Summary
Owned by the local government and designed by USDA NRCS, this earth dam stands at a height of 52 feet with a hydraulic height of 49 feet. Completed in 1976, the dam has a storage capacity of 450 acre-feet and covers a surface area of 22 acres, serving a drainage area of 1.6 square miles. With a low hazard potential and satisfactory condition assessment, North Oak Creek 6-B plays a vital role in protecting the surrounding area from potential flooding events.
Managed by the Nebraska Department of Natural Resources, this dam undergoes regular inspections every 5 years to ensure its structural integrity and effectiveness. The dam has a spillway type and width unspecified, and no associated locks. Despite its age, North Oak Creek 6-B continues to meet regulatory standards and is deemed to be in satisfactory condition. With the support of the local government and federal agencies, this dam remains a crucial asset in the region's water resource management and climate resilience efforts.
As part of the Kansas City District, North Oak Creek 6-B contributes to the overall flood risk reduction strategy in the area. With a primary purpose of flood risk reduction, this dam has successfully mitigated potential hazards for the local community. Supported by the Natural Resources Conservation Service, North Oak Creek 6-B stands as a testament to effective water resource management and climate adaptation practices in Nebraska.

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.
