Abstract:

The Pin Shop Pond Dam consists of an earth embankment with a 100 fokot long stone masonry overflow spillway located at the left end of the dam. Teh dam has a total length of 400 feet and a miximum height of 23 feet. The outlet works located to the left of the spillway consistk of an intake sluice gate which discharges into a stone masonry and concrete structure. A 16-inch gate valve drains the structure and discharges downstream of the spillway, A conduit to a downstream industrial complex is plugged with concrete. Based on the visual inspection, the dam is judged to be in poor condition. The future integrity of the dam can be affected by the lack of slope protection on the upstream slope, and continued erosion of the upstream and downstream slopes trees on the embankment continued undermining of the spillway apron vegetation growing in open joints of the stone masonry training walls the poor condition of the outlet works and indagequate spillway capacity. The spillway has a capacity of 3,200 cfs and is capable of discharging 34 percent of the Test Flood outflow.
