Geography
The river begins at the confluence of Kennedy Creek and Summit Creek in the Emigrant Wilderness. It flows initially northwest, receiving the Clark Fork from the right then turning southwest, through a deep canyon to its confluence with the North Fork Stanislaus River, forming the Stanislaus River. The river drains a watershed of 332 square miles (860 km2)[4] in Tuolumne County, much of it within the Stanislaus National Forest.
Power and water infrastructure
There are four dams on the main stem of the Middle Fork – at Donnells, Beardsley, Beardsley Forebay and Sand Bar Flat. The only significant tributary impoundment is Relief Reservoir, formed by Relief Dam on Summit Creek. Middle Fork water is managed by the Spring Gap–Stanislaus hydroelectric project, owned by Pacific Gas and Electric, and the Tri-Dam project owned by the Oakdale and South San Joaquin irrigation districts.[5][6]
Tunnels connect the four mainstem reservoirs to take advantage of the hydraulic head created by the Middle Fork's steep drop. The final tunnel, from Sand Bar Flat, enters the main Stanislaus River about 2 miles (3.2 km) below the mouth of the Middle Fork, at the head of New Melones Lake reservoir. As a result, much of the Middle Fork is dewatered during the drier months.[5]
