Long-Term Groundwater Replenishment Program

MID is now accepting applications for the Long-Term Groundwater Replenishment Program (GRP).

The Long-Term GRP is a voluntary, 20-year program open to all water users in the Modesto Subbasin. In wet years where MID irrigators and the City of Modesto have received full uncapped allocations, MID will make surface water available to applicants.

Applications will be accepted on a first-come, first-serve basis for the first 50% of water available. In the years where the MID Board of Directors determines the availability of GRP water, the remaining available GRP water will be held in reserve for distribution on a parity basis for applications received in the first 30 days after the determination is made.

This program is part of a series of groundwater management actions spurred by the Sustainable Groundwater Management Act. These actions are aimed at reducing reliance on pumping, promoting groundwater storage programs, improving both the availability and quality of water to disadvantaged communities, providing flood control, and protecting our groundwater for generations.

If you have questions about the GRP application process or your eligibility, please contact MID Water Operations at (209) 526-7562.
