Summary[edit]
DescriptionSalt Springs Reservoir, California (21384748818).jpg |
Salt Springs Reservoir is a reservoir in the eastern portions of Amador County and Calaveras County of California in the Sierra Nevada about 30 miles (48 km) east-northeast of Jackson. The reservoir is in the El Dorado National Forest at an elevation of 3,900 feet (1,200 m). The 141,900 acre foot (175,000,000 m3) reservoir is formed by Salt Springs Dam on the North Fork of the Mokelumne River. The concrete-faced rock-fill dam is 332 feet (101 m) tall and was completed in 1931. It is owned by Pacific Gas and Electric and its sole purpose is hydroelectricity production, though limited recreation is available. A short pipeline from the reservoir conveys water to the 44 MW Salt Springs Powerhouse. Some of the water is returned to the river downstream, but much of it flows into the Tiger Creek Conduit, a concrete flume that moves water downstream for use in other powerhouses in PG&E's Mokelumne River Project (FERC Project 137). The dam has a history of settlement problems caused by poor consolidation of the rocks during construction. The concrete face has been cracked many times by the movement, causing leaks. The surface of the dam consists of cracks, craters and shotcrete overlays. It was decided to use a flexible geomembrane to cover the portions of the dam with the greatest leakage. The installation of the membrane was completed in 2005. en.wikipedia.org/wiki/Salt_Springs_Reservoir en.wikipedia.org/wiki/Wikipedia:Text_of_Creative_Commons_... |
