Summary

The dam, constructed of concrete, spans 50 feet in length and reaches a height of 15 feet, creating a reservoir with a surface area of 9 acres. Despite its recreational significance, the dam is marked by a significant hazard potential and poor condition assessment, underscoring the need for regular inspections and maintenance to ensure its safety and functionality.

Managed by the New York State Department of Environmental Conservation, Pine Lake Dam is subject to state regulation, permitting, inspection, and enforcement. The dam's spillway, classified as uncontrolled with a width of 10 feet, poses a potential risk in the event of high water levels. Despite the moderate risk assessment, the dam lacks an Emergency Action Plan (EAP) and updated emergency contacts, highlighting the importance of preparedness and risk management measures for the surrounding community.

As water resource and climate enthusiasts, understanding the intricacies of Pine Lake Dam's structure and condition is vital for safeguarding both the local environment and community. With a notable hazard potential and poor condition assessment, proactive measures such as regular inspections, maintenance, and the development of an EAP are essential to ensure the safety and resilience of this critical infrastructure in the face of potential risks and emergencies.

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.
