Upper-Town Dam Final Design Plans

Final dam removal design plans for the Upper-Town Dam in Lisbon, Maine. This project removed a derelict mill dam that impounded 6 feet at water when the spillway was intact. Removal of the spill and regrading of riverbanks, restored a much wider natural channel that will remove the impounded water upstream. This project will reduce flood risk to riparian landowners that are adjacent to the former impoundment and remove the need for flood insurance for some of the those landowners.
