Summary

Managed by the USDA NRCS, this earth dam stands at a height of 62 feet and was completed in 1964 for the primary purpose of water supply. With a storage capacity of 4800 acre-feet and a surface area of 358 acres, this dam on Sallisaw Creek plays a crucial role in meeting water supply needs in the region.

The dam's spillway is controlled with a width of 4 feet, and it has a hazard potential classified as high, with a fair condition assessment. Despite its age, the dam has a very high risk rating (1) and is regulated by the OWRB. While the last inspection was conducted in December 2011, the dam's emergency action plan status and risk management measures are currently unknown. With a maximum discharge capacity of 2900 cfs, this site presents both challenges and opportunities for water resource and climate enthusiasts interested in dam safety and water supply management.

Although the dam shows signs of age and has a high hazard potential, it remains a critical water supply infrastructure in Sallisaw, Oklahoma. With its controlled spillway and valve outlet gates, the dam continues to serve its primary purpose effectively. As water resource and climate enthusiasts explore the SCS-Sallisaw Creek Site-29, they can appreciate the engineering feat behind this earth dam and the ongoing efforts needed to ensure its safety and reliability in the face of changing climate conditions.

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.
