Chowchilla Subbasin Groundwater Recharge Project 2 (Streambed Alteration Agreement No. EPIMS-MAD-48140-R4).

The California Department of Fish and Wildlife has entered into Streambed Alteration Agreement EPIMS-MAD-48140-R4 with Madera County for the Chowchilla Subbasin Groundwater Recharge Project 2. Located at the Eastside Bypass of the San Joaquin River in Madera County, the project is designed to divert flood flows to support groundwater recharge and drought mitigation. The scope of work includes the construction of a water diversion facility featuring a fish screen, a concrete control box, a buried reinforced concrete pipeline under the levee, and a reinforced concrete pump box that delivers water into a 31-acre recharge basin. The project is authorized under Section 1602 of the California Fish and Game Code and is exempt from CEQA review pursuant to Executive Order N-7-22, which suspends certain environmental requirements for drought-related recharge projects. Administrative oversight is managed by the California Department of Fish and Wildlife Region 4 in Fresno, with Madera County serving as the implementing agency. While the project is listed as a forecast with a posted date of August 7, 2025, specific financial values, delivery schedules, and federal procurement clauses are not provided as the agreement is a state-level environmental permit rather than a federal acquisition contract.
