Summary

Completed in 1956, this earth dam stands at a height of 13 feet and has a storage capacity of 52 acre-feet. The dam is situated on the TR Cut Meat Creek Offstream, and it is regulated by the South Dakota Department of Environment and Natural Resources.

Despite its low hazard potential, Wm Kary #2 has not been rated for its condition assessment. The dam has not undergone recent inspections, and there is no Emergency Action Plan (EAP) in place. While the dam meets state permitting, inspection, and enforcement requirements, there are no specific risk management measures or guidelines outlined for potential emergencies or failures. The dam is not associated with any federal agencies, and its oversight and maintenance fall solely on the private owner.

For water resource and climate enthusiasts, Wm Kary #2 serves as a reminder of the importance of regular inspections, condition assessments, and emergency preparedness for dams, particularly those in private ownership. As climate change continues to impact water resources and infrastructure, it is crucial for dam owners, regulators, and stakeholders to work together to ensure the safety and resilience of these structures in the face of evolving environmental challenges. The data on Wm Kary #2 highlights the need for proactive risk management and maintenance practices to safeguard both the dam and the surrounding community from potential hazards.

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.
