The reservoir had its lowest recorded storage in 1991, which hovered around 25,000 acre-feet of water. Under current conditions, Cachuma is projected to reach 20,000 acre-feet of storage by October.
Cachuma is the countyâs largest water supplier, providing 35 percent of the countyâs total supply in 2012. But locations, like Lompoc, that merely get groundwater recharge from Cachuma Lake do not have the same problem as their South County neighbors who rely on Cachuma and its tunnel to deliver the bulk of their water.
