National Program for Inspection of Non-Federal Dams. Seymour Reservoir Dam Number 2 (CT 00324), Naugatuck River Basin, Oxford, Connecticut. Phase I Inspection Report
The Seymour Reservoir No. 2 Dam consists of an earth embankment with a masonry core wall. The dam is approximately 900 feet long with a top width of 10 feet and a maximum height of 31 feet. A 25.75 foot long concrete overflow spillway is located near the right end of the dam. The outlet works consist of a 12-inch cast iron low level outlet or blowoff pipe through the embankment, controlled by a downstream gate valve. In addition to the main dam, a low dike is located on the right side of the reservoir. The earth dike is approximately 800 feet long with an average height of 6 feet and a top width of 15 feet. Based on the visual inspection and a review of all available pertinent data, the condition of the dam is judged to be fair. The future integrity of the dam can be affected by deterioration of the floor of the spillway channel; seepage exiting downstream of the dam; the absence of an upstream gate on the low level outlet or blowoff line; and inadequate spillway capacity. The spillway has a capacity of 500 cfs without any flashboards and 100 cfs with flashboards before overtopping the low point of the dam crest. With flashboards, the spillway can pass 18 percent of the routed Test Flood outflow. Without any flashboards the spillway can pass 91 percent of the routed Test Flood outflow and the outflow would overtop the low point of the dam crest by 0.2 feet.
