About Lermond Pond
The primary purpose of Lermond Pond is hydroelectric. The dam generates hydroelectric power by channeling water through turbines, converting the energy of flowing water into electricity. The dam is owned by Richard Morgan (private). It impounds the Mill Stream.
The dam stands 12 feet tall and stretches 350 feet across, creates a reservoir covering 171 acres, has a maximum storage capacity of 670 acre-feet, and collects water from a drainage area of 13 square miles. Completed in 1850, the structure is one of the older dams in the region, with over a century and a half of service.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 11/15/2017.
