National Dam Inspection Program. Hartford Reservoir Number 2 Dam (CT 00003). Connecticut River Basin, Spice Brook, West Hartford, Connecticut. Phase I Inspection Report

摘要

The Hartford Reservoir No. 2 Dam consists of an earth embankment with a maximum height of 50 feet, a top width of 8 feet, and a total length of 1425 feet including a 54 foot long overflow spillway located at the left end of the dam. The outlet works consist of 3 cast iron pipes through the embankment, controlled by downstream gate valves. The dam impounds Hartford Reservoir No. 2, a storage reservoir for public water supply owned by the Metropolitan District, Hartford, Connecticut. Based on the visual inspection, the dam is judged to be in fair condition. Features that could affect the future integrity of the dam are downstream seepage, erosion of the slopes, the presence of trees on the slopes, and inadequate spillway capacity. The Test Flood inflow of 2,550 cfs results in a Test Flood routed outflow of 1,970 cfs that would overtop the dam by 0.1 feet. The spillway capacity is 1,540 cfs or 78 percent of the Test Flood routed outflow.
