Summary
This structure on the South Fork Moreau River stands at 26 feet high, with a length of 575 feet and a maximum storage capacity of 197 acre-feet. The dam, regulated by the South Dakota Department of Agriculture and Natural Resources, has a low hazard potential and a moderate risk assessment rating of 3.
Despite not being rated for its condition, Jim's Creek Dam undergoes regular state inspections, permitting, and enforcement to ensure its safety and functionality. The dam features an uncontrolled spillway with a width of 100 feet and has no outlet gates. With a drainage area of 4 square miles and a maximum discharge capacity of 2080 cubic feet per second, this structure plays a crucial role in managing water resources in the region and mitigating potential flooding risks.
The dam's presence not only protects the surrounding area from flooding but also serves as a significant water management tool for the community. With its strategic location and design, Jim's Creek Dam stands as a testament to the importance of sustainable water resource management in the face of climate change challenges.

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.
