Summary
Completed in 1973 by the USDA NRCS, this dam serves the primary purpose of water resource management on Spring Creek, with a storage capacity of 2005 acre-feet. The dam is regulated by the South Dakota Department of Agriculture and Natural Resources, ensuring regular inspections and enforcement of safety measures.
The dam has a significant hazard potential and has not been rated for its condition assessment. Despite being constructed almost 50 years ago, the last inspection was conducted in 1980. Dusty Johnson (R) represents the area in Congress, and the St. Paul District of the US Army Corps of Engineers oversees the dam's operation. With a drainage area of 17 square miles and a maximum discharge of 15,302 cubic feet per second, Spring-Bull Creek Dt Dam Sb-1 plays a crucial role in flood control and water supply management in the region.
As water resource and climate enthusiasts, understanding the details of Spring-Bull Creek Dt Dam Sb-1 provides insight into the infrastructure that supports water management in South Dakota. With its historical significance and importance in regulating water flow on Spring Creek, this Earth dam stands as a testament to the ongoing efforts to safeguard water resources and mitigate the impact of extreme weather events in the area.

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.
