A plan for the Colorado River Storage project and an initial group of participating projects has been formulated by the Bureau of Reclamation in cooperation with other Federal agencies and with the States of the Upper Colorado River Basin. The project report prepared in 1950 and a supplemental report prepared in 1953 were printed as House Document No. 364, 83d Congress, 2d Session. Reports on the participating projects in the initial group, supple­ mental to the 1950 report, were also completed in 1950 and 1951. Since its introduction in the 1950 report, the project plan has been subject to modifi­ cations as shown in the 1953 supplement, in the authorizing act, and in definite plan studies.

Colorado River Storage Project / The various dams and reservoirs of the Colorado River Storage project will regulate the flow of the river, thus permitting an expansion of irrigation and other water use in the upper basin within the limits of the Colorado River Compact. In most instances powerplants and switchyards will be installed at the dams and transmission lines will be provided to transmit the power to load centers. Facilities will be provided as appropriate for repreation and to mitigate losses of, and improve conditions for, the pro.,. pagation of fish and wildlife. Minor flood control and other benefits, largely .6nevaluated at present, are anticipated from the storage project.

The Colorado River Storage project as outlined in the 1950 report included ten storage units. Four of these were authorized for construction by the act of April 11, 1956. It is anticipated that additional units will be authorized as they become needed. The four authorized units are the Glen Canypn, Flaming Gorge, Navajo, and Curecanti. Together they will provide a,bout 34,570,000 acre-feet of reservoir capacity and about 1, 108,000 kilowatts of installed generating capacity. More than three-fourths of both capacities will be provided by the Glen Canyon unit alone.

Participating Projects

Participating projects are those which will consume water of th~ Upper Colorado River system for irrigation and other purposes and which will require assistance from power revenues of the storage project in the repay­ ment of irrigation costs. An initial group of 11 participating projects was authorized by the act of April 11, 1956. These include the Paonia, Smith Fork, Florida, and Silt projects in Colorado; the Pine River project exten­ sion in Colorado and New Mexico; the Hammond project in New Mexico; the Central Utah project (initial phase) and Emery County project in Utah; and the Seedskadee, La Barge, and Lyman projects in Wyoming. The Pine River project extension has been excluded from the scheduled program of development. The remaining projects combined would provide water for a total of about 346, 460 acres, including about 115; 440 acres of full service land and about 231, 020 acres of supplemental service land.

-12- COLORADO RIVER STORAGE PROJECT CURECANTI UNIT

LOCATION: On the Gunnison River, a tributary of the Colotado River in west-central Colorado,

AUTHORIZATION: Public Law 485, 84th Congress, 2nd Session (70 Stat. 10 9) , approved April 11 , 19 5 6, subject to certification by the Secretary of the Interior ,that the benefits will exceed the cost. Such certification on two (namely, the Blue Mesa and Morrow Point) main features was made July 14, 1959. Also, Publ,ic Law 85-529 (74 Stat. 225} approved June 27, 1960.

PLAN:

The ultimate plan for the Curecanti unit includes a series of dams, reservoirs, and powerplants that would fully develop the power head along a 40-mile canyon section of the Gunnison River below Gunnison, Colorado, and above the Black Canyon of the Gunnison National Monument.

In qddition to power generation, the Curecanti unit will regulate the flow of the Gunnison River, thus providing benefits to flood control and irrigation. The reservoirs will provide extensive rec­ reational benefits, part of which will be withi~ the adjacent Gun­ nison National Forest. The reservoirs will adversely affect fis~ and wildlife resources according to estimate$ 'Of the Bureau of Sport Fisheries and Wildlife.

Flows of the Gunnison River will be large~y C?ntrolled by the Blue Mesa Reservoir, the larger and uppermost o~ the two initial reser­ voirs . Water released from the Blue Mesa Reservoir through a powerplant at the dam will receive short-term regulation at the Morrow Poii\t Reservoir immediately downstream. Water releases through the Morrow Point Dam and powerplant will be relatively uniform in order to satisfy downstream water rights and to maintain a flow of 100 second-feet or more through the Black Canyon of the Gunnison National Monument. The power output of the Blue Mesa powerplant will fluctuate to meet variations in load requirements while the Morrow Point powerplant will be operated more for base loads, particularly during the irrigation season. Power from both plants will be transmitted to load centers over transmission lines which will interconnect powerplants of the Colorado River Storage project with existing power systems in the power market area.

LOCATION: The Transmission Division facilities will be located within the states of the Upper Colorado River Basin-­ Arizona, Colorado, Utah, New Mexico and Wyoming.

AUTHORIZATION: Public Law 485 , 84th Congress, 2nd Session (70 Stat. 109), approved April 11, 1956; and Public Law 85-529 (74 Stat. 225), approved June 27, 1960.

The purpose of the Transmission Division is to deliver Colorado River Storage Project power to major load centers or to delivery points from which other agencies may transmit the power to load centers, and to interconnect the generating plants of the Colorado ,\ River Storage Project with each other and with other Federal P,roj ects. A plan for an all-Federal transmission system to accomplish such purpose was announced by the Secretary of the Interior on May 18, 1960, as a yardstick system for rate-making purposes and to evalu­ ate proposals to wheel project power over utility lines. The attached map shows the yardstick system facilities.

BENEFIT - cosr ANALYSES:

The costs of the Transmission Division are distributed among the Glen Canyon, Flaming Gorge, and Curecanti Storage units, and the Central Utah participating project for economic analyses. The benefit-cost ratio for the Transmission Division would, there­ fore, be the same as the ratio for these power producing units combined. cosr ALLOCATION AND REPAYMENT:

All costs of the Transmission Division are allocated to power and, except for $100, 000 spent on investigations from the CRD fund are reimbursable from Storage Project power revenues.

Explanation: The authorized units of the Colorado River Storage Projept, including the Transmission Division, are considered as one proJ ect in oost allocation and repayment studies. All reim­ bursable costs will be repaid from power revenues through the Upper Colorado River Basin Fund . With average selling rates of 6 mills a kilowatt-hour for firm energy, 2 . 5 mills for nonfirm ener~y, and $15 per kilowatt-year for peaking capa,city, net power revenues will be sufficient to repay the required costs of each unit of the project within 50 years following completion.

PROJECT FEATURES:

The Transmission Division includes all power transmission facil­ ities needed for the Colorado River Storage Project and partici­ pating projects excluding the switchyards at the powerplants. The yardstick system as shown on attached map includes lines and sub­ stations to deliver project power at the following points:

REMARKS:

The five major utilities in the Upper Basin States have proposed that the Federal Government build only a portion of the transmission system and that the utilities build the remaining lines or utilize exist­ ing lines to wheel project power to the points shown on the attached map. Following are the lines which the utilities feel the Federal Government should build, and the initial portions of these lines are presently programmed as indicated under "Costs:"

One 230-kv line Glen Canyon - Four Corners Two 230-kv lines Four Corners - Curecanti-Poncha {near Salida) Wood pole lines as needed from Flaming Gorge to serve Vernal, Rangely, and Craig and to interconnect the storage project with existing Colorado-Big Thompson Project factlities.

Based on the aforementioned utilities' proposal and the wheeling· rates offered by the utilities, the Bureau of Reclamation is no...y studying the proposal and its relationship to the following factors:

l. Ability of the proposed system to serve preference customers.

2. Integration of Federal power facilities.

3. Effect on the project feasibility, payout, and irrigation assistance.

After a decision has been reached regarding the wheeling proposal, further detailed programming of transmission construction will be undertaken.

CENTRAL UTAH PARTICIPATING PROJECT VERNAL UNIT

LOCATION: Northeast Utah in Ashley Valley of the Uintah Basin, approximately centered around Vernal, Utah.

AUTHORIZED: Initial phase of the Central Utah project, including the Vernal unit, authorized as a participating project with the Colorado River Storage project by the Act of April 11, 1956 (70 Stat. 105).

PIAN:

Through storage regulation and water exchanges, the Vernal unit will provide supplemental irrigation water for 14, 700 acres of land and 1, 600 acre-feet of water annually to supplement the municipal supplies of Vernal, Naples, Maeser, and surrounding ·.-. areas. The unit will also provide benefits to fish and wildlife and recreation. Excess flows of Ashley Creek will be diverted at the Ft. Thornburgh Diversion Dam into the Stanaker Feeder Canal and conveyed to the Stanaker Reservoir. Water stored in the reservoir will be released into the Stanaker Service Canal and delivered to existing irrigation canals and ditcl)es. The water will in part replace Ashley Creek water, including releases from upstream reservoirs. Some of the replaced water will be used on lands above the Stanaker Service Canal and some will be diverted from Ashley Spring on Ashley Creek into the municipal pipeline. Land drains will be provided as needed and some sections of existing canals will be lined to prevent seepage. A pipe system will be constructed for stock-watering purposes during the nonirrigation season to save for unit storage and use water now lost through open canals • Recreational and fishing attractions will be provided at Stanaker Reservoir. Small tra~ts of land distributed through the unit area will be acquired and developed for upland game, and a pump and pipeline will be installed to deliver water from Green River to the Stewart Lake State Refuge. Repayment of reimbursable construction costs will be complete in 50 years, following a 3-year development period. Irrigation costs that are beyond the repayment ability of the irrigators will be paid from the Upper Colorado River Basin Fund apportioned to Utah .

The Uintah Water Conservancy District has been organized for the purpose of contracting with the Federal Government for construction of the Vernal Unit and for repayment through the Upper Colorado River Basin Fund of certain costs relating to construction, operation, maintenance and replacement of unit works. A Contract between the Conservancy District and the United States was executed July 14, 1958. Contracts between the Uintah Water Conservancy District and the various major canal companies for the sale and use: of irrigation water were executed in November and December, 195 8. Contracts between the Conservancy District and the various towns and water companies for the sale and use of municipal water were executed in October and December, 19 5 8. The prime contract for the construction of Stanaker Dam was awarded May 4, 1959, and the scheduled completion date is January 1961. In addition, there are other features of the project under preconstruction.

The shortaye of irrigation water during the summer months has plagued this area since it was settled. Consequently, there has been considerable interest and activity on the part of the farmers and civic leaders for the construction of this unit as well as for the entire Upper Colorado River project.

AUTHORIZED: Authorized as a participating project with the Colorado River Storage Project by the Act of April 11, 1956 (70 Stat. 105).

PIAN:

A full irrigation supply will be provided from the San Juan River for 3, 900 acres of land. Most of the supply will be obtained from direct diversions of natural streamflow but when necessary natural flows will be supplemented by storage releases from the Navajo Res­ ervoir being constructed on the San Juan River as part of the Colo­ rado River Storage Project. Water will be diverted from the river by the Hammond Diversion Dam and turned into the 29-mile long Main Canal. At a point 6. 3 miles below the head of the canal the water will be diyided for distribution at three levels . Part of the water will drop through a hydraulic turbine to a continuation of the Main Canal; part will be lifted to the East and West Highline Laterals by a pump driven by the turbine; and the remainder will be diverted by gravity flow into the Gravity Extension Lateral. Smaller gravity diversions will be made from the Main Canal by five minor unnamed laterals. A project headquarters will be constructed near the pump­ ing plant. Land drains will be provided as needed. Irrigation and upland game and waterfowl will benefit from the project.

Regulated releases from Fontenelle Reservoir will be distributed for irrigation through three major canals--the VIiest Side Canal extending from the w est abutment of Fontenelle Dam, the Big Sandy Canal extending from the dam's east abutment, and the East Side Canal branching from the Big Sandy Canal. Two hydraulically driven pumps at drops in or from the \,Vest Side Canal will lift irrigation water to project lands above the canal. Thirty­ five laterals with sublaterals will branch from the three major canals to distribute water to project lands • Land drains will be provided as needed and some sections of canals and laterals will be lined to prevent seepage. In addition, initial community pasture develop­ ment work will be accomplished and some technicc;ll assistance provided for the settlers. The Seedskadee National Wildlife Refuge, covering approximately 18,000 acres, will be located along both sides of Green River in the center of the irrigable area. Its water supply will consist of return flow from irrigation of project lands, direct flow from Green River, and storage releases from Fontenelle Reservoir. Fish screens will be installed at the canal outlets from Fontenelle Reservoir, and toxicant treatments will be provided to control the rough fish populations. Basic Federal recreational facilities will be constructed at Fontenelle Reservoir.

REMARKS

A conservancy district will be organized as the project contrac\ing organization but such a district will not be formed until 25 percent of the project lands have been settled. Due to the recent discovery of trona deposits under certain areas of the project lands, it became necessary to make a reevaluation of the project itself. This reevalu­ ation is now under way.

FLORIDA PARTICIPATING PROJECT

LOCATION: Near Durango, La Plata County, Southwest Colorado, in San Juan Basin of Upper Colorado River Basin.

AUTHORIZED: As a participating project with the Colorado River Storage project by Act of April 11, 1956 (70 Stat. 105).

PLAN:

Lemon Reservoir on Florida River will regulate the flow of the river for irrigation of 19, 450 acres of land, including 5 , 730 acres not previously irrigated and 131720 acres in need of supplemental water. Regulated releases will be made from the reservoir to the Florida River. A minor part of the released water will be diverted by numerous small ditches that now serve lands in the narrow 25-mile long river valley below the reservoir. A major part of the released water will be diverted through the existing Florida Canal and the Florida Farmers Ditch to lands on Florida Mesa . The diversion dam for the Florida Farmers Ditch will be replaced and the upper 4 .9 miles of the ditch above its intersection with the Florida Canal will be enlarged . Below the intersection the Florida Canal will be enlarged for a distance of 1 .8 miles and beyond this enlargement a new lateral system will be provided to serve about 2, 210 acres of land . Except for this new lateral system, existing laterals will distribute all project water with minor rehabilitations and extensions being made to serve about 3, 520 acres in scattered tracts on Florida l'/i esa. A fish screen will be installed near the head of the Florida Farmers Ditch. No project land drains will be required. Project irrigators are willing to correct inefficient irrigation practices under prior water rights to conserve water for project development. All project lands are privately owned except 785 acres of full irriga­ tion service land that is in Indian ownership or allotments.

Two recreational areas will be developed near the Lemon Reservoir. The reservoir will also provide flood control benefits, will improve conditions for fish, and will increase recreational use of the nearby San Juan National Forest.

FRYI NGPAN-ARKANSAS PROJECT

The Ruedi Dam and Reservoir are proposed as substitutes for the Aspen Dam and Reservoir, potential features of tpe Fryingpan­ Arkansas Project., insofar as replacement water and water for future use in western Colo:-ado are concerned . In addition to satisfying requirements stemming from operation of the Fryingpan-Arkansas Project and from policy of the State of Colorado as expressed in the Colorado Water Conservancy District Act, Ruedi Dam and Reservoir would provide additional storage capa.city and water for use in western Colorado .

Description:

The Ruedi Dam and Reservoir will be located on the Fryingpan River, a tributary of the Roaring Fork River which enters the Colorado River at Glenwood Springs, Colorado . The damsite is about 14 miles east of Basalt, Colorado and about a quarter of a mile below the confluence of Ruedi Creek with the Fryingpan River. The reservoir will be about 4-1/2 miles long with a maximum width of about three­ quarters of a mile.

The dam will be an earthfill structure with crest elevation of 7780 feet m. s .1. Crest leng~h will be 1, 050 feet and heights above streambed and foundation will be 270 feet and 290 feet respectively. A glory-hole type spillway with capacity of 9, 250 cubic feet per · second will be provided, together with a tunnei outlet through the right abµtment of the dam . The reservoir outlet will ·be by tunnel through the left abutment and will have a capacity of l, 000 cfs. With normal storage c apacity of 100, 000 acre-feet, tQe water surface will cover an area of about 1, 000 acres at elevation 7764 feet m. s . 1.

Project Works:

Construction features of the project would consist of two storage reservoirs, a feeder canal, a service canal, a pumping plant, and a system of laterals . The principal storage for the project would be provided on Muddy Creek at the Spring Creek Site which is also planned to provide storage water for the Paonia project. Should the reservoir be constructed initially to a capacity of 18, 000 acre-feet as required for the Paonia project, enlargement to a total capacity of 85, 000 acre-feet would be necessary at the time the Grand Mesa project is constructed. At that time, a 3 . 5- mile feeder canal would also be constructed from Anthracite Creek to augment natural inflow to the reservoir. Cedaredge Canal would begin at Spring Creek Reservoir and would extend a distance of 67 miles in distributing water to lands of the project. The Redlands Mesa pumping plant, to be constructed on the canal near the Leroux Creek crossing, would deliver water to lands above the canal in the Redlands Mesa area. The potential 4, 000 acre-foot Gorsuch Reservoir, located on Currant Creek 12 miles from the end of Cedaredge Canal, would regulate flows of the canal as well as Currant Creek .

JUNIPER UNIT PARTICIPATING PROJECT

The plan of development for the Juniper unit as tentatively appraised involves utilization of the Juniper Dam and Reservoir sites on the Yampa River for a single-purpose irrigation development. The appraisal, how­ ever, has been made primarily as a base for future studies of hydroelectric pow·er potentialities at the Juniper and Cross Mountain Dam sites on the Yampa River. As additional studies are made, the plan will no doubt be revised to include power production as a major project purpose.

The Juniper unit as tentatively planned would serve 101, 280 acres of full service land, including 32,920 acres in Colorado and 68,360 acres in Utah, and would incidentally aid in fish and wildlife conser­ vation, recreational development, and sediment control. The lands that would be served lie along the Yampa River in the vicinity of Maybell, Colorado, and in the Deadman Bench area between the Yampa and White Rivers. The unit lands near Maybell are situated on the north and south sides of the Yampa River west of Juniper Canyon and within the basin of the Cross Mountain Reservoir, a potential but as yet unauthorized 4nit of the Colorado River Storage project. The Deadman Bench area includes lands situated along the northern slopes of the White River Basin in Colorado, on Deadman Bench proper in Utah, and between Deadman Bench and the White and Green Rivers.

YELLOW JACKET PARTICIPATING PROJECT

The Yellow Jacket unit would provide irrigation water for 41, 140 acres of land, including 36, 900 acres of full service land and 4, 240 acres of supplemental service land. The lands are situ­ ated in three rather distinct areas in the White and Yampa River Basins. The Yellow Jacket area located north and east of Meeker, Colorado, includes the lands of the White River Basin drained by Little Beaver, Coal, and Curtis Creeks. The Josephine Basin area located south of Meeker and the White River, but also in the White River drainage, includes lands in Josephine Basin and lands situated above and beyond the existing Miller ditch that diverts from the White River. The Axial Basin area located in the Yampa River drainage includes lands in Axial Basin above the water surface elevation of the potential Juniper Reservoir.

Besides providing irrigation water, the Yellow Jacket unit would incidentally benefit fish and wildlife conservation, recreation, and sediment control. In addition, if sites on the Yampa River should be developed for hydroelectric power production, excess diversions to the Yampa drainage and return flow from the Axial Basin area could be utilized for the generation of electrical energy.
