National Program for Inspection of Non-Federal Dams. Farm Brook Dam (Site 1) (CT 00657), Connecticut Coastal Basin, Hamden, Connecticut. Phase I Inspection Report
The 1,210-foot-long and 11-foot-high dam was designed by the U.S. Department of Agriculture Soil Conservation Services and constructed by the Nutmeg Construction Company in 1973 as part of a flood control program in the Farm Brook watershed. The impoundment is used to form a flood control pool but also serves as a recreational facility. The dam consists of two earthfill embankments and a principal and emergency spillway. Embankment No. 1 is 535 feet long, and embankment No. 2 is 580 feet long. A 35-foot wide grass-lined emergency spillway separates the two embankments. The principal spillway, located at the midsection of embankment No. 2, is a drop inlet structure. Based on the visual inspection of the site and the past performance of the dam, the facility is judged to be in fair condition. No evidence of instability was noted in the dam or appurtenant structures. Areas requiring monitoring and maintenance include the discharges from the toe drain outlets, the infiltration of fines into the toe drain system, toe drain outlets, wet areas on the toe of embankment No. 2, and displaced riprap on the slopes of the principal spillway discharge channel. The combined capacity of the spillways, with the water surface at the top of the dam, is 610 cfs or 156 percent of the routed test flood outflow.
