The dam is a concrete on-stream dam. The dam is 366 ft. long and 19 ft. high. The dam is assessed to be in overall fair condition. The principal concern is the apparently high overtopping potential and the apparently high risk of dam failure during such an event. There is a need to perform a more detailed hydrological study due to te large watershed area, the many dams upstream, and the nature of the downstream channel. Author
