National Program for Inspection of Non-Federal Dams. Ashley Reservoir Dam (New Lower) (MA 01062) Housatonic River Basin, Washington, Massachusetts. Phase 1 Inspection Report
Ashley Reservoir Dam is an earth embankment dam approximately 250 feet long and 33 feet high. The embankment has a top width of 12 feet with 2 1/2 H to 1V upstream slopes and 2H to 1V downstream slope. There is a 5-foot wide berm with a 3-foot wide stone gutter on the downstream slope. Between the berm and the downstream toe, the slope flattens to 2 1/2 H to 1V. There is a 70-foot long concrete overflow spillway. The spillway crest is 5 feet lower than the top of dam. Based on the visual inspection, the overall condition of the dam is fair. Spillway capacity with water at the elevation of the existing low points in the top of dam is 1700 cfs which is 57% of the test flood outflow.
