National Program for Inspection of Non-Federal Dams. Seymour Reservoir Number 1 Dam (CT 00358), Naugatuck River Basin, Beacon Falls, Connecticut. Phase I Inspection Report.
Abstract
The Seymour Reservoir No. 1 Dam consists of an earth embankment with a stone masonry core wall. The dam has an overall length of 340 feet including spillway; a top width of 10 feet; and a maximum height of 26 feet. The overflow spillway consists of a 23-foot concrete weir with stone masonry training walls. The outlet works consist of two 12-inch cast iron pipes through the earth embankment and core wall of the dam, controlled by manually operated gates in an upstream gage house. Based on the visual inspection and review of all pertinent data, the condition of the dam is judged to be fair. Features that can affect the integrity of the dam are the deterioration of the spillway weir, the seepage exiting at the toe and downstream of the dam, and inadequate spillway capacity. Due to the small size of the impoundment, the Test Flood outflow was assumed to equal the Test Flood inflow of 625 cfs and would overtop the low point of the dam crest by 0.9 feet. The spillway capacity with the water level at the low point of the dam crest is equal to 105 cfs or 17 percent of the Test Flood.
