Folsom Lake rises 15 feet after weekend rains

GRANITE BAY, Calif. (KCRA) —

Runoff from the rainy weekend continues to spill into Northern California reservoirs -- in some cases doubling the water stored in area lakes.

Folsom Lake picked up more than 100,000 acre-feet of water between noon on Saturday and noon on Sunday.

The lake also increased by more than a tenth of its capacity during the same 24-hour period.

The surge in water flowing from the north and south forks of the American River caused the lake's level to rise more than 12 feet during that time.

But by Monday morning, Folsom Lake was 15 feet higher than it was Friday afternoon and 127 percent of normal capacity for this time of year.

Shasta Lake, one of the regions largest reservoirs, also saw impressive inflows over the weekend.

The reservoir was 108 percent of average and 66 percent of capacity, as of Monday morning.

Another soaking rain is forecast to hit the area Tuesday afternoon and last through Thursday. Track the wet weather with Interactive Radar.

Some areas of the Sierra foothills and mountains could see 4 to 9 inches of additional rain, according to the National Weather Service.

Flood warnings have been issued for some creeks and rivers.
