Document Description
The District is proposing to modify the dam apron on the Capay Diversion Dam by extending it 38 ft and resurfacing the concrete apron downstream from the toe of the dam and along the entire 450 ft length of the structure. The proposed project also includes installation of a grade control structure ~150 ft downstream of the dam that is designed to protect the dam from the potential advance of downstream erosion and the long-term streambed degradation of Cache Creek. The proposed project would not result in an increase in diversion capacity, water delivery, or transmission.
