Summary
Completed in 1956, this dam stands at a height of 27 feet and has a storage capacity of 269 acre-feet. With a controlled spillway and a valve outlet gate, the dam serves the primary purpose of flood risk reduction, protecting the surrounding area from potential inundation.
Despite being rated as having low hazard potential, the risk assessment for SCS-Owl Creek Site-09 indicates a very high risk level due to its location and structural characteristics. The dam has not been inspected since 1980, though it is scheduled for inspections every 5 years. The dam is in a condition that has not been rated, highlighting the need for a comprehensive assessment to ensure its continued effectiveness in mitigating flood risks in the region.
With its stone core and soil foundation, SCS-Owl Creek Site-09 plays a crucial role in managing water resources and climate-related challenges in the area. As an essential piece of infrastructure owned by the state of Oklahoma and regulated by the OWRB, this dam underscores the importance of ongoing monitoring and maintenance to safeguard against potential hazards and ensure its continued functionality for the community.

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.
