Proposed Watsonville/Struve Slough Diversion with Recharge Basin Project
The Watsonville Slough system, of which Struve Slough is a component, is a network of approximately 800 acres of coastal salt marsh, seasonal wetlands, brackish and freshwater emergent marsh, and riparian communities. It receives runoff from a 13,000-acre watershed. The proposed project is to utilize some of the available freshwater supply that would otherwise drain to Monterey Bay.
The project approach and design are similar to the Harkins Slough Facilities, including diversion, filtration, and recharge facilities. This proposed project would divert water during times of high flows, approximately November through May. The water would be stored in the shallow aquifer located on the San Andreas Terrace and then recovered as needed through a series of extraction wells and used as an alternative to groundwater for agricultural irrigation to help stop seawater intrusion and balance our overdrafted groundwater basin.
