Summary
Completed in 1957, this dam serves primarily for recreational purposes, providing a storage capacity of 330 acre-feet and covering a surface area of 60 acres. With a height of 13 feet and a length of 110 feet, the dam holds significant hazard potential but has been assessed as satisfactory in condition.
Managed by the New York State Department of Environmental Conservation (NYS DEC), Sage Pond Dam is regulated, permitted, inspected, and enforced by state authorities. The spillway of this uncontrolled dam is 20 feet wide, with a maximum discharge capacity of 350 cubic feet per second. Although the dam has a moderate risk level, with a risk assessment rating of 3, it meets guidelines for emergency action plans, although further updates may be needed to ensure preparedness in case of potential inundation.
Water resource and climate enthusiasts will find Sage Pond Dam an intriguing site for its historical significance, recreational value, and risk assessment considerations. Located on Beaverdam Brook and part of the Buffalo District, this dam presents opportunities for outdoor activities and serves as a vital structure for water management in the region. As discussions around climate change and infrastructure resilience continue, Sage Pond Dam's condition and risk management measures will be important topics for further exploration and monitoring by relevant authorities and stakeholders.

Dam Data Reference
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.
