Summary
This earth dam stands at a height of 23 feet with a hydraulic height of 18 feet and a length of 1470 feet. It has a storage capacity of 185 acre-feet and a maximum discharge of 1470 cubic feet per second. The dam is equipped with a controlled spillway and one outlet gate for water management.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Mill Creek Site-13 indicates a very high risk level. The dam has not been rated for its condition assessment, and the last inspection was conducted in 1980 with a scheduled inspection frequency of every five years. Emergency preparedness measures such as an Emergency Action Plan (EAP) and inundation maps have not been reported. The dam is not owned or funded by any federal agency, and its operations are not overseen by any federal entity, indicating a greater reliance on state-level regulatory agencies for enforcement and inspection.
Water resource and climate enthusiasts will find SCS-Mill Creek Site-13 to be an intriguing case study in dam infrastructure management and emergency preparedness. The dam's location on TR-Mill Creek in the Fort Worth District presents unique challenges and opportunities for flood risk reduction in the region. With its historic construction date and limited inspection history, there is a need for increased attention to maintenance and monitoring to ensure the safety and stability of this critical water resource infrastructure in Oklahoma.

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.
