Summary

This earth dam stands at a height of 13 feet and spans 250 feet in length, with a storage capacity of 15 acre-feet. The dam overlooks the picturesque TR-Pine Brook river and covers a surface area of 2 acres, providing an ideal spot for outdoor activities and relaxation.

Despite its historical significance and recreational value, Paine Lake Dam poses a significant hazard potential and has been rated as being in poor condition. The dam is under state regulation by the NYS DEC, with regular inspections conducted to monitor its safety and structural integrity. The dam's spillway type is uncontrolled, with a spillway width of 15 feet to manage maximum discharge of 480 cubic feet per second.

In light of its poor condition assessment and significant hazard potential, stakeholders and local government authorities must prioritize maintenance and risk management measures for Paine Lake Dam. With its moderate risk rating and outdated emergency action plan, efforts should be focused on improving safety protocols, conducting necessary repairs, and ensuring compliance with regulatory standards to protect both the dam's structural integrity and the surrounding environment from potential risks and hazards.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
