Standing at 15 feet tall and 250 feet long, this concrete dam serves a primary purpose of generating hydroelectric power. With a storage capacity of 86 acre-feet and a normal storage of 52 acre-feet, Gilman Mill plays a crucial role in water resource management in the area.
Despite being classified as having a low hazard potential, Gilman Mill is subject to state regulation, permitting, inspection, and enforcement by the Maine Emergency Management Agency. The dam has not been rated for its condition assessment, with the last inspection conducted in April 2011. With a spillway width of 40 feet, Gilman Mill is equipped to handle water discharge effectively, contributing to flood control measures in the region.
Located in the New England District, Gilman Mill's operational efficiency and structural integrity are vital for sustainable water resource management and climate resilience. As a key player in the local hydroelectric infrastructure, this dam serves as a reminder of the intersection between water resources, climate adaptation, and renewable energy generation in Maine.
