The Department of Water Resources' Land and Water Use Program is tasked with collecting land use data and developing water use estimates required for statewide water planning. We accomplish this by conducting surveys of agricultural, urban and environmental land uses, collecting weather and other data required to make crop and landscape water use estimates, and developing annual estimates of land and water uses on a regional basis. The information we develop also provides the basis for the projection of future water use, the evaluation of water use efficiency measures, the development of groundwater models, and water transfers.
