The dam is a 26.5 ft. high, 665 ft. long earth embankment dam with a concrete spillway and a manually operated main drain. It is in generally poor condition. Indications of seepage were observed under the headwall at the outlet structure and near the downstream toe. The size is intermediate with a hazard potential of high. The upstream vertical masonry wall on the left side of the spillway and the masonry headwall at the toe of the dam have experienced some misalignment. Author.
