National Program for Inspection of Non-Federal Dams. Dooley Pond Dam (CT 00142), Connecticut River Basin, Middletown, Connecticut. Phase I Inspection Report
The project, substantially reconstructed in 1967, has a total length of approximately 320 feet, consisting of an approximately 300 foot long embankment and a 20 foot long concrete spillway. The dam is approximately 23.5 feet in height above the streambed of Long Hill Brook and, with the pond level to the top of the dam, impounds approximately 250 acre-feet of water. The upstream slope is protected to the top of the dam by dumped rock riprap. The spillway is a concrete chute and is located near the right end of the dam. The low-level outlet facility is a 24 inch reinforced concrete pipe at the central portion of the embankment and is controlled from a concrete gatehouse on the dam. Based upon visual inspection and past performance, the project is judged to be in fair condition. No evidence of instability of the embankment or spillway was observed. However, there are items which require monitoring and/or maintenance, such as erosion of the spillway discharge channel and a stagnant water condition in the low-level outlet channel which does not allow a free flow of water from the toe drain pipes. Peak inflow to the reservoir at the 1/2 PMF is 850 cubic feet per second (cfs); peak outflow is 580 cfs with the lowest point along the top of the dam overtopped by 0.4 feet. The spillway capacity, with the reservoir level to the low point of the top of the dam, is 380 cfs, which is equivalent to 66% of the routed test flood outflow.
