Summary
With a height of 25 feet and a length of 465 feet, the dam serves the primary purpose of water storage for irrigation and flood control along the TR-Grand River. Managed by the Natural Resources Conservation Service, the dam has a storage capacity of 161 acre-feet, with a normal storage level of 135 acre-feet.
Despite being classified as a low hazard potential structure, Praire Dog Creek Dam is regulated by the South Dakota Department of Environment and Natural Resources, ensuring that it meets state inspection, enforcement, and permitting requirements. While the dam's condition assessment is currently listed as "Not Rated," it is important to note that emergency action plans have not been updated, and there is no information available on risk assessment or management measures. With Dusty Johnson (R) as the congressional representative for the area, stakeholders and enthusiasts should stay informed about the dam's safety and management practices to ensure the protection of water resources and the surrounding ecosystem in the region.

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.
