Summary
Hunt is a privately owned earth dam located in Ziebach, South Dakota, along the TR-CHEYENNE river. Built in 1969 by the Natural Resources Conservation Service, this dam stands at a height of 29 feet and has a length of 500 feet. With a storage capacity of 244 acre-feet, E. Hunt serves as a crucial water resource for the region, providing a normal storage of 139 acre-feet and a maximum discharge of 2100 cubic feet per second.
Despite its low hazard potential, E. Hunt is regulated by the South Dakota Department of Environment and Natural Resources, with state permitting, inspection, and enforcement in place. The dam has not been rated for condition assessment, and emergency action plans and inundation maps are yet to be prepared. While there have been no modifications or inspections reported recently, E. Hunt remains a significant piece of infrastructure in the region, contributing to water resource management and climate resilience efforts.
Overall, E. Hunt plays a vital role in water storage and management in South Dakota, serving as a key structure in the St. Paul District. With its low hazard potential and state regulation, this earth dam stands as a testament to effective water resource governance. As climate change continues to impact water availability and quality, E. Hunt's role in ensuring sustainable water supply for the region becomes increasingly important, highlighting the need for ongoing monitoring and maintenance of this critical infrastructure.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
