Summary
This earth dam stands at a height of 30 feet and spans a length of 1480 feet, with a storage capacity of 1200 acre-feet. Completed in 1980, it serves the primary purpose of mitigating flood risks in the area, with a low hazard potential and fair condition assessment as of the last inspection in 2016.
Situated along the TR-N FK Little Nemaha River, Wilson Creek 12-T is regulated by the NE DNR and falls under the jurisdiction of the state of Nebraska. With a drainage area of 3.3 square miles and a maximum discharge capacity of 659 cubic feet per second, this structure plays a vital role in managing water resources in the region. Despite its age, Wilson Creek 12-T continues to operate effectively, meeting state permitting, inspection, and enforcement requirements to ensure optimal functionality.
As a key component of flood control infrastructure in Nebraska, Wilson Creek 12-T exemplifies the importance of proactive water resource management in the face of climate variability. With its strategic location, sturdy construction, and ongoing regulatory oversight, this earth dam stands as a testament to the collaborative efforts of local government, state agencies, and the USDA NRCS in safeguarding communities against the impacts of extreme weather events.

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.
