Summary
Standing at a height of 32 feet and a length of 1150 feet, this dam has a storage capacity of 418 acre-feet and a spillway width of 1 foot. Despite its age, the dam has not been rated for its condition, posing a high hazard potential. The dam is equipped with a single valve outlet gate for water release.
With a maximum discharge capacity of 990 cubic feet per second, SCS-Sallisaw Creek Site-02 presents a serious flood risk reduction structure in the region. However, with its high hazard potential and lack of recent condition assessment, there is a need for regular inspections and potential risk management measures to ensure the safety and effectiveness of this critical infrastructure. The dam falls under the jurisdiction of the OWRB and is subject to state permitting, inspection, and enforcement.
Overall, SCS-Sallisaw Creek Site-02 serves as a vital flood control structure in the area, with a very high risk assessment rating. As climate change continues to impact water resources and weather patterns, the maintenance and monitoring of this dam will be crucial to protect downstream communities and infrastructure from potential flooding events. Collaboration between state and federal agencies will be essential in ensuring the ongoing safety and functionality of this important water resource management asset.

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.
