National Program for Inspection of Non-Federal Dams. New Naugatuck Reservoir Dam (CT 00307), Housatonic River Basin, Bethany, Connecticut. Phase I Inspection Report
The New Naugatuck Reservoir Dam, built in 1914, consists of an earth fill embankment with a concrete corewall, a spillway and spillway channel with an earth fill embankment dike. The dam is 790 feet long including the spillway. The top of the dam (elevation 540.8) is 20 feet wide and is 80 feet above the streambed of Beacon Hill Brook. The corewall has a top elevation of 537.8 or 3 feet below the top of the dam. The spillway, located at the left end of the dam, is 40.5 feet long at the crest and consists of a concrete ogee weir and a stone paved discharge channel. The dike is 310 feet long, 10 feet high and 10 feet wide at the top. The outlets are a 16 inch upper level outlet at the left side of the dam near the toe of the dike and a 12 inch low-level outlet at the downstream toe of the dam. Based upon the visual inspection at the site and past performance, the dam is judged to be in good condition. No evidence of instability was observed in the dam or dike embankments. The condition of the spillway and outlet channels appear to be good. There are areas requiring attention and monitoring such as seepage along the downstream toe of the dam embankment. The spillway capacity with the reservoir level to the top of the dam is 2,130 cfs, which is 51% of the routed test flood outflow.
