National Program for Inspection of Non-Federal Dams. Gardner Lake Dam (CT 00512), Thames River Basin, Bozrah, Connecticut. Phae I Inspection Report.
Abstract
Gardner Lake Dam is an earth embankment with a shallow concrete wall that extends nearly across the full length of the upstream face. The dam is about 168 ft. long and is about 9.6 ft. high. The dam has two concrete spillways. The regulating outlet is controlled by a 3 ft. square sluice gate. The dam is judged to be in fair condition. There was no evidence of seepage and the dam appeared to be generally well maintained. There are cracks in the concrete approach training walls of the service spillway, and the embankment just right of the right training wall showed signs of settlement. Voids were also evident adjacent to both approach training walls. The combined auxiliary spillway and outlet structure, reconstructed in 1969, was found to be in good condition, but there appeared to be erosion of the earth embankment immediately down stream of the structure. Brush growth was noted on a small berm along the rim of the reservoir to the left of the dam and in the discharge channel of the auxiliary spillway. There was on lare elm tree on the dam embankment. The routed test flood outflow of 1,000 cfs overtops the non-overflow sections of the dam by 1.15 ft. The spillways can pass 235 cfs or about 34 percent of the routed test flood outflow without overtopping the dam.
