Summary

Completed in 1980, this earth dam with a stone core stands at a height of 18.3 feet and spans 530 feet in length. With a storage capacity of 50.4 acre-feet, this dam plays a vital role in managing water resources in the area.

Despite its essential function, Frontier County Road Dam 2 is currently assessed as being in poor condition, with a low hazard potential. The dam is under the jurisdiction of the Nebraska Department of Natural Resources, which oversees its regulation, permitting, inspection, and enforcement. The last inspection in September 2018 highlighted the need for maintenance and improvements to ensure the dam's continued effectiveness in mitigating flood risks and protecting the surrounding community.

As water resource and climate enthusiasts, it is essential to monitor the condition and maintenance of structures like Frontier County Road Dam 2 to safeguard against potential hazards and ensure their long-term sustainability. By staying informed about the state of infrastructure like this dam, we can contribute to the sustainable management of water resources and protection against the impacts of climate change in our communities.

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.
