National Program for Inspection of Non-Federal Dams. Seymour Reservoir Number 3 Dam (CT 00323), Naugatuck River Basin, Oxford, Connecticut. Phase I Inspection Report
The Seymour Reservoir No. 3 Dam consists of an earth embankment with a masonry core wall. The embankment has a top width of 14 feet and a maximum height of 42 feet. The overall length of the dam is 730 feet, including 23.5 foot long concrete overflow spillway. The outlet works consist of a 12-inch cast iron low level outlet or blowoff pipe through the earth embankment and core wall. The dam impounds the Seymour No. 3 Reservoir, a storage reservoir for public water supply for the Valley Division of the Bridgeport Hydraulic Company. Based on the visual inspection and a review of all available pertinent data, the dam is considered to be in fair condition. Features that could affect the structural integrity of the dam are undermining and seepage associated with the left wall of the spillway discharge channel; uncontrolled seepage that bypasses the underdrain; and the absence of an upstream gate on the low level outlet or blowoff line. The spillway can discharge 132 percent of the routed Test Flood outflow with flashboards and 151 percent without flashboards. The Test Flood would not overtop the dam.
