The dam is 10.5 foot high stone masonry gravity structure. It is approximately 83 feet long, consisting primarily of a masonry spillway selection with a stone training wall to the right and a tiered stone training wall to the left. It appears that Pameacha Avenue, to the left of the spillway, is on what was formerly a dam embankment. However, filling on the downstream side of Pameacha Avenue for a parking lot, has obscured the original configuration of the project. There is an abandoned low-level intake structure on the upstream side of Pameacha Avenue. The spillway is constructed of uncut to extremely rought cut, dry laid stone masonry with an 18-in. concrete cap. The downstream face of the spillway is steeped and the approach channel is shallow with a silty bottom. For a length of approximately 19 feet near its left end, the spillway crest has been lowered by about 2 feet. There is no concrete cap and the crest elevation is very irregular in this area. Based upon the visual inspecton, the project is in poor condition. The following features could influence the future condition andor stability of the project 1 Significant deterioration of the masonry spillway and left training, wall, inlcuding irregularities in the crest and downstream face and displacement of many stones 2 Seepage from the downstream face of the masonry spillway especially near the right end 3 Several large trees and much brush growing from the downstream face of the spillway and form near the right and left spillway training walls 4 Erosion of the channel bank across the stream from the spillway 5 The low-level outlet is not operable.
