Summary

Built in 1947, this earth dam stands at a height of 14 feet and has a storage capacity of 176 acre-feet. While primarily used for irrigation purposes, Corpening is also regulated by the state and undergoes regular inspections to ensure its structural integrity and safety.

Despite its low hazard potential, Corpening has been assessed to be in poor condition as of August 2021. With a moderate risk rating, measures for risk management and assessment are yet to be fully implemented. The dam's spillway is uncontrolled and measures 40 feet in width, ensuring proper water release during high flow events. Despite its age, Corpening remains a vital resource for the local community, serving as a key component of the irrigation infrastructure in Carbon County, Wyoming.

With its historical significance and ongoing maintenance needs, Corpening stands as a testament to the importance of water resource management and climate resilience in the face of changing environmental conditions. As enthusiasts in this field, understanding the complexities and challenges faced by structures like Corpening is crucial for developing sustainable solutions and safeguarding our water resources for future generations.

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.
