Summary
Completed in 1990, this earth dam stands at 13 feet high and stretches 350 feet in length, providing a storage capacity of 38 acre-feet. With a significant hazard potential, the dam is regulated by the New York State Department of Environmental Conservation, ensuring regular inspections and enforcement to maintain its structural integrity.
The dam features an uncontrolled spillway with a width of 30 feet and a maximum discharge capacity of 1390 cubic feet per second. Despite being classified as having a moderate risk level, the dam's condition assessment is currently not rated. The last inspection conducted in August 2018 revealed the need for a more frequent inspection schedule of every 4 years to ensure the dam's safety and functionality. With its strategic location and purposeful design, Brookville Subdivision Dam plays a crucial role in mitigating flood risks and protecting the surrounding community.
As water resource and climate enthusiasts, it is essential to recognize the importance of structures like Brookville Subdivision Dam in managing water flow and reducing flood risks in vulnerable areas. By staying informed about the dam's specifications, regulatory oversight, and risk assessment, individuals can advocate for proactive measures to ensure the dam's resilience and effectiveness in safeguarding the local environment and community. The commitment to regular inspections, maintenance, and emergency preparedness will be key in preserving the dam's functionality and enhancing overall water resource management practices in the region.

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.
