Completed in 1968, this Earth-type dam stands at a height of 10 feet and spans 300 feet in length, with a storage capacity of 117 acre-feet and a surface area of 23.3 acres. The dam is state-regulated and has been inspected as recently as May 2016, with a satisfactory condition assessment.
Despite its significant hazard potential, the dam is currently assessed as being in satisfactory condition. With a drainage area of 0.43 square miles, the dam serves as a critical habitat for fish and wildlife in the region. The presence of an uncontrolled spillway and other controlled outlet gates ensures proper management of water levels and mitigates the risk of flooding. Lemanquais Pond Dam represents a crucial piece of infrastructure for water resource management and conservation efforts in the area, contributing to the overall ecological health of the West Branch of the Farmington River.
