National Program for Inspection of Non-Federal Dams. Kinneytown Dam (CT 00089) Naugatuck River Basin, Seymour, Connecticut. Phase I Inspection Report
The Kinneytown Dam is a run-of-the-river dam across the Naugatuck River and consists of a concrete ogee spillway section with a crest length of 413 feet. The maximum height of the dam is 32.5 feet. A railway embankment forms the left abutments and an earth embankment approximately 50 feet in length connects the right training wall to the right abutment. The low level outlet or blow-off consists of a 48-inch cast iron pipe through the left end of the spillway controlled by an upstream sluice gate. A diversion intake structure and canal located to the left of the dam and separated from the river by a railroad embankment diverts water from the impoundment to a downstream ponds, where it is used to generate electricity and for processing purposes for a downstream manufacturing plant. Based upon the visual inspection and a review of all available pertinent data, the dam is considered to be in fair condition. The erosion and undermining of the spillway apron, deterioration of the concrete of the spillway, aprons, and training walls, seepage downstream of the left training wall and through the right training wall, deterioration and lateral movement of the left sheet pile wall, and tree growth on the earth embankment require further investigation or attention. The calculated test flood outflow of 63,000 cfs would overtop the dam by 0.3 feet. The spillway capacity with the water level at the top of the dam is equal to 59,000 cfs or 94% of the test flood.
