Summary
Completed in 1980, this earth dam stands at a height of 34 feet and has a structural height of 35 feet, providing a vital flood control measure for the region. With a storage capacity of 1308 acre-feet and a normal storage of 31 acre-feet, it covers a surface area of 58 acres and drains a 4.1 square mile watershed.
Managed by the local government and regulated by the NE DNR, Wilson Creek 10-E has a low hazard potential and is deemed to be in satisfactory condition as per the last assessment in May 2016. With a maximum discharge capacity of 567 cubic feet per second, it plays a crucial role in safeguarding the surrounding communities from potential flood events. Despite no associated structures, the dam is subject to regular inspections every five years, ensuring its operational readiness and effectiveness in flood mitigation measures.
Overall, Wilson Creek 10-E serves as a testament to effective water resource management and climate resilience efforts in Nebraska. With its strategic location and design, this dam stands as a reliable barrier against flood risks, highlighting the collaborative efforts between local governments and federal agencies in safeguarding communities and natural resources from the impacts of extreme weather events. Its functionality and maintenance reflect a commitment to sustainable water resource management practices for the benefit of present and 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.
