Summary
Constructed in 1966 by the USDA NRCS, this earth dam with a height of 26 feet and a hydraulic height of 23 feet serves the primary purpose of flood risk reduction along the TR-Turkey Creek. With its controlled spillway and a maximum storage capacity of 140 acre-feet, this dam plays a crucial role in managing floodwaters and protecting the surrounding area from potential inundation.
Despite its low hazard potential and a very high risk assessment rating, SCS-Tri-County Turkey Creek Site-18 has not been inspected since 1988. However, with state regulations in place and the Oklahoma Water Resources Board overseeing its permitting, inspection, and enforcement, the dam remains well-maintained and equipped to handle potential emergencies. As one of the many structures managed by the Natural Resources Conservation Service, this dam stands as a vital component of the state's water resource infrastructure, ensuring the safety and well-being of the local community in Duke.
As water resource and climate enthusiasts, the significance of SCS-Tri-County Turkey Creek Site-18 lies not just in its engineering and design but also in its role in mitigating flood risks and ensuring water security in the region. With its earth core and stone foundation, this dam exemplifies the importance of sustainable water management practices in safeguarding communities against the impacts of extreme weather events and climate change. As stewards of our environment, it is essential to recognize and appreciate the critical role that structures like SCS-Tri-County Turkey Creek Site-18 play in protecting our water resources and adapting to a changing climate.

Dam Data Reference
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.
