Summary
Built in 1961, this earth dam stands at a height of 16.9 feet and spans 435 feet in length, with a storage capacity of 246 acre-feet. Managed by the Nebraska Department of Natural Resources, the dam is regularly inspected and maintained to ensure its structural integrity and effectiveness in managing water flow.
With a significant hazard potential, Wilsonville Dam is designed to protect the surrounding area from potential flooding events, with a normal storage capacity of 156.5 acre-feet. While the dam's condition assessment is currently not rated, it undergoes inspections every three years to ensure its continued safety and functionality. The dam's location in the Omaha District, under the jurisdiction of the state regulatory agency, highlights the collaborative efforts in place to monitor and manage water resources in the region.
Despite its private ownership, Wilsonville Dam serves a critical purpose in mitigating flood risks and safeguarding the community against potential water-related hazards. As a key infrastructure within the local landscape, the dam's presence underscores the importance of proactive water resource management and the need for ongoing maintenance to uphold its vital role in protecting the surrounding area from the impacts of extreme weather events and water flow.

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.
