Summary
This concrete arch dam stands at a height of 30 feet and has a length of 75 feet, with a storage capacity of 8 million gallons. While the primary purpose of the dam is water supply, it also plays a role in flood control and environmental protection along the TR-PIKE BROOK.
Despite its significant hazard potential and poor condition assessment, Pike Brook Dam undergoes regular inspections and enforcement by the New York State Department of Environmental Conservation (NYS DEC). The dam is regulated, permitted, and inspected by the state, ensuring its safety and functionality. With a spillway width of 75 feet and uncontrolled spillway type, the dam is equipped to handle potential overflow events and protect surrounding areas.
Climate and water resource enthusiasts will find Pike Brook Dam to be a fascinating structure, showcasing the intersection of engineering, environmental protection, and public safety. With its historical significance and ongoing maintenance efforts, the dam serves as a crucial piece of infrastructure for both water supply and flood control in the region, under the regulatory oversight of the NYS DEC.

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.
