California reservoirs diminish as hot, dry summer approaches

Each year Lake Oroville helps water a quarter of the nation’s crops, sustain endangered salmon beneath its massive earthen dam and anchor the tourism economy of a Northern California county that must rebuild seemingly every year after unrelenting wildfires.

While droughts are common in California, this year’s is much hotter and drier than others, evaporating water more quickly from the reservoirs and the sparse Sierra Nevada snowpack that feeds them. The state’s more than 1,500 reservoirs are 50% lower than they should be this time of year, according to Jay Lund, co-director of the Center for Watershed Sciences at the University of California-Davis. Over Memorial Day weekend, dozens of houseboats sat on cinderblocks at Lake Oroville because there wasn’t enough water to hold them. Blackened trees lined the reservoir’s steep, parched banks. At nearby Folsom Lake, normally bustling boat docks rested on dry land, their buoys warning phantom boats to slow down. Campers occupied dusty riverbanks farther north at Shasta Lake.
