National Program for Inspection of Non-Federal Dams. John D. Milne Dam (CT 00058). Connecticut Western Coastal Area, New Canaan, Connecticut. Phase I Inspection Report.
Abstract
The dam is a linear concrete gravity structure with a central spillway. The upstream face of the dam is vertical. The stream face is vertical for 7.5 feet below the top of the dam and then slopes of 7 horizontal to 10 vertical. The spillway is concrete with an ogee shape. Based on the visual inspection of the site, review of available information and past performance of the dam, the dam is judged to be in good condition. The spillway will pass the test flood without overtopping the dam, and therefore the spillway capacity is adequate. Additional investigations to further assess the adequacy of the dam and appurtenant structures do not appear necessary. Patching of deteriorated concrete, initiated by the owner, should be continued. Additionally, during periods of unusually high precipitation, round the clock surveillance should be provided.
