The Enhanced Recharge project is located on the Santa Ana River and will divert up to 500 cubic feet per second (cfs). The project is estimated to recharge on average 15,500 AFY or up to approximately 80,000 AFY of stormwater during a wet year. Water will be temporarily captured at the Seven Oaks Dam and diverted stormwater will flow to recharge basins for recharge into the San Bernardino Subbasin. Phase 1B includes modification to basin structures and improvements to sediment management as part of the Enhanced Recharge project and is expected to increase capture by 3,692 AFY. This project improves the regional drought resilience due to the capture and storage of wet-year flow in the groundwater basin for use during future dry years. The project also helps improve the water quality of the groundwater basin, specifically by diluting salts and nutrient increases resulting from the recycled water projects discussed above. Habitat will be restored and protected within this project area for three federally and state listed as endangered species: the San Bernardino kangaroo rat, and the Santa Ana River woolly-star and slender-horned spineflower (two plant species).
