Summary
It serves the primary purpose of flood risk reduction along the TR-West Owl Creek. With a dam height of 20 feet and a length of 900 feet, this structure has a storage capacity of 233 acre-feet and a maximum discharge rate of 640 cubic feet per second. Despite its low hazard potential, the risk assessment for this dam is classified as very high, emphasizing the importance of regular inspections and maintenance.
Managed by the Natural Resources Conservation Service, SCS-Owl Creek Site-05 features a controlled spillway and one outlet gate for water release. The dam is under the jurisdiction of the Oklahoma Water Resources Board and is subject to state permitting, inspection, and enforcement. Although the condition assessment is currently listed as "Not Rated," the dam has an inspection frequency of 5 years, with the last recorded inspection dating back to January 1980. While an Emergency Action Plan (EAP) is not mentioned, the risk management measures and inundation maps for the area are not specified, highlighting potential areas for improvement in emergency preparedness.
With its strategic location in Paoli, Oklahoma, SCS-Owl Creek Site-05 plays a crucial role in reducing flood risks and protecting the surrounding communities from potential water-related disasters. As climate change continues to impact water resources and extreme weather events become more frequent, the importance of well-maintained and regulated dams like this one cannot be overstated. Ongoing monitoring and timely maintenance are essential to ensure the safety and reliability of this vital infrastructure in the face of evolving environmental challenges.

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.
