Folsom Lake is a reservoir on the American River in the Sierra Nevada foothills of California. Folsom lake and the surrounding Folsom Lake State Recreation Area is one of the most visited parks in the California Park system. The Folsom Lake reservoir is formed by Folsom Dam, built in 1955 to control and retain the American River.
