Summary
Built in 1979 by the USDA NRCS, this earth dam stands at a height of 54.8 feet and serves as a crucial resource for managing water levels in the area. With a storage capacity of 2195.2 acre-feet and a normal storage level of 454.8 acre-feet, the dam plays a key role in protecting the surrounding community from potential flooding events.
Managed by the Nebraska Department of Natural Resources, North Oak Creek 4-A is regularly inspected and maintained to ensure its structural integrity and functionality. Despite its low hazard potential, the dam is classified as satisfactory in condition assessment, providing reassurance to local residents and stakeholders. Additionally, the presence of a spillway and emergency action plan readiness further enhances the safety and risk management measures associated with this essential infrastructure project.
Under the jurisdiction and regulation of the NE DNR, North Oak Creek 4-A not only serves as a flood risk reduction measure but also contributes to the overall water resource management of the region. With its strategic location and design by the Natural Resources Conservation Service, this dam exemplifies the importance of proactive and coordinated efforts in safeguarding communities against the impacts of extreme weather events and climate variability.

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.
