Summary

Completed in 1937, this concrete structure stands at a height of 14 feet and spans 93 feet in length. With a primary purpose of recreation, the dam offers a storage capacity of 132 acre-feet and covers a surface area of 30 acres. The dam is regulated by the New York State Department of Environmental Conservation (NYS DEC) and is inspected, permitted, and enforced by the state authorities.

Despite being rated as having a low hazard potential, the dam's risk assessment is categorized as very high (1), highlighting the importance of proper risk management measures. Although the last inspection dates back to 1976, the dam's condition is currently not rated, and there is no Emergency Action Plan (EAP) in place. The Beaver Meadow Brook Dam plays a crucial role in the local community, providing recreational opportunities while also presenting a potential risk that requires ongoing monitoring and management to ensure public safety and environmental protection.

With its picturesque location in Number Four, New York, along the Beaver Meadow Brook, this dam serves as a valuable asset for the region. As enthusiasts of water resources and climate, it is essential to recognize the significance of maintaining and monitoring dams like Beaver Meadow Brook to mitigate potential risks and ensure sustainable water management practices in the face of changing environmental conditions.

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.
