Summary

Completed in 1961, this earth dam stands at a height of 90 feet and serves primarily for hydroelectric purposes, with a storage capacity of 306,400 acre-feet and a surface area of 30,200 acres. Located in Cherokee County, this dike on the Coosa River is essential for managing water resources and providing recreational opportunities in the area.

With a high hazard potential, the Weiss - Highway 411 Dike is subject to regular inspections and emergency preparedness strategies. The structure has a risk assessment rating of 2, indicating a high level of risk that requires proactive risk management measures. Despite its critical role in water resource management, the dam's condition assessment is currently unavailable, suggesting a need for further evaluation and maintenance to ensure its long-term functionality and safety. Climate and water resource enthusiasts can appreciate the complex interplay of infrastructure, regulation, and environmental stewardship embodied by the Weiss - Highway 411 Dike as a vital component of the region's hydroelectric system.

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.
