Summary
This earth dam stands at a height of 28 feet and has a structural height of 30.32 feet, with a storage capacity of 68.2 acre-feet. The dam is regulated by the Nebraska Department of Natural Resources, with state permitting, inspection, and enforcement in place to ensure its safety and functionality.
Situated on the TR-N FK LITTLE NEMAHA RIVER, Wilson Creek 12-18 plays a crucial role in managing water resources in the area, with a drainage area of 0.29 square miles and a maximum discharge capacity of 120 cubic feet per second. Despite its low hazard potential, the dam is regularly inspected and maintained to ensure its satisfactory condition and reduce risks associated with potential emergencies. The dam's location in Otoe, Nebraska, underscores its significance in protecting the local community from flooding events and underscores the importance of effective water resource management strategies.
With its solid construction and satisfactory condition assessment, Wilson Creek 12-18 stands as a testament to the collaborative efforts between local government and federal agencies in safeguarding water resources and mitigating flood risks in the region. Designed by the USDA NRCS and overseen by the Nebraska DNR, this dam serves as a vital infrastructure for flood risk reduction while also supporting other purposes. As climate change continues to impact water resources and weather patterns, the role of structures like Wilson Creek 12-18 in enhancing resilience and adaptation to changing conditions becomes increasingly crucial for ensuring the sustainable management of water resources and climate impacts in the area.

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.
