Summary

This earth dam, completed in 1967, stands at a height of 48 feet and serves the primary purpose of flood risk reduction along the TR-Sallisaw Creek. With a storage capacity of 560 acre-feet and a surface area of 6 acres, this dam plays a crucial role in protecting the surrounding area from potential flooding events.

Despite being categorized as having a low hazard potential, the risk assessment for SCS-Sallisaw Creek Site-21 indicates a very high risk level. While the condition assessment is currently not rated, the dam has not been inspected since 1980. It is imperative that regular inspections are conducted to ensure the structural integrity of the dam and to mitigate any potential risks associated with its operation. Additionally, with the emergency action plan status unclear, it is essential that protocols are in place to respond effectively in case of any unforeseen emergencies related to the dam.

Overall, SCS-Sallisaw Creek Site-21 is a vital infrastructure for flood risk reduction in Adair County, Oklahoma. With its strategic location and design, this dam serves as a key component in managing water resources and climate challenges in the region. However, ongoing maintenance, inspections, and emergency preparedness are crucial to ensure the safety and effectiveness of this important water management structure.

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.
