| Relation | Central Utah Project; Western Waters Digital Library; CHAPTER IV AFFECTED environment AND environmental consequences recommended plan operation of the diamond fork power system under the recommen recommend rec recommended ommen ded plan would affect streamflows stream flows in sixth water creek diamond fork and the spanish fork river the other tributaries tributa ries in the diamond fork drai dral drainage nage would not be affected under this alternative the 198400 acre feet of water diverted annually from strawberry reservoir would be conveyed to the bonneville basin through the proposed syar tunnel and in succession through syar sixth water dyne monks hollow and diamond fork powerplants Power plants flows through the powerplants power plants would be regulated by syar sixth water and monks hollow reservoirs syar reservoir would be an off stream reser voir having little effect on adjacent drainages since all operational releases would be through the corona aqueduct to sixth water reservoir sixth water creek diversions from strawberry reservoir through the existing strawberry tunnel would no longer exist an estimated 4 to 5 cfs cs of seepage would continue to flow from the existing tunnel sixth water dam and reservoir would be constructed on sixth water creek approximately 2.8 28 28 miles above its confluence with diamond fork the reservoir would have a total storage capacity of 560 acre feet at a normal water surface elevation of 6 6366 3366 feet no operational releases would be made from sixth water reservoir to sixth water creek however the natural flow including tunnel seepage up to 50 cfs cs would be re leased through sixth water dam and maintained below the dam up to 1250 cfs cs of project releases would be conveyed by the dyne aqueduct and penstock to the dyne powerplant Power plant near the confluence of sixth water creek and diamond fork diamond fork from sixth water confluence to the spanish fork river conf confluence luence project water conveyed through dyne aqueduct and dyne power plant would be released to monks hollow reservoir since the powerplant power plant would be located at the upper reach of the reservoir there would be no fluctuating powerplant power plant discharges to existing stream courses monks hollow dam and reservoir would be located on diamond fork approxi mately 8 miles northeast of its confluence with the spanish fork river monks hollow reservoir would provide long term storage through the win ter months at a normal water surface elevation of 5550 feet the total reservoir storage capacity would be 32800 acre feet the minimum water surface elevation would be 5500 feet operational releases from monks hollow reservoir to diamond fork would be conveyed through the monks hollow powerplant Power plant expected peak daily releases under project conditions for irrigation municipal and industrial use would be 875 cfs cs minimum releases would be no less than historic natural flows the diamond fork pipeline would reduce flows below the powerplant power plant tailrace by conveying up to 450 cfs cs of the total releases to the conflu conflux ence with the spanish fork river As a result the average monthly flow 116 |
