National Program for Inspection of Non-Federal Dams. Reservoir Number 3 Dam (MA 00691), Thames River Basin, Southbridge, Massachusetts. Phase 1 Inspection Program
Reservoir No.3 Dam is approximately 490 feet long excluding the spillway and has a maximum height of approximately 24 feet. It consists of an earth embankment with riprap at the upstream face and a loamed and seeded crest and downstream face. A gatehouse is present at the center of the dam just upstream of the face of the crest. The 45 foot wide masonry spillway is located at the left abutment of the dam. The facility is considered in fair condition. This classification is based on the observation of surficial sloughing at the downstream face and seepage at the embankment downstream toe. Hydrologic analysis indicates that the spillway and emergency overflow capacity with the water surface at the top of the dam is approximately 890 cfs, which is greater than the total routed test flood outflow of 785 cfs. The estimated test flood stage is about 0.5 feet below the nominal top of dam. Recommended remedial measures include the filling of animal burrows, the clearing of weeds, brush and debris from the downstream channels, the limiting of vehicle traffic on the dam, and the repair of minor deterioration at the spillway.
