National Program for Inspection of Non-Federal Dams. Cedar Swamp Pond Dam (MA 00628), Charles River Basin, Milford, Massachusetts. Phase 1 Inspection Report
Cedar Swamp Pond dam, which was constructed in 1939, consists of an 11 foot high concrete spillway combined with an 8 foot high earthfill embankment. The concrete ogee-type spillway is about 100 feet long. The outlet control is comprised of two 4-foot square steel slide gates located in the left abutment of the spillway section. Based on the visual inspection, drawings available for the dam, and past operational performance, it is judged that Cedar Swamp Pond Dam is in good condition. However, there are a number of problems which should be corrected. These include: local erosion of the dam slopes, large trees on the dam embankment, spalling of the spillway concrete, and an accumulation of weeds, soil, and debris in the downstream channel. It was also noted that the access plates to the flashboards on the spillway deck are welded shut. Hydraulic analyses indicate that the existing spillway can discharge a flow of 2,840 cubic feet per second (cfs) at Elevation (El) 272.5 which is the minimum top of the dam. The spillway is adequate to discharge the inflow test flood of 3,513 cfs (one-half of the probable maximum flood) without significantly overtopping the main dam.
