Summary
The dam stands at a height of 24 feet and stretches 175 feet in length, with a storage capacity of 238 acre-feet. Situated on the Brantingham Lake Outlet, the dam plays a crucial role in managing water resources in the area, with a maximum discharge capacity of 700 cubic feet per second.
Despite its significant hazard potential, Adirondack Acres Dam A has been assessed as being in satisfactory condition, with a moderate risk rating of 3. The dam is regulated by the New York State Department of Environmental Conservation (NYS DEC) and undergoes regular inspections every four years to ensure its structural integrity and safety. In the event of an emergency, the dam owners are expected to have an Emergency Action Plan (EAP) in place, although details about its preparedness and compliance are not specified in the available data.
For water resource and climate enthusiasts, Adirondack Acres Dam A serves as a vital structure within the Lewis County region of New York, providing recreational opportunities while also posing potential risks that require careful monitoring and management. With its controlled spillway and significant storage capacity, the dam plays a crucial role in water management and flood control along the Brantingham Lake Outlet. As climate change continues to impact water resources, the maintenance and upkeep of dams like Adirondack Acres Dam A are essential for ensuring the safety and sustainability of the surrounding environment.

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.
