At the end of the irrigation season, any fish in the <br />canal presumably find their way into the Uncompahgre River <br />or a connecting lateral or canal, or they are trapped in the <br />South Canal when flow into the canal from the Gunnison River <br />is stopped. The proposed hydroelectric projects will oper- <br />ate 12 months per year, subject to occasional canal mainten- <br />ance shutdowns. These maintenance shutdowns are anticipated <br />to occur no more than once a year. Therefore, the fishery <br />should not be subjected to any more canal dewatering cycles <br />than at present. <br /> <br />Trashracks will be constructed at the intake of each project <br />to assist in minimizing fish passage through the turbines. <br />Some mortality or injury to fish passing through the tur- <br />bines is inevitable. However, there may not be any incre- <br />mental adverse impact due to turbine passage, since the <br />canal fishery is eliminated on yearly basis under the pre- <br />sent operation. <br /> <br />Hydroelectric plants are clean, non-consumptive and rela- <br /> <br />tively noiseless. Therefore, the operation of the proposed <br /> <br />E-311 <br />
