Marble Mill, located in Dorset, Vermont, is a historic earth dam built in 1875 on the West Branch Batten Kill River. The dam stands at a height of 16 feet and spans 275 feet in length, with a storage capacity of 125 acre-feet. Primarily used for recreational purposes, this multi-arch dam presents a significant hazard potential with a poor condition assessment as of May 2020.

Despite being privately owned, Marble Mill is regulated by the Vermont Department of Environmental Conservation (DEC) for permitting, inspection, and enforcement purposes. The dam's last inspection took place in June 2017, with an inspection frequency of every three years. With its location in a beautiful natural setting and its historical significance, Marble Mill serves as a key point of interest for water resource and climate enthusiasts in the Bennington County area.
