They won't start storing water for water supply until the March, April timeframe, when the flood control requirements come off.. Not always applicable to off-stream reservoirs. Are California Reservoirs Filling Up? Here's California reservoir levels after atmospheric river storms A reservoir is a large body of water that is created and stored behind man-made dams. The torrential downpours over California this year have quenched some of that thirst, but on its own, this epic precipitation cant undo decades of hot, dry weather. Most reservoirs are created by damming a river to redirect its flow into a man-made basin. Overall, much of the precipitation that has fallen during the atmospheric river storms wont be stored for summer use. Any large-scale water storage project is complex and requires a high degree of planning, engineering, coordination and significant financing. It has a capacity of 2 million acre-feet (2.5 km3), which is around its design capacity of 2.15 million acre-feet (2.66 km3). In a normal year, groundwater provides about 40 percent of the states water supply. The time of highest demand for water late spring and summer is when nature provides very little precipitation to California. In some cases, such as with Shasta Lake, the reservoir is actually larger than the pre-existing lake that it was created from. Saltwater can intrude and contaminate stores. Some of the state's reservoirs have seen greater water level rises than others.
