Department of Water Resources California Water Plan program computes applied, net, and depletion water balances for California. These water balances are analyses of developed and dedicated water supplies, water uses by sector, water reuses, and operational characteristics for an area. Dedicated and developed water supplies include surface water, groundwater, reused and recycled water. Water uses by sector for these analyses include parameters for agriculture, urban, managed wetlands, and water dedicated to the environment, recognizing that water is often used multiple times and benefits multiple sectors. Water balance results show what water was applied to actual uses so that use equals supply. Data provided includes water uses and supplies for WYs 2011-2015 at Detailed Analysis Unit by County (DAUCO), Planning Area (PA), Hydrologic Region (HR), and Statewide spatial scales. Computation equations, for applied, net, and depletion water balances. Standard Operating Procedures (SOPs) for data management and analyses are included in a .pdf file.
The Department of Water Resources (DWR) is responsible for managing and protecting California’s water resources. DWR works with other agencies to benefit the State’s people and to protect, restore and enhance the natural and human environments.
