Summary
This dam serves multiple purposes, including flood risk reduction, with a primary purpose classified as "Other." The structure stands at a height of 30 feet, with a hydraulic height and structural height of 30 and 33 feet respectively, and a length of 891 feet. It has a storage capacity of 168 acre-feet and a normal storage of 35 acre-feet, covering a surface area of 9 acres and draining an area of 0.8 square miles.
Managed by the local government, the dam is regulated and inspected by the Nebraska Department of Natural Resources. Despite being rated as having a low hazard potential and fair condition, the structure undergoes inspections every 5 years to ensure its integrity and safety. The dam is situated on the TR-N FK Little Nemaha River, within the jurisdiction of the state of Nebraska. Its coordinates are 40.63930358 latitude and -96.04844549 longitude, making it a significant feature in the region's water resource and climate management efforts.
Wilson Creek 4-15 plays a crucial role in the local community's flood risk reduction strategy, contributing to the overall water resource management in the area. As part of the broader network of dams and water infrastructure in Nebraska, this earth dam serves as a key component in the state's efforts to mitigate the impact of extreme weather events and ensure the safety and well-being of its residents. With its design and construction overseen by the Natural Resources Conservation Service, Wilson Creek 4-15 stands as a testament to the collaborative efforts between federal, state, and local agencies in safeguarding water resources and addressing climate challenges in the region.

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.
