Summary

It spans 275 feet in length and stands at a height of 25 feet, providing a storage capacity of 43.3 acre-feet. Situated on TR-CAZANOVIA CREEK, the dam's spillway is uncontrolled with a width of 9 feet, allowing for a maximum discharge of 83.9 cubic feet per second.

Managed by the NYS DEC, Denz Pond Dam is regulated, permitted, inspected, and enforced by the state agency, ensuring its safety and compliance with regulations. Despite being classified as a low hazard potential structure and not having a current condition assessment rating, the dam presents a moderate risk (3) based on the available data. With its location in Erie County, New York, and its role in water resource management and recreational activities, Denz Pond Dam serves as a vital infrastructure for the local community and wildlife.

Water resource and climate enthusiasts can appreciate Denz Pond Dam for its contribution to fire protection, stock, and ecological preservation in the region. The dam's storage capacity, spillway design, and regulatory oversight by the NYS DEC highlight its importance in water management and safety. As a relatively new structure completed in the early 2000s, Denz Pond Dam represents modern engineering practices in building resilient infrastructure for sustainable water resource utilization and habitat conservation along TR-CAZANOVIA CREEK.

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.
