Conklingville
Conklingville is an earth dam located in Saratoga County, New York, built in 1930. It carries a High hazard potential classification and has a satisfactory condition assessment.
About Conklingville
The primary purpose of Conklingville 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 Hudson River-black River Regulating District (state). It impounds the Sacandaga River near Hadley.
The dam stands 100 feet tall and stretches 1,100 feet across, creates a reservoir covering 25,940 acres, has a maximum storage capacity of 792,000 acre-feet, and collects water from a drainage area of 1,044 square miles. Completed in 1930, the structure is well-established, with more than 75 years of service.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 08/16/2022.
At 100 feet, this dam is taller than 98% of all dams in the United States.
