Annual Operating Plan - Kansas River Projects 1957 Operations 1958 Outlook

INTRODUCTION

This is the fifth Annual Operating Plan for irrigation units in the Kansas River Projects area. Its primary purpose is to describe the irrigation operations and responsibilities of the Bureau of Reclam ation. It does not include operations for flood control which are the responsibility of the Corps of Engineers.

The report is concerned primarily with the Federally constructed irrigation facilities in the Republican, Solomon, and Smoky Hill River drainage areas which were in operation during 1957 or are expected to be in operation during 1958. Chapter 1 (or the Introduction) of the reoort is a brief description of the irrigation units in the Kansas River Projects Area. Chapter 11 gives a summary of actual operations during 1957. Chapter 111 presents operational estimates for 1958. The operational data regarding Harlan County Reservoir, which was constructed and is operated by the Corps of Engineers, has been prepared with the cooper- ation of the Corps.

1957 OPERATIONS

The water supply for 1957 was more than adequate to satisfy the irrigation requirements for the year. Irrigation water was delivered to 45,200 acres under Bureau-constructed systems. Above average precipitation during the irrigation season resulted in only approximately 4,200 acres of land served by privately owned pumps and canals contracting for supplemental storage water. Inflow at all reservoirs was above average and in most cases was among the wettest years of record. Reservoirs in operation were Bonny, Swanson Lake, Enders, Harry Strunk Lake, Harlan County (operated by the Corps of Engineers), Lovewell, Kirwin, Webster and Cedar Bluff. Lovewell Reservoir was placed in operation during October 1957. Controlled spills occurred at all reservoirs except Lovewell.

1958 OUTLOOK

The carryover storage in reservoirs of the Kansas River Projects area is more than adequate to meet all expected irrigation demands in 1958, even if extremely dry conditions develop. Approximately 66,500 acres of Bureau-constructed or operated systems will receive irrigation water in 1958. Under dry conditions as many as 17,000 acres under privately constructed irrigation systems may obtain supplemental water. This 17,000 acres includes 9,600 acres under the Culbertson canal which was privately constructed, although in 1957 the Bureau of Reclamation _initiated rehabilitation work on the canal.

1957 OPERATIONS - 1958 OUTLOOK

CHAPTER I - INTRODUCTION

Purpose of Report

The purpose of this Annual Operating Plan is to advise water users, cooperating agencies, and other interests of the results of irrigation operations during 1957 and the plan of irrigation operations during 1958. The report also includes a brief description of the irrigation units, including Federally-constructed canals and reservoirs.

Location and Major Features

The Kansas River Projects refers to irrigation units of the Kansas River Basin that are a part of the Missouri River Basin Project. This includes multiple-purpose reservoirs which provide storage for irrigation, flood control, municipal water supply, recreational purposes, stream pollution abatement, and other uses. The irrigation systems for these units are served by dams and reservoirs that have been constructed (and are operated) by the Bureau of Reclamation or the Corps of Engineers. The canals and diversion dams have been constructed (or rehabilitated) by the Bureau of Reclamation. The location map of the various units is shown in the general map of the Kansas River Basin (Frontispiece).

Ten reservoirs are now in operation. Eight of these (Bonny, Swanson Lake, Enders, Harry Strunk Lake, Lovewell, Kirwin, Webster, and Cedar Bluff) are operated by the Bureau of Reclamation. Two reservoirs (Harlan County and Kanopolis) are operated by the Corps of Engineers. Kanopolis Reservoir is not being used at present to serve an irrigation unit, therefore, it is not listed with other irrigation facilities re- ferred to in this report. Storage allocations for the various reservoirs are shown in Table 1 on page 13. A schematic layout of these reservoirs and the main irrigation canals is shown in Exhibit 1, page 18. Insofar as it will be practical to do so, a plan of system operation will be followed that will permit the water supply of the various reservoirs to be shared equally during periods of shortages.

Irrigation Districts

Seven irrigation districts in the Kansas River Projects area have contracted with the Bureau of Reclamation for construction of irrigation facilities. These are the Frenchman Valley, H. & R. W., Frenchman- Cambridge, and Nebraska-Bostwick in the State of Nebraska; and the Kansas- Bostwick, Kirwin, and Webster Irrigation Districts in the State of Kansas. Also the Almena Irrigation District, in Kansas, is negotiating with the Bureau for such facilities. In addition to these districts, there are possibilities that irrigation districts below Cedar Bluff and Kanopolis Reservoirs (in Kansas) will be organized during 1958. Frenaaaan vallm

Enders Reservoir and Culbertson Canal will be used to serve the Frenshman Valley Irrigalon District. The Bureau of Reclamation initiated rehabilitation work. on the Culbertson Canal during 1957; however, additional construction work is being dela-Jed pending the outcome of litigation regarding the validity of the district's repayment contract wit: the government. If storage water, to supplement the natural flow rights of the canal., sa-alt be made available in 1958 under the repeyment co tract, it can be delivered under a temporary Warren Act contract to the approximately 9)600 aeres under the canal.

The H & RW (initials for Hitchcock and Red Willow Counties) Irrigation District will be served, after enlarging and extending the Culbertson Canal now used to serve the Frenchman Valley District. Work on this is being delayed because this is affected by the same legal question affecting the Frenahman Valley District. Present schedules of construction (assuming no extended litigation) provide for deliveries of water to part of the 11,500 acres of project lands under the Culbertson Canal Extension by July 1961.

x••Gambri

Eventually the Frenchmen-Cambridge Irrigation District will receive storage water primarily from three reservoirs. Two of these, Swanson take and Harry Strunk Reservoir, are in operation. Construction of the third, Red Willow Reservoir, is being delayed until construction funds become available for it.

Ca aals now in use for the District are Cambridge, Bartley, Meeker-Driftwood (part of which is still under construction), and the old Meeker Canal (which becomes a part of the new Meeker-Driftwood system after June 1959 when that canal is expected to be completed). Two additional canals, McCook. and Red Willow, are planned for construction When a storage water supply becomes available from Red Willow Reservoir. After full development of the project a total of about 42,400 acres will be irrigated in the District. Nebraska - Bostwick.

Harlan County Reservoir is the primary source of storage water for the Nebraska-Bostwick irrigation District.- After full development by water users of the project area about 24,200 acrea. aall be irrigated in the District. The Franklin, Naponee, Franklin Pump, Superior, and Courtland Cereals have been completed to serve the district. Storage water for the Kansas-Bostwick Irrigation District is provided primarily by Harlan County and Lovewell Reservoirs. The Courtland Canal above and below Lovewell Reservoir will be used to serve approximately 49,000 acres in the District. Most of the system above Lovewell Reservoir is complete except for small areas to be served by pumps. The system below Lovewell Reservoir is expected to be completed by May 1961.

Kirwin

The Kirwin Irrigation District is comprised of a project area of about 11,500 acres. Most of the Kirwin canal system will be completed before the 1958 irrigation season. Kirwin Reservoir is used to supply storage water to the District.

Webster

The Webster Canal, now under construction, will serve 8,500 acres in the Webster Irrigation District. Some of the area may be irrigated in 1960. However, the completion of the canal system is not expected before May 1961. Storage water for the District will be supplied from Webster Reservoir.

411, Municipal Water

The city of Russell, Kansas, contracted for storage water from Cedar Bluff Reservoir to supplement their natural flow rights in 1954 through 1957. The contracts for this have been of a temporary nature because negotiations have not been completed for a long term contract.

A long term contract for supplying municipal water to the city of Norton, Kansas, appears to be in the final stages of negotiation. Actual deliveries of storage water under this contract must wait until funds become available for construction of Norton Dam and Reservoir.

There is a possibility that additional cities, such as Beloit, Kansas, may in future years consider contracting for municipal water.

3 CHAPTER II - .1.9W- OPERATIONS Precipitation

Precipitation over most of the Kansas River Projects area was above average during 1957. This resulted in less demands on reservoir storage for irrigation. The total annual precipitation at the weather stations of the various dams ranged frau 99 percent of normal at Trenton and Lovewell Dams to 156 percent of normal at Webster Data. See Table 2 on Page 14.

Streamflow

At most reservoirs the total annual inflow was one of the highest on record. At Bonny Reservoir and Swanson Lake the 1957 inflow was exceeded only in 1935. Inflows at Kirwin, Webster, and Cedar Bluff Reservoirs were second only to those of 1951. The inflows to the other reservoirs were well above normal. The total annual reservoir inflows of calendar year 1957 are compared graphically with other years of record in Exhibits 23 through 31 (Page 40 to 48). Table 3 on Page 15 shows that the inflows varied from 104 percent of normal at Enters Reservoir to over 348 percent of normal at Cedar Bluff Reservoir. Reservoir Operations - 1957

There were no irrigation shortages and controlled spills occurred at all Kansas River Projects reservoirs except Lovewell. Operation hydrographs on which are plotted reservoir content, mean monthly inflow, and mean monthly outflow are shown in Exhibits 2 through 10 (pages 19 to 27). Table 4 on Page 16 gives the monthly figures in acre feet for these values at each reservoir during 1957.

At reservoirs where the irrigation pools were filled there were no instances where the flood control pool was even half filled. In most instances less than 25 percent of the flood control pool was ever filled. The highest was 44 percent at Cedar Bluff Reservoir. This information is given so as not to give the erroneous impression that flood protection was not provided when the irrigation pools were filled and the reservoirs spilled. Bonny Reservoir

Controlled spills occurred at Bonny Reservoir during all, or parts of, the months of May through September. During September the reservoir level was lowered about three feet below the top of the irrigation pool to reduce the amount of spill releases that may be required during winter months. Releases to the Hale Ditch, a privately constructed and operated canal system, were made to satisfy natural flow rights. There was no demand for supplemental storage water. 4m. Sweason Lake

The irrigation pool in Swanson Lake was filled for the first time in May 1957. Controlled spills occurred throughout parts of May, June, July, and August. Releases for irrigation were made for Meeker- Driftwood Caaal, Bartley Canal, and supplemental requirements (under Warren Act Contracts) to the Meeker CanaL. Enders Reservoir

There was little demand for storage water in Enders Reservoir eeseee for some under Warren Act Contracts for pumps along Frenchman Ceeek and Stinking Water Creek. During most of the summer months the natural inflow was released for senior water rights downstream. Controlled spills occurred in April, May and June. Struak Lake

The mazer supply from Harry Strunk Lake was more than adequate to meet the irrigation demands of the Courtland Canal and of a few pump irrigators obtaining storage water under Warren Act Contracts. Controlled spills occurred during most of the period May through September. Harlan County Reservoir

*or The irrigation pool in Harlan County Reservoir was filled for the first time in June 1957. Controlled spills occurred during parts of Jane, July, Auguea and. December. Irrigation releases were made for the Franklin, Naponee, Franklin Pump, Superior, and Courtland Canals. During October approximately 27,000 acre-feet of water was released from Harlan. C:Jonty Reservoir for storage in Lovewell Reservoir. This resulted in a drawdownes7 almost 12 feet of the water surface elevation at Harlan County; however, this drawaown was replaced by inflow by the end of December. The traysfer was not made before October because Lovewell Dam was not completed. Levewell Reservoir

Closure in Lovewell Dam was made May 29, 1957, but planned storage aid not start until October 2, 1957. Over half of the total annual inflow of 43,100 acre-feet occurred during June. Most of this inflow was stored temporarily, but was released as soon as possible so tbat construction of the dam could be completed. No releases were made for irrigation purposes. During October approximately 28,000 acre- feet off` water from the Republican River and Harlan County Reservoir were diverted into Loam Drell Dam through the Upper Courtland Canal. Yarwin Reservoir

The irrigation pool in Kirwin Reservoir was filled for the first time ia July 1957 and controlled spills occurred during that month. This was the first year of releases to the Kirwan Canal.

5 Webster Reeeevoie

Weroster Reservoir had the irrigation pool filled for the first time during June 19;17. Controlled spills occurred during parts of July, September, and October. No releases were made for irrigation. Cedar Bluff Reeervoir

Exceptionally high inflows into Cedar Bluff Reservoir kept the reservoir level in the flood control pool during the last half of 1957. Controlled spills also occurred during this period. These spills were more than adequate to satisfy any downstream demands by pump irrigators for irrigation water. No special releases were made for the municipal water pumps of tte City of Russell, Kansas because any requirements were met by the reservoir spills.

Canal Ooerations

During 1957 the total diversions by Bureau constructed and operated canals (including the existing Meeker Canal) amounted to 96,470 acre-feet to serve 49,203 acres. This acreage included 11,468 acres in Kansas and 37,735 acres in Nebraska.

n ad hien, 388 acre-feet of surplus storage was made available under Warren Act Contracts to 4,187 acres under pump irrigation in Nebraska. Teta:_ releases of natural flow to the Hale Ditch amounted to 2,677 acre-feet for 880 acres.

Mbe.thly diversions for each canal are shown in Table 5 on Page 17. Total annual diversions for the past few years of record and acres ireigated are shown graphically in Exhibits 11. through 21 (Pages 28 to 39,,

6 /1111, CMPTF,P - ANNUAL OPERATING PLAN FOR 1958

Watel: Supply - 1958

The water sepply outlook for 1958 is excellent for all Kansas River ProSecte. 1 o khcetages for the Prejects are expected, even under the most dry vertaer conecitions because of carryover storage in the various reservoire.

The total water supply at each reservoir which will be aveilable to meet demands on the eeservoir amounts to the carryover storage from previous yeare plus the 1958 inflow. The carryover figure is easily deteemineee however., it is practically impossible to predict future inflows in areas whey e the mrsior part of the reservoir inflow results from rain flood renoff. Fez this reason, estimates of future inflows are based on a probability anarysis of recorded runoff. The "most probable" inflow was assumed to be that point on the curve where the annual historical inflow was equaLed or exeeeded 50 percent of the time. Ten percent of all the it_ storieel aerseal flows have been less than the selected reasmdle minimum" sea 10 percent have been greater than the selected reasonaW.e maximum." The probability curves were shown in last years Annual Operating Plan and are not reproduced in this report. The "most probable"; "reasonable minimum", and "reasonable maximum" values used az each reservoir are 1town in Table 3 on page 15. These values are shown graphically on Exhibits 23 through 31 (pages 40 to 48) for ready %or eueparison with historical values. Reeervoir Operations - 1958

Storage limitations at all of the reservoirs for irrigation pueposes will be limited to storage below the top of the irrigation pool. ee each reservoir as indicated in Table 1 on page 13. State laws regulating the use of water will also affect the amount and time of storing strcamflowe.

ereg asint,or months, when it is apparent that a reservoir will epill befere the steet of the next irrigation beaver., only that portion of tae inflow will be stored continuously as will be required to fill most of the irrigation pool by the first of May. This will avoid extremes in reservoir releases. Also the reservoir level will be kept lower during winter months .they high winds can cause damage to riprap by high wave actions. Continuous releases through •the river outlet at Bonny Dan during winter months is not desirable because of possible damage to the Hale Ditch outlet pipe by freezing water.

Estimates foe the calendar year 1958 showing the probable effects on eade reservoir under "most probable", "reasonable minimum", and "reason- Kole maximum" Li flea conditions are shown in. Exhibits 2 through 10 (pages 12 to 2r). Seepeep losses, which vary from 1 cfs at Swanson Lake to 8 cfs and Enders Reservoir, will be adequate to meet minimum flow requirements at Bureau operated eeservoirs. Imw 7 13212Ex_teseevoir

uarryove: storage is Bonny Reservoir will be more than adequate to meet any .1958 ierigstion requirements of supplemental storage water by the Hee Ditch. Conteolled spills will occur during 1958 even under very low teflaw eondltians. This can occur a overflow through the gated spillway or by releases terough the river outlet,. Drawdowns by making releases to the river in advance of anticipated inflow conditions which will cause the irrigation peel to more then fill are also considered controlled spills. During feseeting 'masher conditions, it is net desirable to make releases through the eutlet works oe over the spillway.

.n the future, some reduction in fluctuation of reservoir levels may be obtained by not trying to keep the level at the top of the irrigation pool during tha earner months. Sines it is desirable to enter the winter months with a eeserveir level three to four feet below the top of the irrigatiee. pool, holding the reservoir level at about 3670 feet (2 feet below tee top of the teregation pool) during the summer months would make it necessary ro masse; a drawdown of only one or two feet (instead of 3 or 1. feet) prior to winter operation. Of course, this plan of operation would be subject to revision during flood inflow or very dry weather con- ditiens. The preferable time for fall drawdown will be the month of September.

411, Swanson Lake Irr'igstf.o.e. 2e:teases from. Swanson Lake will be used primarily to serve lands under tile Meeker, new Meeker-"Driftwood, and Bartley Canals. If neeessary„ releases ray be made to assist in serving canal systems down-stream. No sheetages are an dcipated during 1958. Surplus storage may )e sold under temporary contracts to non-project systems. Swanson Lake well spill under adl inflow conditions. Enders Reservoir

aantrolled spills will occur at Enders Reservoir during 1958. S zeleases ean be made to assist in satisfying irrigation requirements of the Meeker and the Bartley Canals, altheugh this probably will not be necessary. Surplus storage may be supplied under temporary "Warren Act" eons: .et to noe-project systems and to the Culbertson Canal system. La re

Harry Strunk Lake will spill by the start of the 1958 irrigation season. The mai irrigation releases will be to the Cambridge Canal. Storage eeleases of sus:1011)e water may be madP under temporary contracts to sepplement natereL flow rights of pemp irrigators in the Medicine Creek tershed.

8 Harlan Ceuntv

Early spills will occur at Harlan County Reservoir, even under most dry inflow conditions. Irrigation releases will be male to the Franklin, Naponee, Franklin Pump, Superior and Courtland Canal in, Nebraska. Also releases will be made to the Courtland Canal and to Lovewell Reservoir in Kansae.

The plan of irrigation development for the Bostwick Division Ln Nebraska and. Kansas calls for irrigation use of Republican River flows by divertieg them through the upper Courtland Canal. 1957 was the first year that eeleases fram Harlan County Reservoir were made for Lovewell Reservoir but in the future some releases for this purpose may be expected each year. The timing and the amount of such transfers of storage will vary according to the weather conditions and the storage in both reservoirs. During the irrigator.. season, Harlan County Reservoir will be used to satisfy part of the irrigation requirements under all of the Courtland Canal ie Nebraska ard Kansas.

If caaditions permit, transfers of the larger amounts of storage water usually will not be made except during the first and last months of the irrigation season. In most years, this will be May and September. However, unesual conditions may result in transfers a month before or a month after the irrigation season. Transfers of storage during winter months will be kept to a minimum because the canal needs to be dry during that period for maintenance work. Also diversion during extremely cold weather adds to maintenance costs of canal structures.

Minimum flow releases will be made in accordance with the state- ment of opeeational objectives for Harlan County Reservoir. Lovewell. Reservelr

Lovemell Reservcir was planned for regulation of Courtland Canal flows as, well as for storage of the natural flows of White Rock Creek. The ireigaeion demands of lands under the lower Courtland Canal will be met by water from both sources. During periods of low water supply in Harlan County Reservoir and Lovewell Reservoir as much as possible of all the flow of the Republican River at the Superior-Courtland Diversion Dam that is not needed by the Superior Canal, Courtland Canal, or by downstrese =Se:A, will he diverted into Lcvewell Reservoir through the Ceurtlana ^,e:_ al. teeing extremely dry periods, such diversion maybe cant road thrrap•7k "or,-4.rrigation season except for the months of Janilary and Feeruaey_

During pert. ds of adequate carryover storage, such as now exists, diver ions three& the Courtland Canal during the non-irrigation season will be kept to a minimum. This will reduce operating and maintenance costs of the upper Ceurtland Canal. It is desirable that the reservoir %.0 9 level at Lovewell be at an elevation of approximately 1578 feet or above to reduce the possibilities of erosion of the upstream face of the dam. If conditions permit, any drawdown of Harlan County Reser- voir required to put the Lovewell elevation at 1578 feet at the end of the irrigation season will be done in September. If surplus water is available in Harlan County Reservoir and in the pickup below the Reservoir, the irrigation pool in Lovewell Reservoir will be filled (elevation 1582.6 feet) during the first month of the irrigation season. This probably will be during May.

Some releases will be made to the lower Courtland. Canal during 1958 although part of the system is still under construction. Spills are very likely during the early part of the irrigation season. Some supplemental water may be sold under Warren Act Contracts.

Kirwin Reservoir

Kirwin Reservoir will be spilling under all but dry conditions. Releases will be made to the Kirwin Canal. The project area under the Kirwin Canal is extra large for the expected available water supply and successful operation of the project will be dependent at times. upon several years of carryover reservoir storage. For this reason, it is very doubtful if supplemental storage water will be made available to non-project lands.

Webster Reservoir

Construction work on the Woodston Diversion Dam, about 26 miles below Webster Dam, will restrict reservoir releases to practically zero second-feet until about May 1, 1958 unless emergency flood conditions develop before then. Small inflows will be stored in the flood control pool during this construction period, provided that the Corps of EngIneers determine that minor storage amounts in the flood control pool will not limit overall flood protection provided by the reservoir. During the 1958 irrigation season, most of the releases will be those necessary to keep the reservoir level from rising above the top of the irrigation pool, except for storage in the flood control pool during flood emer- gencies. Some releases may be made to supplement natural flow rights under Warren Act Contracts. No irrigation requirements for project lands are expected. before 1960.

Cedar Bluff Reservoir

Carryover storage in Cedar Bluff Reservoir is much more than adequate to satisfy all expected demands on the reservoir during 1953. Water will be available to make storage releases to supplement natural flow rights of pump irrigators downstream and of the City of Russell, Kansas for municipal water.

10 Construction of a fish hatchery below Cedar Bluff Reservoir was authorized by Congress during 1957. We do not expect construction of the hatchery to be completed in time to place demands on the reservoir during 1958. The total annual use of water by the hatchery after completion is estimated to be 4,000 acre-feet.

Calla1222721122a_11258 Estimates

A teta1 cf approximately 66,500 acres under irrigation units in the Kansas River Projects area may receive irrigation water in 1958. Of this total, 45s500 acres will be in Nebraska and 21,000 acres will be in Kansas.. ExpePLed aereages and probable canal diversion requirements under "most probable". "reasonable driest year" and "reasonable wettest yeaa" are shown graphically in Exhibits 11 through 22 (pages 28 to 39). The canal requieaments for the values used in each of the three types of years are based on probability curves from data taken from water supply studies. Heti:mated acreages to be irrigated in 1958 are also listed on. Table (page 17).

In addition to the above acreages, it may be possible to deliver surplus storage vater under temporary contracts to non-project irrigation systems.

Same of the irrigation Districts in the Kansas River Projects area will opere:e all or parts of the canal systems in their districts duaieg 195. Same canal operation and maintenance will be performed by the Bureau of Reelamation. Since the canal operations may vary according to the irrigattea district under which they will be operated, the canal aperateona for 1958 are discussed under the various district headings. Frenchman Valley Irrietion District

The CeLeertson Canal and diversion dam will be operated by the Frenehaan Valley Irrigation District. Rehabilitation of the canal has been stared is the Bureau of Reclamation, and the Bureau will maintain the diaersien dam and main canal during 1958.

H. & R. W. leeigation District

Tte Bereau of Reclamation has contracted with the H. & R. W. Irrigat ion District to enlarge and extend the Culbertson Canal, operated by the French an Valley Irrigation District, to serve a new irrigation Censtruetion on this system has been delayed and there will be no canal to operata in the H. & R. W. District in 1958.

Frsuchman-1212E2 Irrigation District

In 1978 the Frenchman-Cambridge Irrigation District will operate aed maintain the Bartley and Cambridge Canals (including the Bartley and bridge Diversion Dams) which are described as Block 15f. their system. The Bureau of Reclamation will operate and maintain the Meeker Canal (including the diversion dam) and the new Upper Meeker Canal. These will not 11 be turned over t the District until more of the canal system in the Meeker-Driftwood Unit is completed. See location map. ebraska,13astaric

Tte Nebraska-Bostwick Irrigation District will operate and maintain theta canal systems. These will include the Franklin, Naponee, Pranklin Prep, Superior Canals, and the Courtland Canal. laterals (in- eluding fa deliveries from the main canal).

The only parts of the Nebraska-Bostwick Canal system that will net be operated by the district in 1958 are the Superior-Courtland Diver- sion Dam ar.d the main Courtland Canal between the diversion dam and the Nebreaku-Kansaa state line. These features will be operated and maintained by theBuresa of Reclamation in 1958 because they are also integral parts of the Kansas-Bostwick irrigation system now under construction.

Kanaas-Bostwick Irrigation District

The Kansas-Bostwick Irrigation District will operate and maintain the laterals and farm turnouts served by the Courtland Canal between the Nebraska-K&sas state line and Lovewell Reservoir. For the next year or two., tte Bu au will make deliveries to and maintain the main Court- land Canal.

Work on the Courtland Canal below Lovewell Reservoir will be completed enough to serve about 6,460 acres in 1958. The operation and maimtenance will be performed by the Bureau of Reclamation becauee the system is still under construction.
