Summary

Constructed in 1968 by the US Army Corps of Engineers, this dam serves multiple purposes including flood risk reduction, hydroelectric power generation, recreation, and water supply. With a structural height of 225 feet and a length of 4026 feet, the dam has a storage capacity of 1,598,950 acre-feet and a maximum discharge of 443,000 cubic feet per second.

The dam's low hazard potential and very high risk assessment highlight the importance of effective risk management measures in place. The USACE actively monitors and maintains the dam to manage flood risks, engage with emergency managers, and develop emergency action plans. By prioritizing activities to mitigate risks and collaborating with local authorities, the USACE ensures the safety and structural integrity of Broken Bow Dam. Despite its limitations in storing water, the dam plays a critical role in flood control and water management for the surrounding area.

Overall, Broken Bow Dam stands as a vital piece of infrastructure in Oklahoma, safeguarding against floods and providing essential services to the community. As climate change impacts water resources and weather patterns, the ongoing management and maintenance of this dam will be essential to adapt to changing conditions and ensure the safety of downstream populations.

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.
