Oeste Basins Groundwater Recharge Project

Oeste Basins Groundwater Recharge Project

The Project consists of the development of two groundwater recharge basins of 3.1 and 3.3 acres, respectively, within a 10-acre vacant parcel located on the south side of Cayucos Drive, approximately 0.36-mile west of Oasis Road, within Assessor’s Parcel Number (APN) 3099-081-01 with some of the associated basin piping in an adjacent 0.03-acre area within the California Department of Water Resources (DWR) right-of-way, within the unincorporated area of San Bernardino County known as Piñon Hills. Based upon anticipated infiltration rates, the Proposed Project is designed to draw approximately 3,400 to 5,600 acre-feet/year of State Water Project water from the California aqueduct in wet years for groundwater recharge and storage in the Oeste groundwater subbasin. A CEQA IS/MND for an earlier version of the project (Oeste Demonstration Project) was adopted by the Mojave Water Agency in 2024. A refined version of the project (Oeste Permanent Project) is the subject of the Supplemental IS/MND.
