Summary
This earth dam stands at a height of 36 feet with a hydraulic height of 31 feet, and a structural height of 36 feet, spanning a length of 730 feet. The dam has a storage capacity of 204 acre-feet, with a normal storage capacity of 65 acre-feet, and a maximum discharge of 3720 cubic feet per second.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Nine Mile Creek Site-06 indicates a very high risk level (1). The dam is equipped with a controlled spillway and a single valve outlet gate. The last inspection of the site was conducted on January 1, 1980, with an inspection frequency of 5 years. The overall condition of the dam is currently listed as "Not Rated," and there is no Emergency Action Plan (EAP) in place.
Water resource and climate enthusiasts interested in the management and maintenance of dams for flood risk reduction in Oklahoma may find SCS-Nine Mile Creek Site-06 to be a compelling case study. With its unique design features and risk assessment profile, this dam serves as a noteworthy example of infrastructure aimed at protecting communities and the environment from the impacts of extreme weather events.

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.
