Seasonal Wetlands in Central Valley California are important for flood control, water quality and access, and wild life habitat. They are a vital part of the Pacific Flyway, supporting 60% of California’s migratory birds. This project aims to replace dilapidated water control structures, remove unnecessary levees, and construct new swales to better manage Blue Goose Slough, a 60-acre wetland complex in the San Luis National Wildlife Refuge. The goal is to manage the wetland as a semi-permanent or seasonally flooded hemi-marsh, depending on surface water availability. The improvements will also allow U.S.Fish and Wildlife Service staff to more efficiently irrigate and manage 215 acres of seasonally flooded areas. This project complements a recent North American Wetlands Conservation Act project on the nearby Triangle and Schwab Ponds.
