Summary
The dam stands at a height of 20 feet with a hydraulic height of 16 feet, and a length of 2300 feet. Its primary purpose is flood risk reduction, with a storage capacity of 223 acre-feet and a surface area of 29 acres.
The dam features a controlled spillway, one valve outlet gate, and is classified as having a low hazard potential. Despite being last inspected in 1988, with a 5-year inspection frequency, its condition is currently not rated. The risk assessment for SCS-Tri-County Turkey Creek Site-29b identifies a very high risk level (1), emphasizing the importance of ongoing monitoring and maintenance to ensure the safety and integrity of the structure for the surrounding community and environment.
With the state of Oklahoma having jurisdiction over the dam, and the OWRB serving as the state regulatory agency, it is crucial for all stakeholders to remain vigilant in implementing risk management measures and staying prepared for potential emergencies. As enthusiasts of water resources and climate, understanding and advocating for the proper maintenance and oversight of structures like SCS-Tri-County Turkey Creek Site-29b is vital in safeguarding our water systems and communities against the impacts of extreme weather events and changing climate patterns.

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.
