National Dam Inspection Report. Easton Reservoir Dam (CT 00020), Connecticut Western Coastal Area, Mill River, Easton, Fairfield County, Connecticut. Phase I Inspection Report
The Easton Reservoir Dam is a gravity concrete dam, built in 1926. The dam section is 1,040 feet long with a maximum height of 123 feet. The top of the dam is 12 feet wide. The downstream side slopes are 0.7 horizontal to 1 vertical. The upstream slope is 0.05 horizontal to 1 vertical. The spillway is 100 feet long, with an Ogee crest. Based on the visual inspection of the site, review of available information, and the past performance of the dam, the dam is judged to be in good condition. The concrete surface has deteriorated and major spalling has occurred. Some dampness was noted at the joints. The maximum spillway capacity, at top of dam, is about 25 percent of the peak outflow rate of the test flood. The peak rate of discharge from the test flood will overtop the dam by 2.5 feet. Concrete surfaces of the downstream face and top of dam affected by spalling should be repaired by the owner. A definite plan for around the clock surveillance should be implemented during periods of unusually heavy rains and a formal warning system should be developed for use in the event of an emergency.
