Summary
Constructed in 1925, the dam stands at a height of 16 feet and has a length of 230 feet, providing a storage capacity of 475 acre-feet. The dam regulates Pine Lake Brook, with a drainage area of 1.3 square miles and a surface area of 75 acres.
Managed by the local government and regulated by the NYS DEC, Pine Lake Dam & Dike has a low hazard potential and a moderate risk assessment rating. The spillway, with a width of 160 feet, is uncontrolled, and the dam has not been assessed for its current condition. Despite not having a formal Emergency Action Plan (EAP) in place, the dam meets inspection, permitting, and enforcement requirements, ensuring the safety of the surrounding community and the water supply.
With its historical significance and vital role in water supply management, Pine Lake Dam & Dike serves as a critical infrastructure in the region. As climate change impacts water resources, the maintenance and monitoring of such structures become increasingly important to ensure resilience and sustainability 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.
