DWR Announces Initial SWP Allocation of 15 Percent by Emily Allshouse Dec 1, 2017 Water News On Thursday, Nov. 30, the California Department of Water Resources announced an initial State Water Project allocation of 15 percent for most contractors. According to DWR, the initial allocation will likely change depending on rain and snowfall received this winter. Last year, DWR’s initial allocation of 20 percent was raised to 85 percent by the end of the water year thanks to an extremely wet winter. In announcing this year’s conservative 15 percent initial allocation, DWR Director Grant Davis highlighted the need for better weather forecasting technologies. “Planning for the year and providing more accurate early estimates for water manager so they can better plan for the year is just one of the many reasons the state needs to improve our forecasting ability,” he said in a statement. With the exception of Lake Oroville, which is at a lower water level due to the spillway reconstruction project, many of the state’s major reservoirs are currently holding much more water than their historical averages. As of Nov. 30, water levels at the state’s reservoirs were: Lake Shasta: 71% capacity (119% historical average) San Luis Reservoir: 75% capacity (124% historical average) New Melones Lake: 83% capacity (147% historical average) Don Pedro: 80% capacity (123% historical average) Folsom Lake: 63% capacity (131% historical average) Lake Oroville: 36% capacity (59% historical average) Castaic Lake: 83% capacity (109% historical average) For more information about water supply conditions in the state’s reservoirs, please visit DWR’s California Data Exchange Center.
