Summary

Standing at 161 feet in height and with a hydraulic height of 154 feet, this structure serves a critical role in managing water resources in the region. With a storage capacity of 290,550 acre-feet and a surface area of 13,524 acres, Mcgee Creek plays a vital role in flood control, irrigation, and water supply for the surrounding area.

The dam has a controlled spillway with a width of 722 feet, emphasizing its ability to manage high water levels effectively. Despite its high hazard potential, Mcgee Creek has not undergone a recent condition assessment, but its risk assessment indicates a very high level of risk. With a drainage area of 178 square miles, this dam plays a crucial role in protecting downstream areas from potential flooding events. As a key component of the Bureau of Reclamation's operations, Mcgee Creek represents a critical piece of infrastructure for water resource management and climate resilience in Oklahoma.

Overall, Mcgee Creek stands as a testament to the importance of infrastructure in managing water resources and mitigating the impacts of climate change. Its construction and operation by the Bureau of Reclamation highlight the dedication to ensuring the safety and reliability of water supply systems in the region. With its significant storage capacity and high hazard potential, Mcgee Creek plays a pivotal role in safeguarding communities and ecosystems from the risks associated with extreme weather events and changing climate patterns.

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.
