Summary
Completed in 1956, this dam stands at a height of 23 feet and has a storage capacity of 135 acre-feet. The dam spans a length of 1040 feet and is equipped with a controlled spillway to manage maximum discharges of up to 620 cubic feet per second.
Despite its low hazard potential, SCS-Owl Creek Site-10 poses a very high risk, with a DSAC-assigned risk rating of 1. While the dam's condition assessment is currently listed as "Not Rated," it is subject to regular inspections every 5 years. The dam is equipped with a valve outlet gate and has not been modified since its completion. Although the emergency action plan (EAP) status and risk management measures are not specified, the dam's location on TR-WEST OWL CREEK underscores its importance in protecting the surrounding area from potential flooding events.
Water resource and climate enthusiasts will find SCS-Owl Creek Site-10 to be a significant infrastructure project in Oklahoma, designed to mitigate flood risks and protect the local community. The dam, owned by the state, serves as a critical flood control measure, showcasing the collaborative efforts between government agencies and the USDA NRCS in safeguarding water resources and enhancing resilience to extreme weather events. Despite its age, the dam's structural integrity and operational effectiveness are key factors in maintaining public safety and preserving the ecological balance of the region.

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.
