Lyman Pond Dam

Located in Southampton, the MA Office of dam Safety classifies the Lyman Pond Dam as a Significant hazard dam in Unsafe condition. The dam’s removal would eliminate the threat of failure on adjacent infrastructure. Once complete the project will also reconnect over 27 miles of a certified Coldwater Fishery Resource and improve habitat for rare mussels and the eastern box turtle.

The project continues to advance toward construction. The Town of Southampton recently received funding to relocate the Town water main that crosses the river just upstream from the Lyman Pond Dam. DER contributed funding and technical support to the water main relocation design and permitting. Meanwhile permits are accumulating for the removal of the dam, which is privately owned. Depending on the success of partner fundraising, we are anticipating a dam removal in 2020. DER has received funding from the National Fish and Wildlife Foundation and USFWS to support this project.
