Summary
This earth dam stands at a height of 32 feet and has a length of 550 feet, providing storage capacity of 108 acre-feet. The dam is situated on the TR-MOHAWK RIVER and is regulated by the New York State Department of Environmental Conservation (NYS DEC).
With a spillway width of 15 feet and uncontrolled spillway type, the dam's hazard potential is considered significant, although its condition assessment is currently rated as satisfactory. The dam undergoes inspections every 4 years, with the last assessment conducted in June 2019. In case of emergencies, the dam's Emergency Action Plan (EAP) is being regularly updated to ensure its alignment with safety guidelines.
For water resource and climate enthusiasts, the Little Falls Dist Reservoir Dam offers a fascinating glimpse into the critical infrastructure that supports water supply in the region. Its strategic location, design features, and regulatory oversight by the NYS DEC highlight the importance of maintaining and ensuring the safety of such essential structures in the face of changing environmental conditions.

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.
