Pine Mill Dam Removal, Haverhill, New Hampshire
Stone Environmental was hired by the Connecticut River Conservancy to provide design services for the removal of the Pine Mill Dam along Clark Brook, in the Town of Haverhill, NH. The 15-foot-high by 180-foot-long concrete gravity dam was constructed c. 1928 to power an adjacent grist mill. The mill was in operation until the 1940s, when electrical power replaced water power at the facility around 1941. Since the 1940s, the dam has been in a deteriorated condition, and over time flows have undermined the dam foundation.
