Summary

Completed in 1964, the dam serves multiple purposes, including flood risk reduction, hydroelectric power generation, recreation, and water supply. With a height of 114 feet and a length of 3200 feet, Eufaula Dam has a significant storage capacity of 3,825,400 acre-feet and a surface area of 143,000 acres.

Despite being classified as having a high hazard potential, a risk assessment conducted by the US Army Corps of Engineers (USACE) in 2017 determined that the risk associated with Eufaula Dam is low. However, in the event of a dam failure, the surrounding areas, including the cities of Whitefield, Webbers Falls, and Moffett in Oklahoma, as well as Ft. Smith and Van Buren in Arkansas, could experience widespread flooding and infrastructure damage. To mitigate this risk, USACE has implemented various measures such as emergency exercises, routine updates to the Emergency Action Plan (EAP), and continuous monitoring and maintenance of the dam.

Overall, Eufaula Dam plays a crucial role in managing water resources and mitigating flood risks in the region. Through proactive risk management measures and ongoing monitoring, USACE is committed to ensuring the safety and integrity of the dam to protect the surrounding communities and infrastructure from potential flooding events.

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.
