National Program for Inspection of Non-Federal Dams. Batterson Park Pond Dam (CT 00262), Connecticut River Basin, Farmington/New Britain, Connecticut. Phase I Inspection Report

摘要

The Batterson Park Pond Dam is an earthfill embankment with stone masonry core that is 1,300 feet long and 30 feet high with a 35 foot wide spillway. It has two, 20 inch blowoffs as well as a line to an adjacent fire hydrant. The dam is classified as intermediate in size and has a high hazard potential based on downstream habitation. based on visual inspection, hydraulic computations and past operational performance, the dam is judged to be in poor condition. Areas of the dam should be studied in order to monitor its behavior such as the central downstream slope which is swampy and shows considerable seepage and the deteriorated spillway channel. The drainage area contributing to the dam is 4.68 square miles. The routed test flood peak outflow (Probable Maximum Flood) is 5,295 cfs which will overtop the dam by 1.21 feet. The project will pass only 29 percent of this peak outflow before overtopping the dam.
