Abstract:

Perch Pond Dam is a composite earthfill-masonry structure, consisting of an earthfill embankment located between two dry stone masonry walls. The upstream wall is covered with concrete on the lake side of the wall. The dam is 165 feet long and 13.5 feet high. The crest is 16 feet wide, including the masonry walls. The spillway is a 12.7 foot long broad crested weir with a center pier that is 2.1 feet wide. The outlet works for the dam is an 8-in. cast iron pipe through the dam. Details of the inlet and the operational status of the outlet works could not be determined. Perch Pond Dam is judged to be in good structural condition, based on the visual inspection. Since the spillway cannot pass the 100-year flood without overtopping the dam, the spillway is rated as inadequate.
