National Program for Inspection of Non-Federal Dams. Burr Pond Dam (CT 00099), Farmington River Basin, Torrington, Connecticut. Phase I Inspection Report.
Abstract
The Burr Pond Dam consists of a stone masonry wall with an upstream earth embankment. The dam has a maximum height of 17 feet and an overall length of 170 feet, including a 44.7-foot-long overflow spillway located near the center of the dam and auxiliary spillways located on each side of the amin spillway with a total length of 50.5 feet. The outlet works consist of a 6-inch cast iron high level outlet and an 18-inch corrugated metal low level outlet or blowoff controlled by manually operated gates in a gate chamber at the left end of the main spillway. The dam impounds Burr Pond, a portion of Burr Pond State Park and is used for swimming, fishing and boating. Based on the visual inspection, the dam is judged to be in fair condition. Features that can affect the integrity of the dam are the seepage through the left side of the dam, erosion of the upstream slope of the dam, possible development of internal erosion along the root systems of trees near the downstream toe of the dam, and the poor condition of the low level outlet or blowoff pipe. The Test Flood inflow is 1,425 cfs and the routed outflow of 720 cfs results in a freeboard from water surface to the top of the dam of 1.2 feet. The spillway capacity with the water level at the top of the dam is 1,415 cfs and is equal to 197 percent of the routed Test Flood outflow.
