Wildlife Pond Dam under Reconstruction

During September 2018, the Beaver Brook Wildlife Pond Dam will be reconstructed. The earthen dam, built in 1968, is in need of repairs to maintain the safety of the dam.

In order to make repairs the pond must be emptied. Permits to do this have been obtained through the NH Department of Environmental Services (DES, Wetland Division and Dam Bureau) and every attempt will be made to have as little of an impact as possible on surrounding wildlife and vegetation.
This work is required in order to maintain the man-made Wildlife Pond as a habitat.

During construction, the public will not have access to dam or Dam Road.  Thank you for your understanding.
