The reservoir is formed by Salt Springs Dam on the North Fork of the
Mokelumne River. The
concrete-faced rock-fill
dam is 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.
The dam is being examined as the lower pool in a 380-1,140 MW
pumped-storage project with the
