About Mill Pond
The primary purpose of Mill 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 Smith Mfg. Co. (private). It impounds the Lemon.
The dam stands 8 feet tall and stretches 61 feet across, creates a reservoir covering 85 acres, has a maximum storage capacity of 108 acre-feet, and collects water from a drainage area of 8 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. The most recent inspection on record was 01/29/2008. That was over 18 years ago.
