From Runoff to Recharge

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.

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.

Merced River Watershed Flood-MAR Reconnaissance Study

To better understand climate vulnerabilities and how to address them, the California Department of Water Resources (DWR) conducted a three-year Merced study in partnership with Merced Irrigation District (MID) as a proof of concept to explore the effectiveness of Flood-MAR to concurrently reduce flood risk, improve water supply, and enhance ecosystems in the Merced River watershed, a tributary to the San Joaquin River. The Merced study is an exploratory watershed-scale analysis to develop and test analytical methods and models, assess climate change vulnerability, and evaluate adaptation strategies.
