Summary
Built in 1973 by the USDA NRCS, this earth dam stands at a height of 75 feet and has a maximum storage capacity of 5003 acre-feet. With a normal storage capacity of 24 acre-feet, this dam plays a crucial role in mitigating flood risks in the area, with a low hazard potential and a satisfactory condition assessment as of May 2020.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Upper Medicine Creek 370 serves as a key infrastructure for protecting the surrounding areas from potential flooding events. Situated on Frazier Creek, the dam spans 810 feet in length and covers a drainage area of 26.5 square miles. With a maximum discharge capacity of 20400 cubic feet per second, this structure plays a crucial role in safeguarding the community and enhancing water resource management in the region.
With its strategic location and effective design, Upper Medicine Creek 370 exemplifies the importance of sustainable water resource management and climate resilience in the face of increasing climate variability. As a vital flood risk reduction structure in the area, this earth dam stands as a testament to the collaborative efforts between local government agencies and the USDA NRCS in safeguarding communities and enhancing water security in Nebraska.

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.
