From Runoff to Recharge
This site is under development. Stay tuned for more information on how to practice groundwater recharge in California, and check out the resources below!
Groundwater Recharge Assessment Tool (GRAT) Viewer
The GRAT public layer viewer is a map based tool that allows any user to view the public data used in GRAT. It requires no account or user log-in. It is important to note that the more extensive full functionality of GRAT, which uses significant proprietary data from each water district, can only be accessed by users from each district or GSA for their use in making resource management decisions.

Flood-MAR Hub
Flood-MAR is an important climate change adaptation strategy that can help California better prepare for and manage extreme events like floods and drought.
Water for the Future
Sustainable Conservation works with the people who drink, manage, and irrigate with groundwater to implement on-farm recharge and build large-scale watershed modeling across the Central Valley.
Earth Genome GRAT site
Earth Genome and partner Sustainable Conservation developed GRAT to help secure the California’s central industry and saving some of its key exports grown virtually nowhere else in the U.S. — like almonds.
Earth Genome siteSan Joaquin Basin Flood-MAR Watershed Studies
To better understand climate vulnerabilities and how to address them, the California Department of Water Resources conducted the San Joaquin Basin Flood-MAR Watershed Studies. This modeling effort explores the effectiveness of managed aquifer recharge using flood flows (Flood-MAR) to concurrently reduce flood risk, improve water supply, and enhance ecosystems across five watersheds that drain to the San Joaquin River. The studies demonstrate what’s possible with recharge, and the role it can play in creating a more water secure future for California.
Recharge for…
Managed Aquifer Recharge (MAR) can be an effective tool for a variety of water users looking to reduce the impacts of groundwater overdraft on their agricultural operations, communities, or local ecosystems. The new ‘Recharge For’ pages linked below offer tailored information for growers, water districts or Groundwater Sustainability Agencies, community members, ecosystem managers, and policymakers who may be interested in supporting MAR projects in their area. Specific considerations, strategies, incentives, and more are identified for these users, outlining how they can develop and implement MAR projects to build resilience and support local groundwater needs and goals.
