Summary
Completed in 1958, this dam stands at 25 feet tall with a hydraulic height of 20 feet and a length of 1510 feet. It has a storage capacity of 458 acre-feet and a surface area of 39 acres.
Despite being classified as low hazard potential with a very high risk assessment rating, the condition of SCS-Mill Creek Site-01 has not been rated. The dam features a controlled spillway and a single valve outlet gate. While it has not been inspected since 1980, it is subject to regular inspections every 5 years. The dam is situated in a picturesque location in Hickory, Oklahoma, with Tom Cole being the representative for the area.
Water resource and climate enthusiasts will be intrigued by the engineering and design of SCS-Mill Creek Site-01, as well as its role in mitigating flood risks in the region. With its historical significance and unique features, this earth dam serves as a key component in the management of water resources along Mill Creek. The data available on this site provides valuable insights into its construction, purpose, and potential risks, making it a focal point for further study and analysis in the field.

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.
