Summary

Completed in 2011, this earth dam stands at a height of 34 feet with a storage capacity of 50.5 acre-feet. Situated along Horseshoe Creek, this structure plays a crucial role in maintaining water levels for agricultural activities in the area.

Despite its low hazard potential, Key Bar Water Hole #1 has been assessed to be in fair condition as of May 2021. Regular inspections are conducted every 5 years to ensure the safety and integrity of the dam. With the state of Wyoming being the primary source agency overseeing its regulation and enforcement, this water hole serves as a vital resource for the local community and contributes to the overall water management efforts in the region.

Supported by the Omaha District and Congressional Representative Liz Cheney (R), this water hole exemplifies the collaboration between private owners and state agencies in managing water resources effectively. With its strategic location and significant storage capacity, Key Bar Water Hole #1 stands as a testament to the importance of sustainable water management practices in the face of changing climate 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.
