Summary

Built in 1973 by the USDA NRCS, this dam serves as a crucial flood risk reduction measure for the area. Standing at a height of 26 feet with a structural height of 32 feet, Cub Creek 13-D has a storage capacity of 701 acre-feet and covers a drainage area of 1.6 square miles.

Despite its importance in mitigating flood risks, Cub Creek 13-D is currently assessed as being in poor condition, with a low hazard potential. The last inspection in May 2019 highlighted the need for improvements to ensure the dam's structural integrity and effectiveness in managing water flow. With a history of modifications and maintenance, this dam continues to play a vital role in protecting the surrounding community from potential flooding events, emphasizing the importance of ongoing monitoring and maintenance efforts to ensure its continued functionality.

As water resource and climate enthusiasts, understanding the critical role of infrastructure like Cub Creek 13-D in managing water flow and reducing flood risks is essential. By staying informed about the condition and maintenance needs of dams like these, we can contribute to the preservation of these vital resources and the protection of communities that rely on them for flood prevention and water management.

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.
