About Stewarts Bridge
The primary purpose of Stewarts Bridge 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 Brookfield Renewable Power Llc Nyro (private). It impounds the Sacandaga River near Hadley.
The dam stands 113 feet tall and stretches 1,860 feet across, creates a reservoir covering 480 acres, has a maximum storage capacity of 18,600 acre-feet, and collects water from a drainage area of 1,054 square miles. Completed in 1952, the structure is well into its service life at over 50 years old.
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 09/01/2022.
At 113 feet, this dam is taller than 98% of all dams in the United States.
