Groundwater Information Center
DWR works in cooperation with local agencies and stakeholders to increase water supply reliability through the planned, coordinated use of water resources.
DWR groundwater management support activities include:California's Groundwater - Bulletin 118
We inventory essential information on the state's groundwater resources to help guide local water planning and decisions for the protection and sustainable use of groundwater. We provide summaries of available groundwater information, an updated list of references for each basin, and a Web-based version with links to supporting material and a downloadable GIS coverage of groundwater basins and boundaries.California Water Plan
The California Water Plan provides a framework for water managers, legislators, and the public to consider options and make decisions regarding California�s water future. The Plan, which is updated every five years, presents basic data and information on California�s water resources including water supply evaluations and assessments of agricultural, urban, and environmental water uses to quantify the gap between water supplies and uses. The Plan also identifies and evaluates existing and proposed statewide demand management and water supply augmentation programs and projects to address the State�s water needs.

The Office of Water Use Efficiency and Transfers provides support for the stewardship of California's water resources by promoting and facilitating the energy efficient use of water (including water transfers) and facilitates in the CALFED solution area. This office is responsible for water use efficiency planning and coordination. Our services include technical and financial assistance, information collection and dissemination, resources evaluation, and implementation, reviewing, facilitating and implementing water transfers.

Our goal is to increase water supply reliability through planned, coordinated local management and use of groundwater and surface water resources. We assist stakeholders with the planning and development of conjunctive water management projects. Funding is provided for groundwater recharge and storage, feasibility studies, and construction activities through the grant and loan programs.Drought Assistance
Our programs implement the recommendations of the Governors Advisory Drought Planning Panel, by assisting local agencies in improving groundwater management, educating private well owners in rural counties, providing technical assistance to small water systems, and assisting water districts and local governments in development of integrated water management.

IWRIS is a data management tool for water resources data. It is a web based GIS application that allows you to access, integrate, query, and visualize multiple sets of data. Some of the databases include DWR Water Data Library, California Data Exchange Center (CDEC), USGS streamflow, Local Groundwater Assistance Grants (AB303), and data from local agencies.
DWR does not:DWR does not regulate groundwater quality
The State Water Board administers water rights, water pollution control, and water quality functions for the state as part of the California Environmental Protection Agency (Cal/EPA).

Though the regulation of groundwater has been considered on several occasions, the California Legislature has repeatedly held that groundwater management should remain a local responsibility.
