Summary
Completed in 1952, this earth dam has a storage capacity of 40 acre-feet and a maximum discharge of 312 cubic feet per second. Despite being state regulated and inspected, its condition assessment is currently not rated. The dam is situated on a tributary of the Missouri River and falls under the jurisdiction of the South Dakota Department of Environment and Natural Resources.
This structure plays a crucial role in water resource management in the region, providing flood control and water storage for local communities. With its strategic location and functional design, Joe Svoboda #2 contributes to the overall water infrastructure of the area. As climate change continues to impact water resources, the importance of maintaining and monitoring dams like Joe Svoboda #2 becomes increasingly vital to ensure their safety and effectiveness in the face of evolving environmental conditions.
As a key component of the St. Paul District, Joe Svoboda #2 represents a critical piece of the larger water management puzzle in South Dakota. With its historical significance and ongoing regulatory oversight, this dam serves as a reminder of the intricate balance between human infrastructure and natural ecosystems. For water resource and climate enthusiasts, understanding the role of structures like Joe Svoboda #2 is essential in promoting sustainable water use and resilience in the face of a changing climate.

Dam Data Reference
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.
