Draft Environmental Impact Analysis of Small-Scale Hydroelectric Development in Selected Watersheds in the Upper San Joaquin River Basin, California, FERC No. 5248-999

摘要

Twelve unconstructed hydroelectric projects on ten sites located on Sand and Browns Creeks, Whisky Creek, Willow Creek, Jose and Mill Creeks, Nelder Creek, and the Lewis Fork of the Fresno River in California, are evaluated with respect to their anticipated impacts on selected target resources. The target resources include: (1) resident trout resource, (2) riparian vegetation, (3) wildlife resources, (4) sensitive species, (5) aesthetics, (6) cultural resources, (7) land use, (8) water use, (9) recreation and (10) local economy. The 12 projects would be operated as run-of-river projects. Each would normally require the installation of a diversion structure, a penstock, a powerhouse containing turbine-generators, a switchyard, transmission lines, and access roads. The total installed energy capacity of all the projects is 32 megawatts, while the average annual energy produced is estimated at 103 gigawatt hours. (ERA citation 09:045711)
