Summary

Completed in 1980, this earth dam serves primarily for recreational purposes, offering a serene escape for visitors to enjoy the surrounding beauty. With a height of 21 feet and a length of 400 feet, the dam provides a maximum storage capacity of 50 acre-feet, with a normal storage level of 37 acre-feet.

Managed by private ownership and regulated by the New York State Department of Environmental Conservation, Leroy Denbesten Pond Dam poses a low hazard potential with a moderate risk assessment rating. Despite being last inspected in 1994, its structural integrity and condition remain unassessed. The dam's spillway type is uncontrolled, with a width of 70 feet, allowing for a maximum discharge of 86 cubic feet per second. The dam's location along the TR-MULTZES KILL river/stream adds to its charm and importance within the surrounding ecosystem.

As water resource and climate enthusiasts, the Leroy Denbesten Pond Dam presents an intriguing case study in the management and maintenance of recreational water structures. With its untapped potential for further inspection and risk assessment, it serves as a reminder of the delicate balance between human recreation and environmental stewardship. As we continue to monitor and preserve our water resources, Leroy Denbesten Pond Dam stands as a testament to the importance of sustainable practices in preserving our natural landscapes for future generations.

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.
