Summary
Completed in 1967, this earth dam stands at 33 feet tall and stretches 950 feet in length, serving primarily for flood risk reduction along the TR-N FK LITTLE NEMAHA RIVER. With a storage capacity of 799 acre-feet and a drainage area of 2.2 square miles, Wilson Creek 2-S plays a crucial role in managing water flow and mitigating potential flood hazards in the region.
Despite its age, Wilson Creek 2-S has been assessed as being in satisfactory condition, with a low hazard potential. The dam's last inspection was conducted in June 2016, with a recommended inspection frequency of 5 years. The dam has not experienced any modifications in recent years, and while an Emergency Action Plan (EAP) is not currently in place, the dam's risk management measures and adherence to guidelines are yet to be fully documented. With its vital role in flood risk reduction and water resource management, Wilson Creek 2-S stands as a significant infrastructure asset in the region, ensuring the safety and wellbeing of nearby communities in the face of potential climate-related challenges.

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.
