Summary
The dam, with a height of 25 feet and a hydraulic height of 22 feet, is an earth-type structure with a stone core and soil foundation. It has a Normal Storage capacity of 66 acre-feet and a Hazard Potential rated as low.
Managed by the Oklahoma Water Resources Board (OWRB), this dam on TR-Turkey Creek falls under state regulation, permitting, inspection, and enforcement. While the dam has not been rated for its condition, it is regularly inspected every 5 years, with the last inspection dating back to 1980. Despite its low hazard potential, the Risk Assessment for this site is categorized as Very High (1), indicating potential risks that need to be closely monitored and managed. Additionally, the dam has a controlled spillway and one valve outlet gate.
Overall, SCS-Tri-County Turkey Creek Site-14c serves as a crucial infrastructure for flood risk reduction in the region, highlighting the importance of proper maintenance and risk management to ensure the safety and efficiency of the dam in protecting the surrounding area from potential flooding events. The data showcases the collaborative efforts between state agencies and federal designers in safeguarding water resources and climate resilience in Oklahoma.

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.
