National Program for Inspection of Non-Federal Dams. Bristol Reservoir Number 2 Dam (CT 00365) Farmington River Basin, Harwinton, Connecticut. Phase I Inspection Report.
Abstract
Bristol Reservoir No. 2 is a storage reservoir for public water supply owned by the Bristol Water Department. The dam consists of an earth embankment with a top width of 10 feet, a maximum height of 33 feet and a total length of 650 feet including a 20 foot overflow spillway located near the left end of the dam. The outlet works located near the center of the dam consist of a 12-inch cast iron level outlet or blowoff through the dam controlled by a downstream gate. Based on the visual inspection, the dam is judged to be in good condition. Features that could affect future integrity of the dam are downstream seepage, trees growing adjacent to the downstream toe, the downstream location of the low level outlet or blowoff control valve, and brush in the downstream spillway channel. The Test Flood inflow of 330 cfs results in a routed outflow of 225 cfs and a freeboard of 1.2 feet. The spillway capacity with the 9-inch high flashboards in place is 430 cfs or 191 percent of the Test Flood routed outflow.
