Abstract

Global Climate modelers are forecasting relatively large future climate changes, with warming of 2 to 5 degrees C. The changes, if they do come to pass, would have profound impacts on California's water resources. A shift in runoff patterns would be expected with less spring snowmelt and more winter runoff. This shift will make it difficult to fill major multi-purpose reservoirs once the flood season is past, with losses in water yield and hydroelectric power. Also the predicted rise in sea level may cause problems with water transfer in the Sacramento-San Joaquin Delta. Increased risk of levee failures in the Delta and a potential increase in ocean salinity intrusion could affect water supplies of the central and southern portions of California.
