Summary

Completed in 1972, this dam stands at a height of 22 feet and has a storage capacity of 180 acre-feet, with a normal storage level of 110 acre-feet. The dam serves multiple purposes, including flood control and water supply for the surrounding area.

Managed by the Oklahoma Water Resources Board (OWRB), Kerr McGee is state-regulated and regularly inspected for safety and compliance. Despite its low hazard potential, the dam is considered to have a very high risk due to its location and potential impact in case of failure. Emergency action plans are in place, but the dam's condition assessment is currently not rated, highlighting the need for ongoing monitoring and maintenance to ensure its integrity and safety for the community.

With a controlled spillway and outlet gate, Kerr McGee plays a crucial role in managing water flow and mitigating flood risk in the region. As a key infrastructure asset in the Tulsa District, this dam underscores the importance of proactive risk management measures and collaboration between state and federal agencies to safeguard water resources and protect communities from the impacts of extreme weather events and climate change.

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.
