Summary

Designed by W. R. HOLWAY & ASSOCIATES, this earth dam serves multiple purposes, including flood risk reduction and hydroelectric power generation. Completed in 1964, it stands at a height of 45 feet and has a maximum storage capacity of 565,674 acre-feet, with a normal storage level of 215,000 acre-feet.

With a hazard potential rated as high, Salina Dike is under state regulation and inspection, ensuring its safety and functionality. The dam, situated on the Neosho River, covers a surface area of 11,000 acres and has a drainage area of 11,437 square miles. Despite not having a spillway, it plays a crucial role in managing water resources in the region and contributing to flood control efforts.

Maintained and monitored by the Federal Energy Regulatory Commission, Salina Dike is a vital piece of infrastructure in the area. Its strategic location and design make it a key asset for water resource management and climate resilience efforts in Mayes County, Oklahoma. As an essential component of the region's water infrastructure, Salina Dike highlights the importance of sustainable dam operations and risk management in the face of changing environmental 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.
