Silverwood Lake is a large reservoir in San Bernardino County, California, United States, located on the West Fork Mojave River, a tributary of the Mojave River in the San Bernardino Mountains. It was created in 1971 as part of the State Water Project by the construction of the Cedar Springs Dam as a forebay on the 444-mile (715 km) long California Aqueduct (consequently inundating the former town of Cedar Springs), and has a capacity of 73,000 acre feet (90,000,000 m3).
Silverwood Lake is located on the East Branch of the California Aqueduct. It is operated by the California Department of Water Resources and provides a major water source for agencies serving nearby San Bernardino Mountain and Mojave Desert areas. Some 2,400 acres (9.7 km2) of recreation land surround the lake.
At an elevation of 3,355 feet (1,023 m), Silverwood Lake is the highest reservoir in the State Water Project.
The Pacific Crest Trail, "the jewel in the crown of America's scenic trails" spanning 2,650 miles from Mexico to Canada through three western states, passes through the Silverwood Lake State Recreation Area, with trailheads for short or long hikes.
This has prompted local media to express concerns over the large number of anglers keeping and eating fish from this popular Inland Empire lake. The California Office of Environmental Health Hazard Assessment (OEHHA) has developed a safe eating advisory for fish caught in the lake based on levels of mercury or PCBs found in local species.
