifically, radar response images indicate precipitation and increased cloud development downwind of project operations.

To date, the State Legislature has not allocated funds for continuation of the program in 1999. However, the Legislature is currently studying various methods to fund the effort, including a cooperative state/private insurance-funded program of approximately $3 million/year. In addition, the OWRB is working with the State of Texas to obtain necessary licenses which would allow the Oklahoma weather modification contractor to conduct activities, when required, across the state line.

Page 47 WATER RESOURCES REPORTS/STUDIES • The OWRB and U.S. Geological Survey continue a cooperative study of the High Plains Aquifer in northwest Oklahoma. A digital groundwater flow model will estimate the amount of water in storage while samples collected from water wells wiSI establish baseline water quality of the aquifer. • Current OWRB Clean Lakes Section (Water Quality Division) activities include work on the following projects: • At the direction of the Oklahoma Legislature, initiation of studies to monitor and determine the impact of concentrated animal feeding operations on Oklahoma City's water supply reservoirs and the North Canadian River. •* Completion of two years of monitoring and storm sampling at Lake Arcadia, east of Edmond. • Completion of data collection on a Lake Hefner diagnostic-feasibility study and recommendations for solving sediment and nutrient problems. • Early this year, the OWRB's Technical Section (Planning and Management Division) completed a hydrologic investigation of the Arkansas River Basin in Oklahoma. The report describes water available for appropriation in the Basin's stream systems and subsystems, provides data on major reservoirs and lakes, and provides related Basin information to assist in various appropriation and water planning activities.

WATER RESOURCES FINANCING The Oklahoma Water Resources Board administers the State Financial Assistance Program (FAP), backed by the Statewide Water Development Revolving Fund, which awards loans and grants for the construction and improvement of water and sewer facilities. Loans are offered by the Board from proceeds of revenue bonds to eligible communities for sewer and water improvements and refinancing. As of April 13,1999, the Board has approved 204 bond loans totaling almost $289 million. The emergency grant program, funded by interest earnings on the Revolving Fund, has approved 432 grants for more than $24.7 million. These grants have stimulated nearly $130 million in water/wastewater projects in Oklahoma.

The Board also provides loans through the Clean Water (CWSRF) and Drinking Water Construction Revolving Fund (DWSRF) Programs for various wastewater and /distribution projects, respectively, which are often required to bring borrowers into compliance with EPA requirements. The CWSRF Loan Program, which provides funds for the construction of new wastewater facilities or the replacement or rehabilitation of existing facilities, has approved 78 loans for more than $290 million. The DWSRF, a cooperative program recently developed by the OWRB and Oklahoma Department of Environmental Quality, was created to assist municipalities and rural water districts in constructing drinking water treatment and distribution system improvements required to comply with the federal . The program has approved 3 loans for more than $9.7 million.

tn 1996, the legislature passed a bill creating the Rural Economic Action Plan (REAP) grant program, which is operated by the Board in a manner very similar to its emergency grant program. REAP gives priority to communities with populations less than 1,500 and rural water districts with less than 300 household taps. As of April, the Board has approved 151 REAP grants totaling more than $11.6 million.

For the Oklahoma portion of the Red River Compact area, the OWRB has approved more than $107 million from the three loan programs combined, almost $10.4 in emergency grants and almost $4.6 in REAP grants.

Page 48 THE 1998 OKLAHOMA LEGISLATIVE SESSION The State Legislature devoted much of its efforts during the 1998 Legislative Session to addressing various impacts of the growing swine industry as well as the effects of poultry operations on streams and lakes in eastern Oklahoma. * A statewide moratorium on the administrative processing of water use permit applications for certain kinds of swine animal feeding operations was enacted March 9,1998. Following passage of stricter legislative regulations for swine production, the moratorium was lifted in August. * The State Legislature appropriated $1 million to establish a statewide stream and groundwater monitoring program based on beneficial uses established under Oklahoma's Water Quality Standards. Under this initiative, entitled the Beneficial Use Monitoring Program (BUMP), described in detail below, the OWRB will coordinate the water monitoring activities of all state environmental agencies. • The OWRB also received a $3.5 million appropriation to match the State Drinking Water Revolving Fund capitalization grant from EPA. A separate appropriation of $3.5 million was also appropriated to the OWRB for a non-point source loan program. The loans may be made to eligible public entities to address non-point source pollution problems.

OKLAHOMA BENEFICIAL USE MONITORING PROGRAM The Beneficial Use Monitoring Program (BUMP) was created in 1998 by the Oklahoma State Legislature to establish a state monitoring program which objectively evaluates Oklahoma waters in determining their individual beneficial use support. The primary objective of BUMP, enabled through a $1 million appropriation to the OWRB, is to determine the effectiveness of point and non-point source controls in maintaining beneficial uses established in state Water Quality Standards. More specifically, the program seeks to identify waters supporting (or not supporting) designated beneficial uses, locate threatened waters, and determine water quality trends.

BUMP consists of five monitoring components, including 32 permanent sites in the Red River Compact area (see attached map): • Fixed Station Stream Monitoring, consisting of approximately 70 sites (chosen according to hydrologic units) sampled 10 times/year for selected physical and water quality parameters; • Rotating Station Stream Monitoring, approximately 60 sites located in priority areas sampled monthly, consistent with fixed station parameters; * Fixed Station Load Monitoring, which seeks to determine flow data at as many sites as possible (including USGS, Mesonet sites) to assist in determinations of wastewater load calculations; • Fixed Station Lakes Monitoring, involving quarterly sampling (possibly including biological assessments and bathymetric mapping) of approximately 40 state reservoirs; and • Fixed Station Groundwater Monitoring, which will initially compile existing groundwater data and determine if monitoring is sufficient to determine use support, then sampling programs will be established in appropriate areas.

SARDtSLAKE The OWRB, on behalf of the state of Oklahoma, continues to investigate options and measures to establish a regional water supply which would serve citizens in the Sardis Lake area of southeast Oklahoma. At the same time, the OWRB, State Dept. of Wildlife, U.S. Army Corps of Engineers and local citizens are cooperating to institute a lake level protection plan that would both set aside up to 20,000 ac-ft of water for future local uses as well as limit lake fluctuations to preserve the lake's fishery which provides substantial economic/recreational benefits to the area. Once the lake level plan is in place, involved parties will consider proposals to market the Sardis water supply to potential out-of-basin users, including the Oklahoma City Water Utilities Trust.

100 100 200 Miles RED RIVER COMPACT COMMISSION TEXAS UPDATE May 4,1999

Senate Bill 1

Senate Bill 1 (SB1) enacted by the 75th Texas Legislature in 1997, made sweeping changes related to the development and management of water resources of the state. SB1 challenged four agencies in particular to work cooperatively to implement its provisions: the Texas Water Development Board (TWDB), Texas Parks and Wildlife Department (TPWD), the Texas Agricultural Extension Service and the Texas Natural Resource Conservation Commission (TNRCC). The TNRCC works with these agencies to facilitate statewide water planning, water rights admiiustration, provision of public drinking water, water conservation, drought contingency planning and response, water quality management, and fish and wildlife management. The TNRCC's implementation of SB1 centers around rulemaking (involving enforcement, water rights, groundwater management, and water rates), water availability modeling, and water resource data coordination.

WATER AVAILABILITY MODELING ( WAM)

Overview; Article 7 of SB 1 requires the TNRCC to obtain or develop water availability models for six river basins by December 31,1999 and for the remaining 16 basins by December 31,2001. New water availability models (WAM) are being developed for (1) water rights permitting; and (2) regional and state (TWDB) planning. Within 90 days of completing a water availability model for a river basin, the TNRCC will answer the 3 specific questions set out in SB1: (1) What is the projected amount of water available to each water right holder during various low streamflow conditions?; (2) What is the amount of water that might be available if cancellation procedures were initiated?; and (3) What is the impact of reuse on existing water rights, instream uses, and freshwater inflows to bays?

Model: With the help of several engineering contractors, the TNRCC selected Texas A&M University's Water Rights Application Program (WRAP) model for water rights accounting, and the University of Texas* PrePro, a Graphical User Interface (GUI) to connect WRAP and the various database components. The contractors' recommendations also identified modifications essential for WRAP and PrePro to satisfy the evaluative criteria developed by both WAM stakeholders and the WAM Management Team.

Basin Modeling Status: The Sulphur River Basin model draft report has been completed by the contractor for that basin, R. J. Brandes Co., with the final report due in late April. Brown and Root is modeling the Neches River Basin, with the final water availability report for the Neches to be

TNRCC Implementation of Senate BUI 1 Page 1 Status Update April 5,1999 Page 51 produced in May. The Guadalupe, San Antonio, and Nueces River Basins are being modeled by HDR Engineering, with completion of the final water availability report for these three basins due in July. The Trinity, San Jacinto, Trinity- San Jacinto, and Neches- Trinity River Basins are being modeled by Espey, Padden, Consultants, Inc. The San Jacinto River Basin model will be completed by the end of 1999, in accordance with SB1 guidelines.

Additionally, the TNRCC has contracted with both Texas A&M University and the University of Texas to perform work essential to WAM. Texas A&M, as the creator of WRAP, has been selected to make modifications to the WRAP model. The University of Texas has been selected to provide geospatial data and watershed properties necessary for modeling. Both universities are working closely with the TNRCC and the basin contractors.

To complete the models for the 22 river basins by December 31,2001, the TNRCC has asked in its 2000 and 2001 LAR requests for $6.27 million. This appropriation was amended from an original request of $3.14 million to the current request of $6.27 million. The original $3.14 million estimate was based on initial estimates before any of the initial river basin models were contracted. Subsequently, the TNRCC requested Parsons ES to perform a detailed cost estimate of the funding required to complete the modeling tasks of Article 7, SB 1. The total cost estimate by Parsons ES was $5.26 million. This cost estimate does not include money for specific groundwater modeling efforts, costs to update or maintain the models, program management activities, or capital costs by the TNRCC to purchase computer equipment to run the models.

Database Development Development of new water availability models for river basins in Texas will require extensive TNRCC database development as well. The initial task for this project involved an inventory of the various databases associated with water rights administration. Scoping, analysis and design of the new database has commenced and should conclude in August 1999.

INTERAGENCY DATA COORDINATION

The firstste p in implementing the water resource data coordination goals enunciated in Article 7 of SB 1 was the development of a Memorandum of Agreement (MO A), signed by the TWDB, TPWD, and TNRCC. The TWDB serves as the lead agency in this monumental undertaking. The MOA explains how the agencies will coordinate the collection, quality assurance, and compilation of data to ensure accuracy, currency, and ready availability to citizens and water planners throughout the state.

A Data Steering Team (DST) and Water Information Integration Committee (WIIC), were created pursuant to the MOA, comprised of representatives fromth e TWDB, TPWD, and TNRCC to oversee the following data coordination efforts: (1) develop the requirements for water resource information

TNRCC Implementation of Senate BUI 1 Page 2 Status Update April 5, J 999

Page 52 (water supply numbers, water demand, population, etc.) for distribution to regional planning groups to support the development of regional water plans beginning next summer; (2) determine methods for verifying and reconciling water use data between the TNRCC and TWDB; and (3) create a long- range plan for interagency coordination on water resource data collection and dissemination. The agencies are on schedule in developing the plans for coordination and for gathering the available information for the Regional Water Planning Groups, with most of the information now available through the TWDB's Internet website.

REGIONAL WATER PLANNING GROUPS (RWPG)

SB1 required the TWDB to designate regional water planning areas and initial coordinating bodies for each RWPG. In February 1998, the TWDB adopted state and regional water planning rules, designated 16 regional water planning areas and named the initial coordinating body members of each area's regional water planning group (RWPG). Each RWPG is responsible for developing a regional water plan for its area in preparation for and response to drought conditions. All sixteen RWPG's have hired technical consultants to assist with an inventory of their regions' water resources and water use characteristics, including water drawn fromsource s within and outside each region.

Each RWPG must submit a regional water plan to the TWDB by September 1, 2000. TWDB-approved regional water plans will be incorporated into the next comprehensive State Water Plan, which is due September 1, 2001. After September 1, 2001, the TNRCC may not, without waiver, issue a water right for municipal purposes unless the water right permit addresses a water supply need in a manner that is consistent with an approved regional water plan or the State Water Plan. TNRCC rules for the development of drought contingency plans require those plans to be coordinated with the RWPG. In short, the regional water planning groups are essential to successful implementation of SB 1.

TNRCC RULEMAKING UPDATE

To implement the water resource management provisions of SB 1, the TNRCC initiated the following four rulemaking projects.

Enforcement Provisions: These rules modify Chapter 303 and 304 of Title 30 of the Texas Administrative Code (30 TAC) and will provide for the enforcement process and appeal remedies for field citations issued by a Watermaster. Also, administrative penalties for any violation of chapter 11 became part of the enforcement penalty policies. These rules were adopted at the Commission's Agenda of December 2,1998.

TNRCC Implementation of Senate Hill 1 Page 3 Status Update April 5,1999 Page 53 Water Rights and Groundwater Management: New and amended rules in Chapters 288, 293, 294,295, and 297 implement water rights and groundwater district creation and oversight provisions of Senate Bill 1. These rules provide definition and clarification for terms, procedures, and provisions related to:

• water conservation plans; • drought contingency plans; • water right applications and fees; • multi-use water rights; • reuse; • interbasin transfers; • emergency transfers; • cancellation; • aquifer storage and retrieval; • effects of hydrologic connection between surface and groundwater; • standards for evaluation of water right amendments; and • use of bed banks to transport water.

The rules also provide procedures for the designation of priority groundwater management areas, creation of groundwater conservation districts, and actions the commission may take in assuring district compliance with the requirements of the Texas Water Code, Chapter 36. An ad hoc advisory committee comprised of affected stakeholders was created to assist TNRCC staff in the development of necessary rules. The rules were adopted by the Commission at the January 27,1999 commission agenda.

Water Rates: These rules implement requirements for business plans and financial assurance for Certificates of Convenience and Necessity (CCN) applications and public water system development, and they modify reporting requirements for wholesale rates and regulatory assessments. This rulemaking project includes legislative implementation of SB 1 as well as HB 1406andSB 623. These rules were adopted January 13,1999.

Rate Flexibility: These rules modify 30 Tex. Admin.. Code Chapter 291, and will allow water and sewer rate flexibilityb y allowing rates to be based on factors other than rate of return. These rules also were adopted January 13, 1999.

RED RIVER WATERWAY PROJECT

The project is 90% complete and moving to completion with navigation features and recreational development. The Red River Waterway Commission is negotiating a Project Cooperation Agreement with the Corps to develop recreation in pools 3,4, and 5 . Actively marketing the river and ports and seeing excellent development especially at Caddo-Bossier, Natchitoches and Alexandriaports. The Corps is pursing mitigation by buying land at Loggy Bayou and Bodcau. The Commission is in communication with the Coast Guard concerning the placement of buoys and land based markers to enhance navigation aspects for industry.

Approximately $98 million in public funds (Federal, state and local) have been invested in port development on the Red River to date. Private investment at the ports adds another $ 15 million. The tonnage on the Red River Waterway is ahead of the Corps projected figuresfo r this time of development. The latest tonnage figures for 1998 were in excess of 627,000 tons shipped from public ports. Total tonnage from public and private terminals exceeded 3 million tons for 1998.

2. GROUNDWATER DATA BANK

DOTD's water well registration data file is now on the Internet, Please check it out at: www.dotd.s1^e.Ia.us/wells/mtro.html. DOTD is continuing the updating of its computerized Groundwater Data Bank and related software. The data retrieval system has been expanded to provide hard-copy printouts as well as diskettes containing various fields and in formats easily readable by users. The Data Bank presently contains data formore than 120,000 wells. The roster of DOTD licensed drillers is also on the Internet at the above listed address.

3. DOTTMJSGS COOPERATIVE WATER RESOURCES PROGRAM

The U.S. Geological Survey (USGS) under a cooperative water resources program with DOTD operates and maintains a surface water network consisting of 16 daily discharge stations, 16 daily stage stations, 21 crest gages and 14 flood profile stations. The groundwater network includes 98 water level stations and 46 chloride stations. Water levels are measured quarterly, while chloride levels are measured semiannually. The data collected

Page 55 from these stations are included in the water resources annual report which is published by USGS and is available to the public.

Louisiana and Arkansas are experiencing water level declines in the Sparta Aquifer particularly in the major pumping centers of north central Louisiana and south central Arkansas. The fear is that pumping is outdistancing recharge of the aquifer effectively mining the aquifer. DOTD has been meeting with Arkansas, the USGS, major water users, and other interested parties to study the situation and determine a course of action. USGS in cooperation with DOTD, Arkansas Soil and Water Conservation Commission and Arkansas Geological Commission, has prepared and published 1996-1997 water level report (WRI Report #97-4282) of the Sparta Aquifer for south central Arkansas and north central Louisiana. Currently there is a bill in the Louisiana Legislature, Senate Bill 912, which authorizes creation of multi-parish groundwater conservation districts throughout the state. District would be composed of major water users who would police themselves in conserving groundwater. It is expected to be passed by the Legislature this session.

5. DOTD REORGANIZATION

The 1998 Legislative Special Session enacted legislation reorganizing DOTD. Five new appointed positions have been added. We are now in the Office of Public Works and Intermodal Transportation and Mr. Curtis Patterson has been appointed Assistant Secretary. Our group is the Public Works and Water Resources Development Division, headed by Mr. Edmond Preau. The Water Resources Design Unit is now back under our control.

6. DOTD NEW LEADERSHIP

Dr. Kam Movassaghi was named the secretary of the Department in December, 1998. He was previously the Head of the Civil Engineering Department at the University of Southwestern Louisiana in Lafayette.

7. MISSISSIPPI RIVER LEVEES (Lawsuit

The EarthJustice Legal Defense Fund, Inc., filed suit on October 2, 1996, challenging the adequacy of the 1976 Environmental Impact Statement (EIS) for the ongoing Mississippi River mainline levee enlargement andberm construction feature of the Mississippi River and Tributaries Project The lawsuit sought deferral of al new construction on the main-stem Mississippi River levees until the 1976 EIS was supplemented to address environmental

Page 56 concerns. On April 4, 1997, the Corps announced the initiation of the supplemental EIS (SEIS) preparation. A Consent Decree was signed with the plaintiffs on June 17, 1998, to facilitate continued construction of certain project features during the preparation of the SEIS.

The SEIS has been completed. On October 5, 1998, Major General Phillip R. Anderson signed the Record of Decision finding that the recommended plan (Avoid and Minimize) was necessary to provide floodprotection , was the environmentally preferable plan, was in the public interest, and was in compliance with all Federal, state, and local requirements. The Avoid and Minimize plan substantially reduced the need to use forested wetlands for borrow by utilizing a variety of innovative engineering methods. Compensatory mitigation for impacts that could not be avoided, plus environmental enhancement design of borrow pits in the batture, will result in a net gain of 6,727 acres of aquatic habitat and 4,070 acres of high-quality bottomland hardwoods. Thus there has been complete compliance with the National Environmental Policy Act.

However, on December 4,1998, plaintiffs filed a challenge to the SEIS and alleged breach of the Consent Decree. The plaintiffs asserted that the SEIS was inadequate for five reasons. The Government filed its opposition motion to plaintiffs' challenge on April I, 1999. Plaintiffs' response.is due April 30,1999. The Government's reply is then due on May 15, 1999. Oral arguments are scheduled for May 26,1999. So far, the plaintiffs have not sought any injunctive relief.

At issue, basically, is the location of borrow pits. The plaintiffs want the pits on the protected side of the levee, preferably on expensive cleared farm land, rather than the traditional location on the relatively cheap, unprotected batture. In March, the Association of Levee Boards of Louisiana representing the non-Federal sponsors responsible for rights- of-way for borrow pits, filed a motion to enter an Amicus Curiae Brief.

Page 57 Page 58 REPORT OF THE LEGAL COMMITTEE at the 19th Annual Meeting of the RED RIVER COMPACT COMMISSION May 4, 1999 Lake View Lodge at Broken Bow Reservoir Broken Bow, Oklahoma

Assignments

At its 18th Annual Meeting in Hot Springs, Arkansas, the Commission made the following assignments to the Legal Committee:

1. Draft proposed revisions to the Commission's Rules for the internal Organization of the Red River Compact Commission relating to the election of a Chairman.

2. Continue the assignment of developing an institutional history involving allocation of water In the North Fork Red River system.

Responses

In response to these assignments, the Legal Committee respectfully submits the following report with recommendations:

Assignment 1. Last year in reporting on an assignment concerning the federal commissioner situation, the Legal Committee suggested that the Commission amend its Rules for Internal Organization to address the federal chair vacancy. Regarding the federal chair, the Compact itself (Section 9.01) provides as follows:

There is hereby created an interstate administrative agency to be known as the 'Red River Compact Commission', hereinafter called the 'Commission.' The Commission shall be composed of two representatives from each Signatory State who shall be designated or appointed in accordance with the laws of each state, and one Commissioner representing the United States, who shall be appointed by the President. The Federal Commissioner shall be the Chairman of the Commission but shall not have the right to vote. The failure of the President to appoint a Federal Commissioner will not prevent the operation or effect of this Compact, and the eight representatives from the Signatory States will elect a Chairman for the Commission."

Article I! of the current Rules for Internal Organization addresses the Officers of the Commission. Regarding the Chair and Vice-Chair of the Commission, the current rules provide:

2.2 "The Commissioner representing the United States shall be the Chairman of the Commission. The Chairman or designated representative of the Chairman shall preside at meetings of the Commission. His duties shall be those usually imposed upon such officers and as may be assigned by these rules or by the Commission from time to time."

Page 59 Red River Compact Commission 1999 Legal Committee Report Page 2

2.3 "The Vice-Chairman shall be elected at the annual meeting from the Commissioners of the host state for the upcoming year as reflected by the minutes, and shall hold office for a term of one year, beginning on July 1 following the election, or until a successor is elected. The Vice-Chairman shall serve as Chairman in the event the President of the United States fails to appoint a Federal Commissioner, or the absence of the Federal Commissioner or the designated representative of the Federal Commissioner."

As can be seen, rule 2.2 contemplates that the Federal Commissioner can have a "designated representative". The Legal Committee construes this provision to mean that the Federal Commissioner (provided the President has appointed a Federal Commissioner) could send a "proxy" to the Commission meeting to be the non-voting chair to conduct the meeting. However, if the President has not made an appointment there can be no "designated representative" of the Federal Commissioner.

The internal rules provide for a Chairman by default if the President fails to appoint a Federal Commissioner, or if the Federal Commissioner or the designated representative is absent. The Vice-Chairman (one of the two Commissioners from the host state) is the default Chairman by this internal rule. Being an internal rule, it appears to the Legal Committee that it can certainly be amended if the Commission intends to put a different practice into place. The following proposed amendment provides flexibility to the Commission, leaving the practice of having the Vice-Chair from the host state serve as Chair, and adding a provision about electing another person to act as Chair.

2.2 "The Commissioner representing the United States shall be the Chairman of the Commission. The Chairman or designated representative of the Chairman shall preside at meeting of the Commission. His duties shall be those usually imposed upon such officers and as may be assigned by these rules or by the Commission from time to time. If the Federal Commissioner position is vacant, the etoht representatives from the Signatory States will elect a Chairman Pro Tempore for the Commission. In such case. the eight representatives may elect a Chairman Pro Tempore from among the eight representatives of the Signatory States pursuant to these rules or from other persons who are not members of the Commission. The Chairman Pro Tempore shall serve only until the appointment of a Federal Commissioner becomes effective or until a successor Chairman Pro Tempore is elected."

2.3 "The Vice-Chairman shall be elected at the annual meeting from the Commissioners of the host state for the upcoming year as reflected by the minutes, and shall hold office for a term of one year, beginning on July 1 following the election, or until a successor is elected. Unless a Chairman Pro Tempore has been elected by the

Page 60 Red River Compact Commission 1999 Legal Committee Report Page 3

Commission pursuant to Section 2.2 of these rules. The the Vice- Chairman shall serve as Chairman in the event the President of the United States fails to appoint a Federal Commissioner, or the absence of the Federal Commissioner or the designated representative of the Federal Commissioner."

If the Commissioners wish to amend its Rules for Internal Organization at this annual meeting, the Commission will need to waive the 30-day notice requirement set forth in rule 6.1.

Assignment 2 - The matter relating to the Reach 1, Subbasin 1 apportionment rules and the North Fork Red River and Sweetwater Creek has been subject of much discussion over the years by the Commission, as well as the Legal Committee and Engineering Committee- The latest assignment from the Commission was to continue work on developing an institutional history relating to the Reach 1, Subbasin 1 apportionment provisions.

By separate cover dated April 1,1999, Donna Kirby, Manager of the Lugert-Altus Irrigation District distributed a Historic Review document relating to Reach 1, Subbasin 1 of the Compact. The Historic Review document summarizes the minutes of the 60 meetings of the Negotiating Committee beginning in March 1956 through May 1978, as well as many pertinent drafts which were discussed by the Negotiating Committee. The Historic Review document also summarizes all the annual meetings of the Commission beginning with the organizational meeting in February 1981. Legal Committee and Engineering Committee meetings are also summarized.

From a review of this Historic Review document, there does not appear to be a crystal clear statement in those documents to guide the Commission on the two major issues that have been presented:

1. How does the 60/40 allocation for Reach 1, Subbasin 1 apply to the North Fork Red River and Sweetwater Creek?

2. Do the allocation provisions of the Compact control over water rights of the Lugert-Altus Irrigation District and others which existed prior to the effective date of the Compact?

The Legal Committee notes that it provided a briefing on these Reach 1, Subbasin 1 issues to the Commission last year. A copy of that briefing paper, marked Exhibit A, is attached hereto.

The Legal Committee has no further suggestions which would be productive to resolve this issue.

Page 61 Page 62 EXHIBIT A

RED RIVER COMPACT COMMISSION LEGAL COMMITTEE April 28, 1998

BRIEFING TO COMMISSIONERS ON REACH I, SUBBASIN 1 ISSUES

Issues relating to the Reach I, Subbasin 1 provision of the Compact have been pending before the Commission for over 10 years. The Legal Committee deemed it appropriate to provide a brief background and overview of the issues to the Commission, particularly in light of appointment of new Commissioners.

The Compact is an agreement among the four states and federal government containing several points of understanding about the waters of the Red River. One of the major points of understanding relates to apportionment of water. Where watersheds of rivers or lakes are found in two or more states, the apportionment provisions generally provide percentages of flow to the states affected. The Reach I, Subbasin 1 provision apportions water between Texas and Oklahoma.

Reach I, Subbasin 1 apportionment provisions state:

"Reach I of the Red River is divided into topographic subbasins, with the water therein allocated as follows:

"SECTION 4.01. Subbasin 1 - Interstate streams - Texas.

(a) This includes the Texas portion of Buck Creek, Sand (Lebos) Creek, Salt Fork Red River, Elm Creek, North Fork Red River, Sweetwater Creek, and Washita River, together with all their tributaries in Texas which lie west of the 100th Meridian.

(b) The annual flow wthin this subbasin is hereby apportioned sixty (60) percent to Texas and forty percent to Oklahoma."

"SECTION 4.05. Special Provisions.

(a) ...

(b) Texas shall not accept for filing, or grant a permit, for the construction- of a dam to impound water solely for irrigation, flood control, soil conservation, mining and recovery of minerals, hydroelectric power, navigation, recreation and pleasure, or for any other purposes other than for domestic, municipal, and industrial water supply, on the mainstem of the North Fork Red River or any of its tributaries within Texas above Lugert-Altus Reservoir until the date that imported water, sufficient to meet the municipal and irrigation needs of Western Oklahoma is provided, or until January 1,2000, which ever occurs first/

As can be seen, there are seven named interstate streams within Subbasin 1. After flowing into Oklahoma, Sweetwater Creek joins the North Fork upstream from

Page 63 Lugert-Altus Reservoir. Representatives of the States of Texas and Oklahoma have divergent views on the meaning and intent of the Reach I provisions. These divergent views have fostered peripheral issues. The primary issue can be succinctly stated as follows:

Does the 60/40 apportionment apply to each of the named interstate streams individually (Oklahoma view), or does it apply subbasin-wide (Texas view)?

This issue first arose in a 1983 proceeding before the Texas Department of Water Resources (now Texas Natural Resources and Conservation Commission) when the Oklahoma Water Resources Board (OWRB) along with others protested a water right application by the Red River Authority of Texas to construct a 65,000 acre-feet reservoir on Sweetwater Creek in Texas. The application was later dismissed before any final ruling on the issue. Texas currently has no plans for a reservoir on Sweetwater Creek, according to the August 1997 Texas water plan entitled "Water for Texas/

The primary issue was presented again at the Commission's annual meeting in 1987 when the Engineering Committee presented draft rules to implement the Reach I, Subbasin 1 apportionment provisions. The Commission approved most of the proposals as "interim rules" which implemented the 60/40 split individuaUy for five of the seven, named streams. The Texas Member of the Engineering Committee presented a draft rule that would calculate the 60/40 spht based on the combined annual flows of the North Fork Red River and Sweetwater Creek. The Texas view would allow a Texas entity to impound up to 100% of the flow of Sweetwater Creek then make up the flow from the North Fork, as long as the combined flow into Oklahoma from the two streams calculated together equaled at least 40%. The Oklahoma Member presented a draft rule that would calculate the 60/40 split of the annual flow of the North Fork and Sweetwater Creek individually. The Commission referred the matter to the Legal Committee to work with the Engineering Committee to propose a resolution to the divergent points of view. Also notable in the 1987 annual meeting is the fact that neither Louisiana Commissioner was present, therefore, the "interim rules* that were adopted were adopted with a six to zero vote. The North Fork/Sweetwater Creek issue has been discussed at Commission annual meetings virtually every year since the 1987 meeting.

A peripheral issue arose at the Commission's 1988 annual meeting when the validity of Commission's 1987 action in approving the "interim rules* was discussed. Under Section 9.03, the Compact provides that any action concerned with Compact administration or requiring compliance with specific terms of this Compact shall require six concurring votes, but action of the Commission which affects existing water rights requires eight concurring votes. The adoption of Commission rules to implement apportionment could be construed as Compact administration. That action could also be said to affect existing water rights. It remains unresolved as to the meaning of "existing water rights."

A second peripheral issue relates to the water rights of the Lugert-Altus Irrigation District. Oklahoma has taken the view that Sections 2.07 and 2.14 protect the 1939 water right of the District separate from the interpretation of the Reach I,

Page 64 Subbasin 1 apportionment provision. On the other hand, Texas has taken the position that the Compact apportionment provision controls pursuant to case law on the effects interstate water compacts have on water rights, and that the only special provision recognized for Lugert-Altus is found in Section 4.05(b).

Engineering Advisory Committee Report Broken Bow, Oklahoma May 4, 1999

ASSIGNMENTS TO THE COMMITTEE:

1. Status of Critical USGS Stream Gages 2. Website Development

ASSIGNMENT NO. 1

The Committee was given the assignment to continue to monitor the Corps of Engineers' proposed cutbacks in the USGS stream gaging program as ft affects the Compact. Oklahoma has taken the lead in following this issue as the impact of the Corps' action has been limited to the State of Oklahoma thus far (see attached USGS website information sheet). The Oklahoma Water Resources Board met with the Tufsa District COE on April 1,1999 and requested that the COE take another look at their proposed cutbacks to see if they could be scaled back. Based on that meeting, the Tulsa COE is revisiting their cutback plan at this time. Additionally, the OWRB is in the process of preparing a Request For Proposals (RFP) for the Oklahoma stream gaging network as an alternative to the USGS Cooperative Program.

ASSIGNMENT NO. 2

The Committee was given the assignment to explore the development of a website for the Compact, Developing a commercial website would involve contracting for an internet service provider for site development along with monthly service fee for the site itself. The State of Oklahoma could possibly assist in this development through the OWRB website. OWRB staff could possibly develop appropriate web pages and host the site through the OWRB website. The Committee recommends requesting that the State of Oklahoma (OWRB) develop some example web pages for consideration by the Engineering Committee and the Commission at its next annual meeting.

Water Resources of Oklahoma Last of Corps of Engineers Stations to be Discontinued Beginning October 1,1999, due to changing priorities, the U.S. Army Corps of Engineers will no longer fund the USGS to monitor daily flow at the following sites. The Corps will only maintain the sites during periods of high water for flood discharge measurements only. Without funding the USGS will discontinue these sites.

This means accurate measurements of other flow conditions will no longer be made and accurate discharge data will no longer be available online through the internet. This eliminates any future use of these sites for updating estimates of low flow, such as the 7Q2, and other streamflow statistics. There will be insufficient data to calculate annual flow or other yields. The impact of drought on these streams will be undocumented and the availability of flow for all uses unrecorded. The Corps is not planning to maintain a database of flow conditions.

WATER RESOURCES MANAGEMENT & DEVELOPMENT PROGRAM

Oklahoma Water Supply Study, Oklahoma

The objective of this joint Oklahoma City Water Utilities Trust (OCWUT)/Reclamation project was to make small commuiuties and rural water districts in central and south central Oklahoma aware of the availability of dependable, affordable, good quality water supply from Oklahoma City's water in the McGee Creek Project. The documentation and data gathering phases were completed ahead of schedule. However, our reports writer has so far been unable to obtain from the City some of the data for our final report. A final report will be written with the data we have before the end of this year.

Lugert-Altus Water Resource Management Option?

This project began in 1997. Oklahoma Water Resources Board is the partner in this study. The study was envisioned as a multi-year study to place gauges, weirs and other measurement devices and methods within the North Fork Red River and Salt Ford Red River watersheds below Altus Dam to quantify the amount of water available for appropriation. A determination could then be made of the amount of water the district discharges to the river systems during normal operations. This discharge has considerable impact on the amount of water available for appropriations by applicants outside the District. Current operations are based on rough estimates, inefficient to quantify distribution efficiency and losses. Accurate, quantitative measurement and accounting of water downstream of Lugert-Altus is essential for water use determination and availability beyond current operations.

WATER CONSERVATION PROJECTS AND DROUGHT CONTINGENCY PLANNING

Reclamation's Water Conservation Field Services Program (WCFSP) seeks to develop projects that accomplish one or more of the following goals:

Page 73 (1) conservation planning assistance, to include technical and managerial direction; (2) demonstration and investigation of innovative water conservation technologies; (3) implementation of effective water conservation measures; and (4) water conservation information/education.

In Texas, Reclamation Drought contingency planning is a part of the water conservation program, a workshop entitled "Planning for the Next Drought" several times a year at various locales around the country and interested entities are encouraged to attend. There is no fee for this program, was granted to for assistance in drafting the drought portion of their water management plan.

WATER REUSE

Water Reuse, under Title XVI of Reclamation Projects Authorization and Adjustment Act of 1992 (H.R. 429), is being planned by the Oklahoma-Texas Area office in the Rio Grande basin and the Canadian River basin. We are not aware of any interest to participate in the program as far as the Red River basin is concerned.

In this regard, each State will be responsible for establishing clear legal authority within its State for enforcing the restrictions imposed by the Red River Compact

4. Data Reporting Procedures. a. Streamflow Gaging Station Records: The EAC will make arrangements with the Corps of Engineers, the U.S, Geological Survey and with States as required to collect daily and/or weekly data, as needed, and forward to the State Computation and Control Centers. b. Diversion Records: Each State will be responsible to collect daily and/or weekly data, as needed, and forward to the State Computation and Control Centers. c. Archived Records: Records will be archived by Commission Chairman. 5. General Compliance Requirements of Section 5.05, Red River Compact. a. Section 5.05 (b)(1): (1) Compact prescribes: "The Signatory States shall have equal rights to the use of the runoff originating in subbasin 5 and undesignated water flowing into subbasin 5, so long as the flow of the Red River at the Arkansas-Louisiana state boundary is 3,000 cubic feet per second or more, provided no state is entitled to more than 25 percent of the water in excess of 3,000 cubic feet per second." (2) In computing the Subbasin 5 water allocation, when the flow of the Red River at the Arkansas-Louisiana State Boundary is 3,000 cfs or more and the total runoff and undesignated flow of Subbasin 5 is greater than or equal to 7,500 cfs but less than or equal to 12,000 cfs, Louisiana's allocation shall be 3,000 cfs and each of the three upstream states will equally share the runoff and undesignated flow in excess of 3,000 cfs. . (3) When the total runoff and undesignated flow of Subbasin 5 is 12,000 cfs or more, each of the signatory states shall be entitled to 25% of the total runoff and undesignated flow. (4) State compliance with Section 5.05 (b)(1) does not need to be determined except when specifically requested by a Compact State. b. Section 5.05 (b)(2): (1) The Compact states: "Whenever the flow of the Red River at the Arkansas-Louisiana state boundary is less than 3,000 cubic feet per second, but more than 1,000 cubic feet per second, the States of Arkansas, Oklahoma, and Texas shall allow to flow into the Red River for delivery to the State of Louisiana a quantity of water equal to 40 percent of the total weekly runoff originating in subbasin 5 and 40 percent of undesignated water flowing into subbasin 5; provided, however, that this requirement shall not be interpreted to require any state to release stored water."

Page 158 (2) In computing the Subbasin 5 water allocation to Louisiana when flow "of Red River at the Arkansas-Louisiana State boundary is less than 3,000 cfs but more than 1,000 cfs, the Subbasin 5 runoff for each of the three upstream States and the undesignated water flowing into Subbasin 5 from each upstream State totaled, and the three upstream States should allow to pass to Louisiana 40 percent of the total, or 1,000 cfs, whichever is greater. (3) When the Subbasin 5 runoff plus undesignated water totals at least 2,500 cfs and not more than 7,500 cfs, each of the three upstream States are allocated 60 percent of its runoff plus undesignated inflow and the other 40 percent is to be allowed to flow into the Red River for delivery to Louisiana. (4) When the Subbasin 5 runoff plus undesignated water totals at least 1,000 cfs but less than 2,500 cfs, the allocation to Louisiana is 1,000 cfs because of Compact Section 5.05 (b)(3). The total Subbasin 5 runoff plus undesignated water is compared to the Louisiana allocation of 1,000 cfs and a percentage is established. Each of the three upstream States will be entitled to divert and use a quantity computed ' using (100 percent minus the established percentage) times (the total of runoff from its Subbasin 5 areas plus undesignated water flowing into its Subbasin 5 areas). (5) This Compact compliance determination should be made whenever the flow of the Red River at the Arkansas-Louisiana State boundary fells below 3,000 cfs and is more than 1,000 cfs. c. Section 5.05 (b)(3): (1) The Compact states: "Whenever the flow of the Red River at the Arkansas-Louisiana state boundary falls below 1,000 cubic feet per second, the States of Arkansas, Oklahoma, and Texas shall allow a quantity of water equal to all the weekly runoff originating in Subbasin 5 and all undesignated water flowing into Subbasin 5 within their respective states to flow into the Red River as required to maintain a 1,000 cubic foot per second flow at the Arkansas-Louisiana state boundary." (2) In computing the Subbasin 5 allocation when the flow of the Red River at the Arkansas-Louisiana State boundary falls below 1,000 cfs, and when the Subbasin 5 runoff and undesignated water flowingint o Subbasin 5 total 1,000 cfs or less, all flow must be passed to Louisiana. (3) When the Subbasin 5 runoff and undesignated water flowing into Subbasin 5 total more than 1,000 cfs but less than 2,500 cfs, Louisiana is allocated 1,000 cfs. TOs 1,000 cfs Louisiana entitlement is compared to the total runoff plus undesignated water and a percentage is established. Each of the three upstream States will be entitled to divert and use a quantity computed using (100 percent minus the established percentage) times (its total State runoff and undesignated water inflow). (4) See rules for Compact Section 5.05 (b)(2) when the Subbasin 5 runoff and undesignated water flowing into Subbasin 5 total 2,500 cfs or more up to 7,500 cfs. (5) This Compact compliance determination should be made whenever the flow of the Red River at the Arkansas-Louisiana State boundary falls below 1,000 cfs. Page 159 d. Section 5.05 (c): (1) The Compact states: "Whenever the flow at Index, Arkansas, is less than 526 cfs., the states of Oklahoma and Texas shall each allow a quantity of water equal to 40 percent of the total weekly runoff originating in Subbasin 5 within their respective states to flow into the Red River; provided however, this provision shall be invoked only at the request of Arkansas, only after Arkansas has ceased all diversions from the Red River itself in Arkansas above Index, and only if the provisions of Sub-sections 5.05 (b)(2) and (3) have not caused a limitation of diversions in subbasin 5." (2) In computing the Subbasin 5 allocation when flow of Red River at Index Arkansas is less than 256 cfs, the States of Oklahoma and Texas are to pass 40 percent of weekly runoff from respective Subbasin 5 areas. (3) This Compact compliance determination will be made only when requested by Arkansas, only after Arkansas has ceased all diversions from the Red River, and only if the provisions of subsections 5.05 (b)(2) and (3) have not caused a limitation of diversions in Subbasin 5. 6. Procedures (Disregarding Designated Flows) to Compute State Runoff, Runoff plus Undesignated Inflows, and Flow of Red River at Arkansas-Louisiana State Boundary. a. Oklahoma.

Page 162 RED RIVER COMPACT RULES AND REGULATIONS To Compute and Enforce Compact Compliance REACH I, SUBBASIN 1 (Adopted 4/30/87)

1. General. These rules and regulations to be used to compute and enforce Compact compliance within Subbasin I of Reach 1, Red River Compact, are adopted subject to the following conditions and assumptions. a. It is fully understood that these rules and regulations should be modified as new or improved gaging stations are constructed, whenever experience or detailed studies demonstrate the need for modification, and if the Commission should modify its interpretation of Compact provisions relating to this Subbasin. 2. Management of Compact Compliance Computations. a. Management Using State Centers: (1) Texas and Oklahoma representatives will establish State Computation and Control Centers. (a) State representatives will gather data, exchange data and meet prior to the annual Commission meeting to check on computation results, (b) The EAC will determine compliance with Compact. b. Management Period for Compact Compliance Computations: (1) Computation will be on the calendar year basis. (2) Water data for a calendar year should be exchanged prior to March 15 of the following year. (3) Compact Compliance Computation for a calendar year should be completed by April 15 of the following year. 3. Enforcement of Compact Compliance Requirements. Texas will be responsible for insuring that the sum of Texas uses does not exceed the total Texas water use authorized by the Red River Compact, and Texas will be responsible for establishing clear legal authority within Texas for enforcing the restrictions imposed by the Red River Compact. 4. Data Reporting Procedures. a. Streamflow Gaging Station Records: The EAC will make arrangements with federal and State agencies, as required, to collect calendar year data as needed, and forward to the Texas and Oklahoma Computation Control Centers. b. Archived Records: Records will be archived by the Commission Chairman. 5. General Compliance Requirements of Section 4.01 Red River Compact, a. SECTION 4.01. Subbasin 1 - Interstate Streams - Texas: (1) The Compact prescribes: "(a) This includes the Texas portion of Buck Creek, Sand (Lebos) Creek, Salt Fork Red River, Elm Creek, North Fork Red River, Sweetwater Creek and Washita River, together with all their tributaries in Texas which lie west of the 100th Meridian." The annual flow within this subbasin is hereby apportioned sixty (60) percent to Texas and forty (40) percent to Oklahoma."

Page 163 SECTION 4.01 is modified in part by SECTION 4.05. Special Provisions, as follows: "(b) Texas shall not accept for filing, or grant a permit, for the construction of a dam to impound water solely for irrigation, flood control, soil conservation, mining and recovery of minerals, hydroelectric power, navigation, recreation and pleasure, or for any other purpose other than for domestic, municipal, and industrial water supply, on the mainstem of the North Fork Red River or any of its tributaries within Texas about Lugert-Altus Reservoir until the date that imported water, sufficient to meet the municipal and irrigation needs of Western Oklahoma is provided, or until January 1,2000, which ever occurs first." (2) Pertinent extracts from the Supplemental Interpretive Comments of Legal Advisory Committee, as approved by the Red River Compact Commission on the 19th day of September 1978, are as follows: Pages 9 and 10 "***** The flow of interstate tributaries is generally divided 60 percent to the upstream State and 40 percent to the downstream State. Because flows in Reach I are primarily from flood flows, an annual basis of accounting was adopted"

***** "Section 4.05(b) reflects the compromise of a long-standing dispute between Oklahoma and Texas over the water of the North Fork of the Red River and Sweetwater Creek. ****** "Under the Compromise Texas will limit development on. North Fork and Sweetwater Creek to projects justified on the basis of municipal, industrial, and domestic needs until the year 2000. However, if sufficient imported water becomes available in Western Oklahoma before 2000, Texas will be free to pursue full development of its 60% of these interstate tributaries. * * * *"

(2) Until January 1,2000 (assuming that imported water is not provided prior to that date in sufficient amounts to meet municipal and irrigation needs of Western Oklahoma) special restrictions apply to Texas water use in its North Fork Red River watershed upstream from the Lugert-Altus Reservoir. Therefore, some of the Compact compliance rules for the North Fork Red River watershed upstream from the Lugert-Altus Reservoir (para 5.f.(3) &, (4) and g.(3) & (4) below) expire on January 1, 2000, if still in effect at that time. b. Buck Creek Watershed in Texas: Buck Creek watershed covers about 300 square miles in Texas. There are no existing gaging stations on Buck Creek in Texas or in Oklahoma. Since neither the Texas nor Oklahoma use of flow from Buck Creek is significant at this time, it is not required to make an annual accounting of the flow in Buck Creek. It also appears that establishing gaging stations and channel loss values so that future annual accountings could be made is not economically justified at this time. Annual accounting procedures for this watershed should be developed to provide a 60:40 apportionment whenever requested by either Oklahoma or Texas.

Page 164 c Sand (Lebos) Creek Watershed in Texas: Sand Creek watershed covers about 65 square miles in Texas. There are no gaging stations on Sand Creek in Texas or in Oklahoma. Since neither Texas nor Oklahoma makes significant use of flow from Sand Creek, it is not necessary to make an annual accounting of the flow in Sand Creek, and it does not seem to be economically justified at this time to establish gaging stations and determine channel loss values so that future annual accountings could be made. Annual accounting procedures for this watershed should be developed to provide a 60:40 apportionment whenever requested by either Oklahoma or Texas. d. . Salt Fork Red River Watershed in Texas: Salt Fork Red River watershed in Texas covers about 1,380 square miles, of which 209 are non-contributing. The USGS streamflow gage number 07300000, Salt Fork Red River near Wellington, Texas, is about 16 miles upstream from the Oklahoma-Texas State line and measures flow from a 1,222 sq. mi. drainage area, of which 209 is probably non-contributing. The average annual discharge (1953-1966) was 52,600 AF/yr, and the average annual discharge since Greenbelt Reservoir was completed (1967-1977) has been 33,250 AF/yr. The USGS streamflow gage 07300500, Salt Fork Red River at Mangum, Oklahoma, is about 29 miles downstream from the Oklahoma-Texas State line and measures flow from a 1,566 sq. mile drainage area, of which 209 is probably non-contributing. The average annual discharge (1937-1977) has been 62,450 AF/yr. (1) The actual annual delivery at the Oklahoma State line is computed as follows: (a) The annual flow at the Wellington gage, (lb) . Minus channel losses to Wellington gage flows between gage and State line (until this specific channel loss value is available, the Compact compliance calculations will be made ignoring this channel loss adjustment), (c) Plus Texas1 flow between Wellington gage and the State line. (This flow will be computed based on intervening drainage area between Wellington and Mangum gages adjusted for both Texas and Oklahoma man-made depletions.), and (d) Minus Texas' man-made depletions downstream from the Wellington gage. (2) The scheduled annual delivery at the Oklahoma State line is 40 percent of the natural flow at State line without diversions or impoundments, and would be computed as 40 percent of the following: (a) Hie actual annual delivery (para 5.d.(l) above), (b) Plus all man-made depletions in Texas, and (c) Minus the increased channel losses in Texas which would have incurred had Texas depletions not occurred (until this specific channel loss value is available, the. Compact compliance calculations will be made ignoring this channel loss adjustment). (3) Compact compliance is achieved as long as actual delivery exceeds scheduled delivery.

Page 165 e. Elm Creek Watershed in Texas: Elm Creek watershed covers about 360 square miles in Texas which includes the North Elm Creek tributary. There is no streamflow gage on Elm Creek in Texas. The USGS gage number 07303400, Elm Fork of North Fork Red River near Carl, Oklahoma, is about 6 miles downstream from the Oklahoma-Texas State line, and was used to measure flow from a 416 square mile drainage area but discharge measurements at this site were discontinued in 1980. The average annual discharge (20 years) was 30,280 AF/yr. No Compact compliance accounts can be made until the Gage near Carl has been reestablished. (1) The actual annual delivery at State line is computed as follows: (a) Flow at the State line. (This flow will be computed based on the drainage area and on the flow measured at Carl gage, adjusted for both Texas and Oklahoma depletions;), and (b) Minus Texas' man-made depletions. (2) The scheduled annual delivery at State line is 40 percent of the natural flow at State line without diversions or impoundments and would be computed as 40 percent of the following: (a) The actual annual delivery (para 5.e.(i) above), ' (b) Plus man-made depletions in Texas, and (c) Minus the increased channel losses in Texas which would have been incurred if Texas had not depleted the flow (until this specific channel loss value is available, the Compact compliance calculations will be made ignoring this channel, loss adjustment). (3) Compact compliance is achieved as long as the actual delivery exceeds the scheduled delivery. f. Washita River Watershed in Texas: There is no streamflow gage on the Washita River in Texas. The USGS streamflow gage number 07316500, Washita River near Cheyenne, Oklahoma, is over 21 miles downstream from the Oklahoma-Texas State line, and measures flow from a 794 square mile drainage area, of which about 441 square miles are in Texas. The average annual discharge at the Cheyenne gage (44 years) has been 20,720 AF/yr. (1) The actual annual delivery at Oklahoma State line is computed as follows: (a) The annual flow at the Cheyenne gage, (b) Plus channel losses to the State line flow between the State line and the gage (until this specific channel loss value is available, the Compact compliance calculations will be made ignoring this channel loss adjustment), (c) Minus Oklahoma's flow between the State line and Cheyenne gage. (This flow will be computed based on the drainage area upstream from the Cheyenne gage, adjusted for both Texas and Oklahoma man-made depletions.), and (d) Minus Texas' man-made depletions.

Page 166 (2) The annual scheduled delivery at State line is 40 percent of the natural flow at State line without diversions or impoundments, and would be computed as 40 percent of the following: (a) The actual annual delivery at State line (para 5.h.(l) above), (b) Plus man-made depletions in Texas, and (c) Minus the increased channel losses which would have occurred if Texas had not made any diversions (until this specific channel loss value is available, the Compact compliance calculations will be made ignoring this channel loss adjustment). (3) Compact compliance is achieved as long as the actual delivery exceeds the scheduled delivery.

Page 167 Page 168 RED RIVER COMPACT RULES AND REGULATIONS To Compute and Enforce Compact Compliance REACH HI, SUBBASIN 3 (as amended 4/25/89)

1. These rules and regulations to be used to compute and enforce Compact compliance within Subbasin 3 of Reach III, Red River Compact, are adopted subject to the following conditions and assumptions. a. It is fully understood that these rules and regulations should be modified whenever experience or detailed studies demonstrate the need for modification, and if the Commission should modify its interpretation of Compact provisions relating to this Subbasin. b. Definitions: (1) "Diversion", as used in these rules and regulations, is the net loss to a water source from use by a diverter, and is computed as the diversion from the water source minus the part of the diversion which is returned to the water source. Normally, return flows must be measured to be considered; however, the Engineering Committee may consider and recommend exceptions. As used herein, "diversion" is equivalent to "net diversion" from a water source and to "depletion" or "consumptive use" of a water source. (2) "Drawdown", as used in these rules and regulations, means that period commencing on the first day water ceases spilling over the existing Caddo Lake spillway (or the raised spillway, if Caddo Lake is enlarged), and continuing so long as the Caddo Lake surface elevation continues to fall, until the day when appreciable inflow reaches Caddo Lake, causing the Caddo Lake surface elevation to rise leading to a spill from Caddo Lake.

2. Management of Compact Compliance Computations. a. Management Using State Centers: (1) State Engineering Committee representatives will establish State Computation Control Centers. (a) State representatives will gather data, exchange data and meet via conference call to check on computation results, if necessary. (b) The Engineering Committee will compute compliance with Compact b. Management Period for Compact Compliance Computations: (1) Next week's State diversions will be allocated based on last week's compliance computations. (2) It is each State's responsibility to limit its total State diversion allocation among its State diverters.

General Compliance Requirements of Section 6.03 Red River Compact. a. Section 6.03 (b)(1): (1) The Compact states: "Texas shall have the unrestricted'right to all water above Marshall, Lake O' the Pines, and Black Cypress damsites; however, Texas shall not cause runoff to be depleted to a quantity less than that which would have occurred with the full operation of Franklin County, Titus County, Ellison Creek, Johnson Creek, Lake O' the Pines, Marshall, and Black Cypress Reservoirs constructed, and those other impoundments and diversions existing on the effective date of this Compact. Any depletions of runoff in excess of the depletions described above shall be charged against Texas1 apportionment of the water in Caddo Reservoir." (2) Texas may use the bed and banks of the streams or tributaries available within this Subbasin to convey its developed water downstream from the aforesaid dam sites to specified authorized users. Such water would retain its identity and would not be subject to the Caddo Lake drawdown provisions of Section 5.b. of these rules until passing the designated point of diversion. Appropriate transportation losses will be approved by the Red River Compact Commission. (3) Until both Marshall Reservoir (with an estimated capacity of 782,300 acre-feet and yield of 325,000 acre-feet annually) and Black Cypress Reservoir (with estimated capacity of 824,400 acre-feet and yield and 220,000 acre-feed annually) have been constructed, it will be virtually impossible for Texas to deplete runoff in excess of that authorized. In the future, whenever potential Texas depletions above Marshall, Lake O* the Pines, and Black Cypress damsites become a concern to Louisiana, procedures to compute Texas depletion of runoff in excess Page 170 of that authorized by Section 6.03 (b)(1) of the Compact should be developed by the Engineering Committee and presented for Commission consideration. b. Section 6.03 (b)(2): (1) The Compact states: "Texas and Louisiana shall each have the unrestricted right to use fifty (50) percent of the conservation storage capacity in the present Caddo Lake for the impoundment of water for state use, subject to the provision that supplies for existing uses of water from Caddo Lake, on date of Compact, are not reduced" (2) Whenever water is spilling over the existing spillway at 168.5 feet above mean sea level, each state may withdraw or divert water from Caddo Lake without restriction. (3) Whenever Caddo Lake is not spilling over the existing spillway at 168.5 feet above mean sea level, the total consumptive use by each state shall not exceed 8,400 acre-feet during the drawdown period, provided that neither state shall divert more than 3,600 acre-feet during any one month or 4,800 acre-feet during any two consecutive months. c. Section 6.03 (b)(3): (1) The Compact states: "Texas and Louisiana shall each have the unrestricted right to fifty (50) percent of the. conservation storage capacity of any future enlargement of Caddo Lake, provided the two states may negotiate for the release of each state's share of the storage space on terms mutually agreed upon by the two states after the effective date of this Compact" (2) . This Compact provision requires no separate computation procedures but other rules may be changed if enlargement of Caddo Lake occurs. If enlargement of Caddo Lake is authorized in the future, the Engineering Committee should review and modify as necessary Rule 5 (b) and Rule 6.

Page 171 e. Section 6.03 (c): (1) The Compact states: "In regard to the water of interstate streams which do not contribute to the inflow to Cross Lake or Caddo Lake, Texas shall have the unrestricted right to Divert and use this water on the basis of a division of runoff above the state boundary of sixty (60) percent to Texas and forty (40) percent to Louisiana."

(2) The Engineering Committee will review known Texas diversion data for the previous year and report to the Commission any Texas non-compliance with Compact Section 6.03 (c). f. Section 6.03(d): (1) The Compact states: "Texas and Louisiana will not construct improvements on the Cross Lake watershed in either state that will affect the yield of Cross Lake; provided, however, this subsection shall be subject to the provisions of Section 2.08." (2) The Engineering Committee will renew any known improvements on the Cross Lake watershed and report to the Commission any non-compliance with Compact Section 6.03 (d). 6. Caddo Lake Content Accounting Procedure During Drawdown Periods. a. Whenever water is spilled from Caddo Lake, both state's accounts are full and no accounting is necessary. Accounting shall start the first day of no-spill following each period of spilling and shall continue until the first day of spill in the next period of spilling. The accounting procedure for computing the quantity of water in Caddo Lake during periods of drawdown belonging to the States of Louisiana and Texas shall be as follows: (1) At the beginning of the drawdown, the Caddo Lake contents belong 50 percent to each state. Otherwise, begin with water ownership on Caddo Lake as shown in the most recent previous report. (2) Each State shall be credited with one-half of the inflow to Caddo Lake since the previous report. (3) Each State's account shall be reduced by its share of Caddo Lake evaporation losses during the period since the previous report (4) Each State's account shall be reduced by its diversions from Caddo Lake since the previous report (5) A State's account shall not exceed 50 percent of the capacity of Caddo Lake. If these accounting procedures result in a greater State content than 50 percent of the total capacity of Caddo Lake, the excess computed quantity shall be "spilled" into the other State's account as needed to bring the other State's account up, but in no case shall either State's account exceed 50 percent of the total capacity of Caddo Lake.

b. Using a stage-area-capacity relationship concurred in by both States, the content of Caddo Lake at the end of each accounting period shall be determined and inflow for that period shall be computed as follows: (1) From the present content, as determined above, subtract the content determined at the end of the previous period. (2) Add to the figure resulting from Step (I) the total Texas and Louisiana diversions since the end of the previous period. (3) Add to the figure resulting from Step (2) the computed gross evaporation smcelhe end of the previous period as determined in c. (2) below. This results in total inflow. Page 172 c. Evaporation will be computed as follows: (1) The Weather Bureau's pan evaporation data shall be used to compute gross lake evaporation using a standard conversion coefficient agreed to by the engineer advisors of each State. (2) The average lake surface area for the accounting period shall be determined from the stage-area-capacity relationship concurred in by both States and multiplied by the gross lake evaporation as determined in Step (1) to determine the volume of evaporation for the period.

7. Availability of Diversion Records. Arrangements shall be made for all Texas and Louisiana diverters, during "drawdown" of Caddo Lake, to maintain daily diversion records open for inspection, and to provide weekly use data as required by Rule 2 b. (3).
