Abstract:

The dam is approximately 18 feet high and 250 feet long. The spillway which comprises the main dam section is a stone masonry gravity section with a 5 foot high dike to the left and concrete intake structure to the right. The 100-foot-long spillway is constructed of uncut to extremely rough cut, dry-laid stone masonry with a 6 foot wide concrete cap. The masonry is at a batter of 5 vertical to 1 horizontal on the downstream side and the spillway approach channel slopes sharply and has a silt, sand, and gravel bottom. Based upon the visual inspection, the project is in poor condition. The following items could influence the future condition andor stability of the project 1 There is substantial seepage emanating from the downstream face of the masonry spillway section 2 The sluice gates in the intake structure at the right end of the dam area inoperable 3The left intake channel wingwall has become separated from the gate structure, leaving a gap of 0.4 feet between them.
