This project consists of making improvements to existing diversion and recharge facilities owned and operated by the San Bernardino Valley Water Conservation District (SBVWCD). Improvements include adding a debris removal system and rubber dam gate at the intake and constructing a new sedimentation basin, canal, pipeline, and recharge basins to increase the amount of stormwater that can be captured and recharged from the Santa Ana River just downstream from the Seven Oaks Dam. The project will divert and recharge up to 80,000 acre-feet (AF) in a single year and 500 cubic feet per second (cfs) instantaneous flow once all phases are complete.
Phase 1 is located outside of the Upper Santa Ana Wash Land Management and Habitat Conservation Plan (WashPlan): intake improvements, sedimentation basin, and the Plunge Pool Pipeline (PPP).
This project will more than double stormwater capture and groundwater recharge capabilities below Seven Oaks Dam once completed. The improvements include installing equipment that would enable the district to remove large objects, such as rocks, boulders and trees, that can clog the existing intake channel along the Santa Ana River, which is located just downsteam from Seven Oaks Dam. The first phase of the project will result in more efficient use of the existing recharge facilities. The District will also construct additional groundwater recharge ponds during the next couple of years to increase the capture of stormwater runoff on the Santa Ana River for groundwater recharge purposes.
