If there are “winners” from this past storm, Folsom Lake was one of them. The state reservoir rose 17 feet during the multiple-day rain storm according to the National Weather Service.
Despite the large increase, Folsom Lake is still only at 22% capacity and is less than half of where it normally is this time of year.
Other reservoirs around the state also increased; Lake Oroville rose eight feet and Lake Shasta collected about a foot of new water. Those two reservoirs are now at 37% capacity.
