Folsom Lake

Folsom Lake is a reservoir on the American River in the Sierra Nevada foothills of California, United States. Folsom Lake with its surrounding Folsom Lake State Recreation Area is one of the most visited parks in the California park system.
The lake surface area is 11,500 acres (4,700 ha), its elevation is 466 ft (142 m), and it has 75 mi (121 km) of undulated shoreline.

The lake supports a large number of recreational activities. Aquatic activities account for 85% of all recreation visits to the area, which are designated for hiking, camping, and biking. The lake is also commonly used for fishing, boating, water skiing, and horseback riding.

Fish species include largemouth bass, smallmouth bass, spotted bass, rainbow trout, Kokanee salmon, catfish, sunfish, squawfish, and carp. The California Office of Environmental Health Hazard Assessment has developed a safe eating advisory for Folsom Lake based on levels of mercury found in fish caught here.[10] The fishing is tough due to the always rising and falling water levels of the lake.
