About Folsom Lake
Folsom Lake on the American River east of Sacramento is a Bureau of Reclamation reservoir with a 466 ft full pool and Corps flood-control rules that force it to be drawn down each winter. Boat ramps at Granite Bay and Brown's Ravine close when the level drops through specific elevations, which is the reason this page exists.
