National Program for Inspection of Non-Federal Dams. Farm Brook Site 2A Dam (CT 01546), Connecticut Coastal Basin, Hamden, Connecticut. Phase I Inspection Report

摘要

Farm Brook Site 2A Dam, one of two dams (See Farm Brook Site 2B Dam CT-01547 Report) impounding water at the Site 2 Reservoir consists of an earth embankment approximately 440 ft. long with top width of 14 ft. and a maximum height of 29 ft. The low level outlet for the project is the principal spillway which consists of a three stage reinforced concrete intake riser, a 30-inch reinforced concrete pipe and a 16 ft. long impact basin. In addition to the low-level outlet, there is a 210 ft. wide, grassed trapezoidal channel at the dam's west end serving as the emergency spillway. Based on the visual inspection and review of available plans and reports, Farm Brook Site 2A Dam is judged to be in good condition; however, since the reservoir did not contain much impoundment at the time of inspection, any possible seepage conditions at the dam could not be ascertained. With the water level at the top of the Site 2A dam the maximum spillway capacity is 8700 cfs which is 210% of the Site 2A routed outflow. The storage capacity of the reservoir at the top of the dam is 1190 ac. ft.
