Document Description
The proposed project includes improvements to the Sweetwater Dam and South Dike to safely pass and contain storm water flows associated with a Probable Max Flood event. In order to achieve that primary objective, an existing parapet wall on the north side of the dam would be raised and a new parapet wall would be constructed on the south side. Additionally, the South Dike would be raised. Other minor repairs and modifications to the Sweetwater Dam, South Spillway, and associated facilities would also be conducted. The proposed project would fully comply with the DWR Division of Safety of Dams regulatory program (California Water Code Division 3, Dams and Reservoirs).
