Summary
This earthen dam, designed by the USDA NRCS, was completed in 1960 with a primary purpose of flood risk reduction along the Turkey Creek. Standing at a height of 46 feet and with a hydraulic height of 41 feet, the dam spans 3,380 feet in length and has a storage capacity of 1,975 acre-feet.
Managed by the Oklahoma Water Resources Board (OWRB), SCS-Turkey Creek Site-06 is regulated, permitted, inspected, and enforced by the state. The dam's hazard potential is classified as significant, with a fair condition assessment. In the event of an emergency, the dam is equipped with one valve outlet gate and a controlled spillway with a width of 4 feet. The risk assessment for this dam is very high, necessitating a thorough risk management strategy to ensure the safety of surrounding communities and the integrity of the structure.
For water resource and climate enthusiasts, SCS-Turkey Creek Site-06 presents an intriguing case study in dam management and flood risk reduction. With its historical significance, structural details, and state regulatory oversight, this dam serves as a vital component of water resource management in Oklahoma. As efforts continue to address the high-risk nature of the dam and implement necessary risk management measures, the importance of sustainable water infrastructure becomes increasingly apparent in the face of changing climate patterns and growing populations that rely on the protection and regulation of water resources.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
