Managing & Protecting California’s Water Resources
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.

Moving Toward Sustainable Groundwater Management
  • Coachella Valley Water District's Thomas E. Levy Groundwater Replenishment Facility imports Colorado River water to replenish 40,000 acre-feet of water in the Coachella Valley aquifer annually.

Two years ago, DWR began identifying priority groundwater basins under the Sustainable Groundwater Management Act (SGMA). Since then, our Sustainable Groundwater Management Program has:
  • Invested thousands of hours in outreach and community engagement
  • Developed tools like the Groundwater Basin Boundary Assessment Tool and Best Management Practices to assist local agencies in water management and planning efforts
  • Collected and shared data and information on California’s groundwater, entering more than 1.5 million groundwater elevation measurements into an online system we manage with local water districts
The year ahead brings a pivotal new deadline: SGMA requires the formation of locally-controlled groundwater sustainability agencies in California’s high- and medium-priority groundwater basins by June 30, 2017.
