FORTY-SECOND BIENNIAL REPORT 39 



McGloud River and Squaw Creek, Shasta and Siskiyou Counties. Both the Cali- 

 fornia-Oregon Power Company and the Pacific Gas and Electric Company are 

 interested in constructing large hydroelectric projects on the McCloud River and 

 Squaw Creek. Four or five dams and powerhouses are planned and would have 

 far-reaching effects upon these outstanding trout streams. 



Pit River, Shasta County. The Pacific Gas and Electric Company is undertaking 

 the construction of the Pit 4 and Pit 6 developments. The Pit 4 project in particu- 

 lar will adversely affect a section of the Pit River which is going to be extensively 

 developed by the U. S. Forest Service for recreational use. The utility of the 

 river for recreation and fishing will be lost unless adequate flow releases can be 

 secured. 



Feather River, North Fork, Plumas County. Tlie Pacific Gas and Electric Com 

 pany is undertaking the construction of the Butte Valley-Caribou No. 2 project 

 immediately and the Belden and Poe projects in the near future. The Department 

 of Fish and Game is currently involved in negotiations in order to secure ade- 

 quate flow releases in the diverted sections of the river. 



Feather River, South Fork, and Slate Creek, Butte, Plumas, and Yuba Counties. 

 During 1951 a study was made of the proposed Oroville-Wyandotte Irrigation 

 District multiple power and irrigation development and an agreement which pro- 

 vides for release of water for fish into the streams to be affected by the proposed 

 dams was negotiated. 



Sacramento River Canals, Tehama. Butte, Glenn, and Colusa Counties. The U. S. 

 Bureau of Reclamation has proposed canals along the east and west sides of the 

 Sacramento Valley, with the Red Bank Diversion Dam near Red Bluff. It is 

 necessary that screen and fishway facilities be provided, as well as an adequate 

 flow release to maintain the downstream spawning beds. Fishing possibilities in 

 the 120 miles of canals have been studied. 



Silver Creek, El Dorado County. The Bureau of Reclamation has proposed several 

 dams and powerhouses, as a part of its Union Valley Project, which will adversely 

 affect Silver Creek and the flows of other streams in the South Fork of American 

 River drainage. 



American River, El Dorado County. The Sacramento Municipal Utility District 

 lias recently filed application with the Federal Power Commission for a power 

 project in the upper headwaters of the Rubicon and American Rivers, an area 

 that has been used almost exclusively for recreational fishing in the past. 



Sly Park Creek. El Dorado County. The Bureau of Reclamation has started con- 

 struction of the Sly Park Dam. as well as diversion dams on other streams in 

 upper El Dorado County. The Department of Fish and Game has recommended 

 that minimum flows be maintained for fish life in all streams that will be diverted. 



American River, South Fork, El Dorado County. The Pacific Gas and Electric 

 Company is rebuilding the Chute Camp Dam and the Department of Fish and 

 Game is recommending that a permanent flow be maintained in the South Fork 

 of the American River below the dam. This portion of the river has been dried 

 up during the summer since the dam was built 30 years ago. 



American River, Sacramento County. The Folsom Project, which is being built by 

 the Corps of Engineers and the Bureau of Reclamation, has been one of the major 

 water planning activities of the Department of Fish and Game for the past year. 

 The construction of Nimbus Dam will eliminate about 70 percent of the salmon and 

 steelhead spawning area in the American River and an extensive program has 

 been undertaken to conserve these runs. The program consists of securing water 

 releases and improving downstream riffles plus a hatchery installation. 



Putah Creek, Solano County. Although no anadromous fishes will be affected by 

 the construction of Monticello Dam. a Bureau of Reclamation project, the Depart- 

 ment of Fish and Game is preparing plans for the management of the reservoir. 



Stanislaus River, Middle Fork, Tuolumne County. The South San Joaquin and 

 Oakdale Irrigation Districts are undertaking the construction of three dams and 

 powerhouses on this river. The Beardsley and Donnels Dams will store and divert 

 most of the water in the upper portion of the stream and the Tulloch Dam farther 

 downstream will have an adverse effect upon the salmon run of the Stanislaus 

 River, particularly if sufficient water is not released during the spawning season.
