North Fork Stanislaus River Hydroelectric Development Project

The North Fork Stanislaus River Hydroelectric Development Project extends over a distance of nearly 40 miles in the counties of Alpine, Tuolumne and Calaveras. Its upper­most structure is located at an average elevation of 6,700 feet in Alpine County and the lower end of the Project is at a mean elevation of 1,100 feet at Clark's Flat in Calaveras County. The project features are accessible from points along State Highway 4, northeast of its intersection with State Highway 49 at Angels Camp. The Project layout is shown on the "General Plan and Project Plan" (Attached Drawing 1029-C-0010).
The Project consists of 1) a diversion dam on the North Fork Stanislaus River, imme­diately downstream of the confluence of Silver and Duck Creeks; 2) a diversion tunnel leading to New Spicer Meadow Reservoir; 3) a dam immediately downstream of and replacing Spicer Meadow Dam on Highland Creek; 4) a powerhouse on the outlet works of New Spicer Meadow Dam; 5) a diversion dam on Beaver Creek, downstream of Calaveras Big Trees State Park and a short tunnel and penstock leading to McKays Point Reservoir; 6) a diversion dam on the North Fork Stanislaus River at McKays Point; 7) a tunnel and shaft configuration from McKays Point Reservoir to the Collierville Power­house at Clark Flat; 8) the Collierville Powerhouse at Clark Flat on the Stanislaus River, approximately one mile below the confluence of the North and Middle Forks of the Stanislaus River; 9) access roads; 10) two transmission lines; and 11) appurtenant facilities.
