Summary
Completed in 1950, this earth dam stands at a height of 24 feet and has a hydraulic height of 20 feet, with a capacity to store up to 802 acre-feet of water. This controlled spillway structure spans 1300 feet and has a surface area of 38 acres, serving as a vital component in managing water resources in the region.
The dam, situated on TR-Mill Creek, is under the jurisdiction of the Oklahoma Water Resources Board and is inspected regularly to ensure its functionality and safety. Despite being classified as low hazard potential, the risk assessment for SCS-Mill Creek Site-08 indicates a very high risk level (1). With one valve outlet gate and a stone core foundation, this dam plays a crucial role in mitigating flood risks and protecting the surrounding communities from potential inundation events.
In the event of an emergency, the dam's Emergency Action Plan preparedness status and risk management measures remain unspecified. Nevertheless, with its strategic location and design features, SCS-Mill Creek Site-08 continues to be a key infrastructure asset for water resource management and climate resilience efforts in the area, contributing to overall environmental sustainability and community safety.

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.
