Summary

Completed in 1969, this earth dam stands at 53 feet in height and spans 2395 feet in length, providing crucial flood protection to the surrounding area. With a storage capacity of 7972 acre-feet and a drainage area of 12.1 square miles, this dam plays a vital role in managing water resources and protecting the community from potential flood events.

Managed by the local government and regulated by the ANRC, Poteau River Wid Site 11 is subject to regular inspections and enforcement to ensure its structural integrity and safety. Despite its low hazard potential, the dam is classified as having a moderate risk level, indicating the importance of ongoing risk management measures. With a spillway type of "Uncontrolled" and uncontrolled outlet gates, the dam operates efficiently to control water flow and prevent overflow during high-discharge events, further enhancing its flood risk reduction capabilities.

Overall, Poteau River Wid Site 11 serves as a critical piece of infrastructure for flood risk reduction in the region, providing essential protection for the community against potential water-related disasters. With its strategic design and operational features, this dam exemplifies the importance of sustainable water resource management and climate resilience in safeguarding communities against the impacts of extreme weather 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.
