About Lock 24 Dam Erie Canal
The primary purpose of Lock 24 Dam Erie Canal 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 New York State Canal Corporation (state). It impounds the Seneca River near Baldwinsville.
The dam stands 21 feet tall and stretches 325 feet across, creates a reservoir covering 313 acres, has a maximum storage capacity of 35,000 acre-feet, and collects water from a drainage area of 3,266 square miles. Completed in 1908, the structure is over a century 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 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 12/14/2021.
