Summary
Completed in 1980 by the USDA NRCS, this earth dam stands at a height of 43 feet and stretches 720 feet in length, providing essential protection to the surrounding area. With a storage capacity of 637 acre-feet and a drainage area of 2.2 square miles, North Oak Creek 4-C plays a crucial role in mitigating flood hazards and safeguarding the local community against potential water-related disasters.
Managed by the Nebraska Department of Natural Resources, this dam has been deemed to have a low hazard potential and is currently in satisfactory condition as of the last assessment in September 2019. With a primary purpose of flood risk reduction, North Oak Creek 4-C serves as a crucial component in the region's water resource management strategy. Additionally, the structure is regularly inspected every five years to ensure its continued effectiveness and safety, demonstrating a commitment to the ongoing maintenance and oversight of this essential infrastructure.
Situated under the jurisdiction of the NE DNR, North Oak Creek 4-C stands as a testament to effective collaboration between local government agencies and the USDA NRCS in addressing water resource and climate challenges in the region. With a focus on flood risk reduction and a history of successful performance since its completion, this earth dam serves as a beacon of resilience in the face of potential natural disasters, embodying the importance of proactive water resource management in safeguarding communities against the impacts of a changing climate.

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.
