Silverwood Lake is a largereservoir inSan Bernardino County, California, United States, located on theWest Fork Mojave River, atributary of theMojave River in theSan Bernardino Mountains. It was created in 1971 (54 years ago) (1971) as part of theState Water Project by the construction of the Cedar Springs Dam as aforebay on the 444 mi (715 km) longCalifornia Aqueduct (consequently inundating the former town of Cedar Springs)[1] and has a capacity of 73,000 acre⋅ft (90,000,000 m3).[2]
Silverwood Lake is located on the East Branch of theCalifornia Aqueduct. It is operated by theCalifornia Department of Water Resources and provides a major water source for agencies serving nearbySan Bernardino Mountain andMojave Desert areas. Some 2,400 acres (9.7 km2) of recreation land surround the lake.[3]

The Silverwood Lake State Recreation Area is one ofmany California State Parks features picnicking, hiking trails, swimming beaches, and designated areas for boating, water-skiing and fishing.[4]
ThePacific Crest Trail, "the jewel in the crown of America's scenic trails" spanning 2,650 mi (4,260 km) from Mexico to Canada through three western states, passes through the Silverwood Lake State Recreation Area, with trailheads for short or long hikes.[5]
A 2009 California Water Board study found significantly elevated levels of toxic poly-chlorinated biphenyls (PCBS) and mercury levels in largemouth bass at Silverwood Reservoir.[6][7][8]
This has prompted local media to express concerns over the large number of anglers keeping and eating fish from this popular Inland Empire lake.[8][9][10] TheCalifornia Office of Environmental Health Hazard Assessment (OEHHA) has developed a safe eating advisory for fish caught in the lake based on levels of mercury orPCBs found in local species.[11]
