Summary

Completed in 1973, this earth dam stands at a height of 32 feet and has a storage capacity of 729 acre-feet, serving as a crucial tool for flood risk reduction in the region. With a drainage area of 1.9 square miles and a maximum discharge capacity of 656 cubic feet per second, Cub Creek 17-B plays a significant role in managing water resources in the surrounding area.

Managed by the local government and regulated by the Nebraska Department of Natural Resources, Cub Creek 17-B has been inspected periodically to ensure its structural integrity and functionality. The dam has been assessed as satisfactory, with a significant hazard potential due to its location and purpose. Despite its age, Cub Creek 17-B continues to play a critical role in protecting the community from potential flooding events, showcasing the importance of sustainable water resource management and climate resilience in the face of changing environmental conditions.

As a part of the flood risk reduction infrastructure in Nebraska, Cub Creek 17-B serves as a testament to the collaborative efforts between federal and local agencies in safeguarding communities against natural disasters. With its stone core and soil foundation, this dam embodies the principles of sound engineering and environmental stewardship in water resource management. As climate change continues to pose challenges to water availability and quality, structures like Cub Creek 17-B are essential for adapting to the evolving climate conditions and ensuring the long-term sustainability of water resources in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
