Summary
With a height of 22 feet and a length of 300 feet, the dam boasts a storage capacity of 285 acre-feet and a normal storage level of 113 acre-feet. Situated on the TR-N Branch Plumbottom Creek, the dam's uncontrolled spillway width of 10 feet adds to its structural integrity.
Managed by local government authorities and regulated by the NYS DEC, Amity Lake Dam is subject to state inspection, permitting, and enforcement protocols. Despite being rated as "Not Rated" in terms of condition assessment, the dam poses a significant hazard potential and holds a moderate risk assessment of level 3. Emergency action plans have been prepared and updated, ensuring that necessary measures are in place to address potential risks and emergencies.
For water resource and climate enthusiasts, Amity Lake Dam serves as a prime example of a recreational dam that not only provides water storage and flood control benefits but also requires vigilant monitoring and management to mitigate potential risks. With its picturesque location and important role in water resource management, the dam stands as a testament to the delicate balance between human enjoyment and environmental stewardship in the face of changing climate conditions.

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.
