National Program for Inspection of Non-Federal Dams. Laurel Lake Dam (CT 00372), Connecticut River Basin, New Hartford, Connecticut. Phase I Inspection Report
The Laurel Lake Dam is an earth embankment built about 1965 and impounding an unnamed tributary to Morgan Brook in New Hartford, Connecticut. The dam is approximately 595 feet long, 10 feet wide at the top, 27 feet high and has a maximum impoundment of 176 acre-feet. The spillway is a 40 ft. long unlined earth channel located at the left end of the dam. A 24 inch cast iron drop inlet pipe is located approximately 10 feet upstream from the central portion of the dam. A 30 inch x 30 inch steel frame structure with removable boards is used to control the lake level. No low-level outlet was found at the dam. The outlet is a 24 inch concrete pipe. The slopes and top of the dam are densely vegetated with brush and tree saplings. A footpath extends the entire length of the dam crest. Based upon visual inspection at the site and past performance of the dam, the project is judged to be in poor condition. There are areas requiring maintenance, monitoring and repair such as seepage, embankment repair, lack of proper spillway protection and vegetation on the embankment. Based upon hydraulic computations, the spillway capacity is 410 cfs, which is greater than 100% of the routed test flood outflow.
