Summary
Completed in 1958, this dam stands at 18 feet high and has a storage capacity of 150 acre-feet. With a controlled spillway and a low hazard potential, the dam has a very high risk assessment rating, highlighting its importance in managing potential flooding events in the area.
Managed by the Oklahoma Water Resources Board (OWRB), SCS-Mill Creek Site-07 is equipped with a single valve outlet gate for water release. Despite its last inspection dating back to 1980, the dam's condition remains unrated, emphasizing the need for updated assessments to ensure its structural integrity and functionality during emergency situations. With a maximum discharge capacity of 532 cubic feet per second, this dam plays a crucial role in mitigating flood risks and protecting the surrounding community and environment.
As climate change continues to impact water resources and intensify extreme weather events, the significance of SCS-Mill Creek Site-07 as a flood control infrastructure cannot be understated. With its strategic location in Murray County, Oklahoma, and its role in reducing flood risks along TR-Mill Creek, this dam serves as a vital component in the state's water management system. Moving forward, regular inspections, maintenance, and risk management measures will be essential to ensure the continued effectiveness and safety of this critical water resource infrastructure.

Dam Data Reference
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.
