CONCORD, Mass. – Valve removal and v-notch weir installation at the Townshend Dam in Townshend, Vermont, will be completed under the terms of a $237,690.00 contract recently awarded by the U.S. Army Corps of Engineers, New England District.
Work will be accomplished by Edward Paige Corporation, of Norwell, Massachusetts. The contract was awarded on Sept. 20, 2018. Once a notice to proceed is issued construction will be authorized to start.
The work involves the excavation and removal of seven cast iron valves ranging in depth from 2-8 feet, which connect the relief well system to a below ground collector pipe that outlets to a small pond on the downstream side of the dam. The valves will be replaced with sections of steel free flowing pipe. In addition, the construction of a reinforced concrete outlet structure that has a central dividing wall and a v-notch weir for both of the collector pipes also will be required.
The contractor will connect the toe drain collector pipe to the new outlet structure. No other work will be required on the toe drain collector pipe, which runs parallel to the dam and outlets to the small pond. In addition to the outlet work construction, the pond will be dewatered and one-foot of material will be dredged from the area. All of the above work will take place at the toe of the dam on the downstream side.
Townshend Lake Dam on the West River in Townshend is 1,700 feet long, 133 feet high and cost $7.4 million to construct. Its lake can hold a 33,700-acre‑foot reservoir with a capacity to store 10.8 billion gallons of water. During the 1987 floods, the dam used 100 percent of its storage capacity and prevented damages of $14.2 million. Since it was placed in operation in 1961, the dam has prevented damages of $137.1 million.
The reservoir area offers recreational opportunities, including swimming, picnicking, fishing, hunting, canoeing, boating and nature study and annually attracts nearly 81,000 visitors. For more information on recreation at Townshend Lake call (802) 365-7703 or visit the website at
