Feasibility Study for Raising the Level of Lake Massabesic by One Foot Ongoing
June 10, 2025
The State of New Hampshire Department of Environmental Service (NHDES) is working closely with the Manchester Water Works and the Turner Group to evaluate the feasibility of raising the dam spillway of Lake Massabesic by one foot.
The purpose of this project is to provide the ability for the lake to store more drinking water for potential future use by New Hampshire communities impacted by drinking water contamination.
Impacts to private property owners and infrastructure are currently being assessed to determine what modifications may be necessary to address potential flooding impacts.
