Summary
Regis Falls is a privately-owned hydroelectric dam on the St. Regis River. Built in 1947, this timber crib dam stands at a height of 10 feet and has a storage capacity of 800 acre-feet. The dam serves multiple purposes including fire protection, stock maintenance, hydroelectric power generation, and recreation, highlighting its importance in water resource management and climate resilience.
Managed by the Federal Energy Regulatory Commission, St. Regis Falls has a low hazard potential and a moderate risk assessment rating. The dam features an uncontrolled spillway with a width of 94 feet and three slide-type outlet gates. Despite its age, the dam is regularly inspected and maintained, with the last inspection taking place in September 2018. The surrounding area benefits from the dam's water storage capacity, which covers a surface area of 225 acres and has a drainage area of 235 square miles, ensuring water availability for various uses in the region.
With its vital role in providing clean energy, water storage, and recreational opportunities, St. Regis Falls is a significant landmark in the water resource and climate conservation landscape of New York. The dam's presence contributes to the overall resilience of the region, with proper management and regulatory oversight ensuring its continued operation and safety. As climate change continues to impact water resources, dams like St. Regis Falls play a crucial role in supporting sustainable development and adaptation efforts in the face of environmental challenges.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
