Summary
Built in 1976 by the Natural Resources Conservation Service, this earth dam stands at a height of 21 feet and has a storage capacity of 234 acre-feet. The dam serves as a barrier on Blind Creek, with a drainage area of 6 square miles, helping to control water flow and prevent flooding in the area.
With a low hazard potential and a condition assessment of "Not Rated," Jensen Dam is maintained to meet state regulatory standards by the Department of Environment and Natural Resources. Despite its modest size, the dam plays a significant role in water management in the region, with a maximum discharge capacity of 2900 cubic feet per second. While the dam's primary purpose is not specified, its construction and operation are overseen by state agencies to ensure its safety and functionality for the community.
Jensen Dam stands as a testament to the importance of water resource management in South Dakota, providing crucial support in controlling water flow and mitigating flood risks in the area. As climate change continues to impact weather patterns and water availability, structures like Jensen Dam become even more vital in ensuring the resilience of local communities and ecosystems. With its modest size and low hazard potential, Jensen Dam serves as a reliable and effective tool in safeguarding the region's water resources for future generations.

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.
