Scs-Sallisaw Creek Site-01 Reservoir Report

Last Updated: December 5, 2025

Located in Sallisaw, Oklahoma, the SCS-Sallisaw Creek Site-01 is a state-regulated earth dam designed by the USDA NRCS in 1963 for flood risk reduction along the TR-Sallisaw Creek.

Summary

The dam stands at a height of 23 feet with a length of 700 feet, providing a maximum storage capacity of 252 acre-feet and a normal storage of 120 acre-feet. With a controlled spillway and a hazard potential rated as low, this dam plays a crucial role in managing water resources and mitigating flood risks in the area.

Managed by the Oklahoma Water Resources Board, the SCS-Sallisaw Creek Site-01 is regularly inspected with a frequency of 5 years to ensure its structural integrity and safety. Despite being deemed as "Not Rated" in terms of condition assessment, the dam's risk assessment is categorized as "Very High (1)", highlighting the importance of ongoing monitoring and maintenance. With a valve outlet gate and no associated structures, this dam serves as a vital infrastructure for water management and protection against potential flooding events in the region.

As part of the flood risk reduction infrastructure in Sequoyah County, the SCS-Sallisaw Creek Site-01 plays a critical role in safeguarding the surrounding communities and water resources. With a designated emergency action plan (EAP) and risk management measures in place, this dam exemplifies the collaboration between federal and state agencies to ensure the resilience of water infrastructure in the face of climate variability and changing hydrological 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.
