Summary
Completed in 1949, this dam on the TR-Grand River has a storage capacity of 71 acre-feet, with a maximum discharge of 1,664 cubic feet per second. While its hazard potential is rated as low and its condition is not yet assessed, Joe Wiesinger is regulated, permitted, inspected, and enforced by the South Dakota Department of Environment and Natural Resources.
Located within the St. Paul District of the US Army Corps of Engineers, Joe Wiesinger serves a vital role in water resource management and flood control efforts in the region. Despite not having a designated primary purpose, the dam plays a crucial role in mitigating potential risks associated with the Grand River, ensuring the safety and well-being of nearby communities. With its historical significance and ongoing regulatory oversight, Joe Wiesinger stands as a testament to the importance of sustainable water infrastructure in the face of changing climate conditions.
As a key structure in the local water management system, Joe Wiesinger represents a blend of historical engineering excellence and modern regulatory practices. While its current condition is not rated, the dam continues to be a focal point for environmental stewardship and climate resilience efforts in South Dakota. With its low hazard potential and regulatory compliance, Joe Wiesinger exemplifies the importance of proactive dam management and maintenance in safeguarding water resources for future generations.

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.
