National Program for Inspection of Non-Federal Dams. Stodge Meadow Pond Dam (MA 00009), Merrimack River Basin, Ashburnham, Massachusetts. Phase I Inspection Report.
Abstract
Stodge Meadow Pond Dam is formed by an approximately 250 ft. long earth embankment which has a maximum height of 15 ft. A conduit spillway controlled by an overflow weir with stoplogs and a gated outlet conduit are both appurtenant to the dam. The dam is over 100 years old, except for the conduit spillway, which was constructed in 1977. The pond has a maximum storage capacity of about 900 acre-ft. and is used for recreational purposes by the surrounding group of property owners, who collectively own the pond and dam. The dam is in good condition, based on a visual examination of the structure. Although some deficiencies were noted, there was no evidence of settlement, lateral movement or other signs of structural failure or other conditions which would warrant urgent remedial action. With the water level at the top of the dam, the ungated spillway capacity is 325 cfs. Hydraulic analyses indicate that the test flood outflow of 240 cfs (inflow 605 cfs or 2,600 csm) can be passed with a freeboard of 0.4 ft. and an unused surcharge-storage of 210 acre-ft. remaining.
