Summary

Completed in 1904, this masonry dam stands at a height of 21 feet and spans 250 feet in length, offering a serene surface area of 4 acres for outdoor enthusiasts to enjoy. The dam's primary purpose is for recreation, providing a maximum storage capacity of 14 acre-feet and a normal storage level of 12 acre-feet for the surrounding community.

Despite its historical significance and recreational value, Beechmont Lake Dam is facing some challenges in terms of its condition assessment. The dam has been rated as in poor condition, with a significant hazard potential. The most recent inspection in November 2020 identified the dam's condition as needing attention, highlighting the importance of regular maintenance and potential risk management measures to ensure the safety and integrity of the structure.

With its location along the PINE BROOK river and under the jurisdiction of the NYS DEC, Beechmont Lake Dam is a prime example of the intersection between water resource management and climate resilience. As a key part of the local infrastructure, efforts to address the dam's condition and implement necessary improvements will be crucial in safeguarding both the recreational benefits it provides and the surrounding ecosystem.

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.
