Mission

Friends of Silver Lake (FOSL) is concerned that the Southern California Edison (SCE) Rush Creek Hydroelectric Powerplant and its activities, in particular it's proposed Modified Rush Creek Hydroelectric Project under FERC relicensing and review, will negatively impact water quality and will directly accelerate accretion below the powerplant at the Rush Creek and Silver Lake delta. FOSL believes the Modified Rush Creek Hydroelectric Project will detrimentally affect endangered or protected species habitats, salmonid spawning areas, fishing, tourism, and Silver Lake water quality as well as potentially impact downstream waterways. Possible downstream impacts could also affect the interests of several CA tribes and the Los Angeles Department of Water and Power diversion project at Grant Lake. Any Grant Lake impact could negatively affect Mono Lake.
