Summary

This earth dam has a height of 15 feet and a storage capacity of 200 acre-feet. The dam's primary purpose is listed as "other," with an uncontrolled spillway type and a width of 10 feet.

Managed by the New York State Department of Environmental Conservation (NYS DEC), the Hampshire Country Club Dam has not been rated for its condition assessment and does not currently have an emergency action plan in place. The last inspection was conducted in July 2020, showing compliance with state permitting, inspection, and enforcement requirements. With a risk assessment score of 3 out of 5, the dam's risk management measures and inundation maps have yet to be prepared.

For water resource and climate enthusiasts, the Hampshire Country Club Dam offers a fascinating case study in dam management and regulation. With its picturesque location and unique design features, this dam serves as a vital piece of infrastructure in the region. As stakeholders continue to monitor and assess the dam's condition, there is a growing need for comprehensive risk management strategies to ensure the safety and integrity of this important water resource asset.

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.
