Summary

Owned by the local government and regulated by the Nebraska Department of Natural Resources, this earth dam stands at a height of 46 feet and stretches out to 1563 feet in length. Completed in 1971, it serves the primary purpose of flood risk reduction, with a normal storage capacity of 253 acre-feet and a maximum storage of 5375 acre-feet.

Designed by the USDA NRCS, Mud Creek 2-A has a high hazard potential and is classified as being in fair condition as of the latest inspection in November 2020. With a drainage area of 20.6 square miles and the ability to discharge up to 8432 cubic feet per second, this structure plays a crucial role in managing water resources in the region. Although it has not been modified in recent years, it is regularly inspected and maintained to ensure its effectiveness in protecting the surrounding area from potential flooding events.

Overall, Mud Creek 2-A stands as a testament to the collaborative efforts between federal, state, and local agencies in safeguarding communities against the impacts of extreme weather events. As climate change continues to pose challenges to water resource management, structures like Mud Creek 2-A play a crucial role in enhancing resilience and mitigating flood risks in the face of a changing climate.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
