Summary

Built in 1906, this earth dam stands at a height of 42 feet and has a length of 1100 feet, providing a storage capacity of 2850 acre-feet. With a surface area of 94 acres and a drainage area of 0.15 square miles, the dam plays a vital role in regulating water flow and ensuring a stable water supply for the region.

Managed by the local government and regulated by the NYS DEC, the Jerome Park Reservoir Dam has a high hazard potential but is currently assessed as satisfactory in condition. The dam features an uncontrolled spillway with a width of 16 feet and a maximum discharge capacity of 200 cubic feet per second. Despite its age, the dam undergoes regular inspections, with the last assessment conducted in November 2019, ensuring its safety and reliability for the surrounding community.

With a moderate risk assessment rating, the Jerome Park Reservoir Dam continues to serve as a vital infrastructure for water resource management in the area. Its historical significance and ongoing maintenance highlight the importance of preserving and safeguarding this critical piece of infrastructure for future generations. Climate and water resource enthusiasts will find the Jerome Park Reservoir Dam to be a captivating example of engineering ingenuity and environmental stewardship in action.

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.
