Summary
Completed in 1968, this earth dam stands at a height of 29 feet with a hydraulic height matching that figure. Its primary purpose is flood risk reduction, boasting a normal storage capacity of 24 acre-feet across a surface area of 5 acres. The dam's drainage area is 0.6 square miles, with a maximum discharge capacity of 596 cubic feet per second.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Wilson Creek 1-24 has a low hazard potential but is currently assessed to be in poor condition. Despite its critical role in flood protection, the dam's structural integrity may need attention to ensure its continued effectiveness. With a five-year inspection frequency, the last assessment took place in June 2020. As such, further maintenance and potential improvements could be necessary to enhance its overall performance and resilience in the face of changing climate conditions.
Situated along the TR-N Fork Little Nemaha River, Wilson Creek 1-24 is overseen by the Kansas City District of the US Army Corps of Engineers. The dam's construction utilized stone core types on a soil foundation, measuring 500 feet in length with a total height of 32 feet. While the dam is owned by the local government, it receives no federal funding or oversight. As water resource and climate enthusiasts, understanding the significance and condition of structures like Wilson Creek 1-24 is crucial for managing flood risks and safeguarding communities and ecosystems in the region.

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.
