Summary
Built in 1965 by the USDA NRCS, this earth dam stands at a height of 46 feet and serves primarily for flood risk reduction. With a storage capacity of 3486 acre-feet, it plays a crucial role in managing water levels and protecting the surrounding area from potential flooding events. The dam's significant hazard potential underscores the importance of regular inspections and maintenance to ensure its structural integrity and continued functionality.
Managed by the local government and regulated by the Arkansas Natural Resources Commission, Poteau River Wid Site 02 has been identified as having a moderate risk level. Despite not being rated for its current condition, it remains a critical infrastructure for the community's safety and water resource management. The dam's spillway, outlet gates, and uncontrolled nature highlight the need for effective risk assessment and management measures to mitigate potential hazards and safeguard the surrounding environment.
As part of the flood risk reduction system in Scott County, Arkansas, Poteau River Wid Site 02 plays a vital role in protecting the local community from the impacts of extreme weather events and ensuring water resource sustainability. With its historical significance and ongoing regulatory oversight, this dam stands as a testament to the collaborative efforts between federal agencies, designers, and local stakeholders in managing and preserving vital water resources for future generations.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
