The crest of the dam is 40 ft wide, and side slopes are approximately 3 horizontal to 1 vertical 31 on the upstream slope and 2.5 horizontal to 1 vertical 2.51 on the downstream slope. The principal spillway consists of a 25 ft x 10 ft reinforced concrete overflow weir box. A 24 inch diameter sluice gate in the weir box is used to lower the pool level. The spillway will pass 15 percent of the Probable Maximum Flood PMF or 150 percent of the SDF. The spillway is rated adequate.
