Summary
Built in 1964 by the USDA NRCS, this earth dam stands at 33 feet high and stretches 542 feet in length, providing a storage capacity of 36 acre-feet. With a high hazard potential but a satisfactory condition assessment as of March 2020, Wilson Creek 2-N plays a vital role in protecting the surrounding area from flooding events.
Managed by the local government and regulated by the NE Department of Natural Resources, Wilson Creek 2-N is subject to state permitting, inspection, and enforcement. Its primary purpose is flood risk reduction, with a maximum discharge capacity of 450 cubic feet per second. Despite its age, this structure has been well-maintained and meets the necessary safety guidelines, ensuring its effectiveness in mitigating flood risks in the region.
With a hydraulic height of 31 feet and a surface area of 1 acre, Wilson Creek 2-N is a key component of the water resource infrastructure in the area. Its location, design, and operational history make it a critical asset for climate resilience efforts in Otoe, Nebraska, demonstrating the importance of proactive flood risk management in the face of changing environmental conditions.

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.
