Summary
Built in 1982 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the Turkey Creek. With a height of 34 feet and a length of 2470 feet, it has a storage capacity of 2679 acre-feet and covers a surface area of 90 acres.
Despite being classified with a low hazard potential, the dam's risk assessment is very high, indicating the need for proactive risk management measures. The controlled spillway with a width of 2 feet helps regulate the maximum discharge of 9220 cubic feet per second. The dam's condition is currently not rated, and it has not undergone inspection since January 1980, highlighting the importance of regular monitoring and maintenance to ensure its structural integrity and effectiveness in managing flood events.
Enthusiasts focused on water resources and climate in the region can find value in studying the SCS-Tri-County Turkey Creek Site-01 as an example of flood risk reduction infrastructure. The dam's location in Duke, Oklahoma, along with its affiliation with the OWRB and USDA NRCS, provides insights into state and federal agency involvement in water resource management. As climate change impacts continue to pose challenges to water infrastructure, understanding the design, purpose, and risk profile of dams like this one is crucial for sustainable water resource planning and resilience in the face of increasing extreme weather events.

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.
