Summary
Completed in 1968, this dam stands at a height of 36 feet and stretches 890 feet in length, offering a storage capacity of 556 acre-feet to help mitigate potential flooding in the area. With a significant hazard potential and a fair condition assessment as of May 2019, Wilson Creek 8-B plays a crucial role in safeguarding the surrounding community from the impacts of extreme weather events.
Managed by the local government and regulated by the NE DNR, Wilson Creek 8-B is subject to state permitting, inspection, and enforcement to ensure its structural integrity and operational effectiveness. Situated within the Kansas City District, this earth dam is constructed with stone core types on a soil foundation and has a hydraulic height of 29 feet. Its normal storage capacity is 101 acre-feet, with a drainage area of 1.5 square miles and a maximum discharge capacity of 1831 cubic feet per second, helping to control water flow and minimize flood risks in the region.
As water resource and climate enthusiasts continue to monitor and assess the resilience of infrastructure like Wilson Creek 8-B, its role in flood risk reduction and water management remains of utmost importance. With a focus on safety and preparedness, ongoing inspections and maintenance efforts are essential to ensure the continued effectiveness of this critical earth dam in protecting the community and surrounding areas from the impacts of natural disasters and 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.
