Summary

This earth dam has a height of 33 feet and a hydraulic height of 29 feet, with a storage capacity of 362 acre-feet. Its primary purpose is flood risk reduction, serving to protect the surrounding area from potential inundation during periods of high discharge.

Despite its important role in mitigating flood risks, Clatonia Creek 2-A is currently assessed as being in poor condition, with a low hazard potential. The dam is regulated by the Nebraska Department of Natural Resources, which conducts regular inspections to ensure its structural integrity. The last inspection took place in June 2020, with a scheduled inspection frequency of every 5 years.

This structure, managed by the local government, serves as a crucial asset in safeguarding the community against flooding events. As water resource and climate enthusiasts, it is essential to monitor and support the maintenance and improvement of infrastructure like Clatonia Creek 2-A to ensure its continued effectiveness in protecting lives and property in the face of changing environmental conditions.

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.
