What this level means
Folsom Lake is operated for flood control and water supply on the American River, so it fills in spring and draws down through the dry season. The California Data Exchange Center publishes a daily reservoir elevation and storage figure for station FOL, which is what this page tracks. There is no active U.S. Geological Survey lake gauge for the reservoir.
How this reading is taken
CDEC - California Data Exchange Center (DWR) measures the water surface and publishes the value continuously. This page stores the latest reading at build time and refreshes the record daily, so the figure above is a real measurement rather than a model or an estimate.
No operating agency publishes a full pool elevation for Folsom Lake that we can cite, so this page shows the reading and its trend without a percentage.
Elevations are given in feet above the gauge datum used by the operating agency. Two lakes are only comparable with each other through how full they are, not through their raw elevation, because each dam sits at a different height.
