Summary
Completed in 1972, this earthen dam stands at a height of 52 feet and has a length of 1425 feet, providing a storage capacity of 2504 acre-feet. Situated on the TR-UNCLE JOHN CREEK, this dam has a controlled spillway and one valve outlet gate. The dam's hazard potential is rated as high, with a fair condition assessment.
Located in Canadian County, Oklahoma, the SCS-Uncle John Creek Site-08 is under the jurisdiction of the OWRB and is subject to state permitting, inspection, and enforcement. The dam's hydraulic height matches its structural height at 52 feet, with a maximum discharge of 5440 cubic feet per second. The risk assessment for this dam is very high (1), indicating the need for rigorous risk management measures to mitigate potential hazards. Although last inspected in 2011, the dam is still in fair condition and meets state regulatory standards.
Overall, the SCS-Uncle John Creek Site-08 serves a crucial role in flood risk reduction for the surrounding area, despite its high hazard potential. With its significant storage capacity and controlled spillway, this dam plays a key role in managing water resources in the region. As climate change continues to impact precipitation patterns and increase the frequency of extreme weather events, the importance of well-maintained infrastructure like the SCS-Uncle John Creek Site-08 cannot be overstated in safeguarding communities and ecosystems from potential flooding risks.

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.
