Summary

This private earth dam stands at 15 feet tall and spans 450 feet in length, creating a surface area of 34.2 acres and a storage capacity of 300 acre-feet. The dam is situated on Mill Creek and is under the jurisdiction of the Fort Worth District of the US Army Corps of Engineers.

Despite its primary purpose for recreation, Coca Cola Lake Dam is classified as having a significant hazard potential. The dam has not been rated for its condition assessment, and there is no information available on its emergency action plan or risk management measures. With no state regulation or inspection in place, it is crucial for stakeholders to monitor the dam's integrity and ensure safety measures are in place to prevent potential risks to the surrounding area.

As water resource and climate enthusiasts visit Coca Cola Lake Dam for recreational activities, it is essential for them to be aware of the dam's significant hazard potential and the lack of state oversight. By staying informed and advocating for proper maintenance and emergency preparedness, visitors can help ensure the safety and longevity of this important water resource infrastructure in Miller County, Arkansas.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
