About Heald Pond
The primary purpose of Heald 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 Lovell (local government). It impounds the Mill Brook.
The dam stands 12 feet tall and stretches 20 feet across, creates a reservoir covering 101 acres, has a maximum storage capacity of 800 acre-feet, and collects water from a drainage area of 5 square miles. Completed in 1860, the structure is one of the older dams in the region, with over a century and a half of service.
This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life.
