Summary
Situated in Roger Mills County, the dam stands at a height of 32 feet with a hydraulic height of 28 feet and a length of 750 feet, providing a storage capacity of 460 acre-feet. With a controlled spillway and one outlet valve, the dam has a low hazard potential and has not been rated for condition assessment.
Located in HAMMON JUNTION along TR-NINEMILE CREEK, this dam is under the jurisdiction of the OWRB and falls within the Tulsa District. Despite its completion in the 1950s, the last inspection took place in 1980, with a scheduled inspection frequency of 5 years. While the risk assessment categorizes the dam's risk as "Very High (1)", further details on risk management measures and the dam's condition assessment are currently unavailable. With its critical purpose of flood risk reduction, this site serves as a vital infrastructure for managing water resources in the region.
Enthusiasts of water resources and climate will find SCS-Nine Mile Creek Site-07 an intriguing site to study, given its historical significance, structural details, and risk assessment. With its location in a high-risk area, the dam's management and maintenance play a crucial role in ensuring the safety and security of the surrounding communities. Further research and updates on the dam's condition assessment, risk management measures, and emergency action plans could provide valuable insights for policymakers and stakeholders in enhancing water resource management and climate resilience in 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.
