National Program for Inspection of Non-Federal Dams. Mare Meadow Reservoir Dam (ME 01020), Connecticut River Basin, Hubbardston, Massachusetts. Phase 1 Inspection Report
Mare Meadow Reservoir Dam was constructed in 1954. The structure is an earth embankment with a concrete core wall approximately 830 feet long and 46.5 feet high. The spillway is a 1,100 foot long vegetated trapezoidal channel constructed by excavating a natural saddle approximately 2,000 feet to the east of the dam. The outlet works consists of an intake structure within the reservoir from which two 20 inch pipelines pass through the dam, one of them outletting near the downstream toe and the other continuing on to a pump station. The facility is considered in fair condition. Seepage in the form of a spring near the downstream toe and flow along the 20 inch reservoir drain pipe were observed. The spring is reported to be from the discharge of the dam drainage system while the flow along the reservoir drain is reported to be from ground water from the right valley slope. The spillway capacity is adequate for the selected routed test flood outflow with 2.9 feet of freeboard remaining at the dam. Recommended remedial measures include the removal of brush and trees from the embankment and spillway, the limiting of vehicle traffic on the crest, the filling of animal burrows, and the removal of silt and vegetation from the spillway channel.
