Summary

Completed in 1971, this earth dam stands at a height of 27 feet, with a hydraulic height of 26 feet and a structural height of 32 feet. It spans 1140 feet in length and has a storage capacity of 1421 acre-feet, serving the purpose of flood risk reduction for the local community.

Managed by the Nebraska Department of Natural Resources, Cub Creek 10-A is regularly inspected and maintained to ensure its fair condition and low hazard potential. Its primary function is to protect the surrounding area from potential flooding, with a drainage area of 3.3 square miles and a maximum discharge capacity of 680 cubic feet per second. The dam's location on TR-Cub Creek highlights its strategic importance in safeguarding the city of Beatrice and its residents from water-related emergencies.

With a surface area of 51 acres and a normal storage capacity of 226 acre-feet, Cub Creek 10-A plays a crucial role in water resource management in the region. As a key part of the flood control infrastructure, this dam demonstrates the collaborative efforts between local government agencies and the USDA NRCS to safeguard communities and enhance climate resilience in Nebraska.

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.
