Summary

The dam, made of stone with a soil foundation, stands at a height of 84 feet and spans a length of 1980 feet, providing storage of up to 8000 acre-feet of water from the Greasy Creek.

With a high hazard potential and fair condition assessment, this site is crucial for managing flood risks in the area. The dam features a controlled spillway and a single valve outlet gate, with a maximum discharge capacity of 6350 cubic feet per second. Despite being last inspected in 2011, this structure continues to play a vital role in protecting the local community from potential flooding events.

Overall, SCS-Sallisaw Creek Site-25 serves as a key component in the state's flood risk reduction efforts, reflecting the importance of sustainable water resource management in the face of changing climate patterns. As water resource and climate enthusiasts, it is essential to monitor and maintain such structures to ensure their effectiveness in mitigating the impacts of extreme weather events on local communities and ecosystems.

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.
