Summary

Completed in 1964, this dam stands at a height of 61 feet and has a storage capacity of 4556 acre-feet, with a normal storage level of 1237 acre-feet. The dam is situated on the Murry Creek, within the Tulsa District of Oklahoma, and is regulated by the OWRB.

Despite its low hazard potential, SCS-Rush Creek Site-015 is noted to have a very high risk assessment rating of 1, indicating potential vulnerabilities that need to be addressed. The dam features a controlled spillway with a width of 4 feet and an outlet gate with one valve. While the last inspection took place in 1980, the dam is required to undergo inspections every 5 years to ensure its structural integrity and safety measures are up to standard.

Water resource and climate enthusiasts will find SCS-Rush Creek Site-015 to be an intriguing case study in dam infrastructure and flood control measures. With its historical significance and ongoing regulatory oversight, this dam serves as a critical piece of infrastructure in managing water resources and mitigating flood risks in the Grady County area of Oklahoma.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
