Summary
This Earth-type dam has a storage capacity of 58 acre-feet and a maximum discharge of 1200 cubic feet per second. Despite being privately owned, the dam is regulated and inspected by the South Dakota Department of Environment and Natural Resources.
Although the dam's hazard potential is considered low, its condition assessment is currently not rated. The dam does not have an Emergency Action Plan (EAP) prepared, and there is no information available on risk assessment or management measures. With no associated structures and limited data on its safety protocols, water resource and climate enthusiasts may be interested in further studying the potential environmental impact and risk factors associated with Joes Spreader Dam.
Given its location and characteristics, Joes Spreader Dam presents an intriguing case study for those interested in water resource management and climate resilience. The dam's history, design, and regulatory oversight offer valuable insights into the complexities of balancing water infrastructure development with environmental protection. As discussions on sustainable water management continue, understanding the intricacies of dams like Joes Spreader Dam can provide valuable lessons for ensuring the long-term safety and resilience of water resources in the face of changing climate conditions.

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.
