Water Regulation

Deputy Refuge Manager Cortez Rohr adjusts release gates on the Lower Red Rock Lake water control structure. Water levels at the Refuge are regulated such to provide increased hemi-marsh habitat for returning spring migrating waterfowl and shorebirds, ensure early trumpeter swan nesting success, facilitate later nesting success of ducks and geese, provide a staging area for fall migrating waterfowl, and to remain in compliance with water rights agreements.
