Summary

Managed by the US Army, this earth dam structure has a height of 49 feet and a storage capacity of 867 acre-feet, providing ample opportunities for outdoor activities and water-based recreation in the area. The reservoir is fed by Estaboga Creek and covers a surface area of 32 acres, offering a serene escape for water resource and climate enthusiasts.

With a spillway width of 52 feet and a maximum discharge capacity of 4083 cubic feet per second, Cone Reservoir poses a hazard potential classified as high, although its risk assessment is considered moderate. The dam's condition assessment is currently listed as not available, and its last inspection was conducted in June 2016. Despite these factors, the reservoir remains a popular destination for locals and visitors alike, showcasing the importance of sustainable water resource management in the face of climate challenges. Whether you're seeking outdoor adventures or simply a tranquil spot to appreciate nature, Cone Reservoir promises a scenic retreat in the heart of Alabama's natural beauty.

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.
