The previous lowest level at Folsom was 140,600 acre feet, recorded during the 1976–77 drought. An acre foot is enough water to flood an acre of land under a foot of water, and roughly the amount required by a family of four over a year.
With the recent rains, Folsom's water level has risen 28.5 feet and the reservoir is now holding 246,497 acre feet of water.
