Oeste Basins Groundwater Recharge Project

The Oeste Basins Groundwater Recharge Project, managed by the Mojave Water Agency, involves the development of two groundwater recharge basins measuring 3.1 and 3.3 acres. The project is located on a 10-acre vacant parcel on the south side of Cayucos Drive in Pinon Hills, San Bernardino County, California, with additional basin piping extending into a 0.03-acre California Department of Water Resources right-of-way. The primary objective is to draw between 3,400 and 5,600 acre-feet per year of State Water Project water from the California aqueduct during wet years to facilitate groundwater recharge and storage within the Oeste groundwater subbasin. The project has undergone environmental review under CEQA, resulting in a Negative Declaration indicating no significant environmental impacts, and no mitigation measures or monitoring plans were adopted. This permanent project is a refined version of the earlier Oeste Demonstration Project. The forecast for this work is categorized under NAICS code 237990, and the primary point of contact is the Senior Principal Hydrogeologist for the Mojave Water Agency.
