Summary
Completed in 1960, this dam stands at 51 feet tall and spans a length of 2150 feet, with a storage capacity of 905 acre-feet. With a spillway width of 2 feet and a maximum discharge of 6500 cubic feet per second, this dam plays a crucial role in managing floodwaters and protecting the surrounding area from potential inundation.
This high-hazard potential dam, with a very high risk assessment rating, is equipped with a single valve outlet gate for controlled water release. Although its condition assessment is listed as "Not Rated," the dam remains under state inspection, permitting, and enforcement, ensuring its continued safety and functionality. Despite being decades old, this structure serves as a testament to effective water resource management and the importance of proactive dam maintenance to mitigate potential risks and protect downstream communities.
As one of the many essential flood risk reduction structures in Oklahoma, SCS-Turkey Creek Site-10 highlights the collaborative efforts between state agencies, federal designers, and local communities to safeguard against the impacts of extreme weather events and changing climate patterns. With its strategic location and design features, this dam stands as a critical asset in the region's water resource infrastructure, demonstrating the ongoing commitment to resilience and adaptation in the face of a changing climate.

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.
