Summary

This private earth dam stands at 16 feet high and spans 320 feet in length, serving primarily for recreational purposes. With a storage capacity of 93 acre-feet, the dam has a low hazard potential and moderate risk assessment rating.

The dam features an uncontrolled spillway with a width of 24 feet, capable of handling a maximum discharge of 18 cubic feet per second. Despite its age, the condition assessment of Black's Dam is currently not available, with no recent inspection data provided. The dam has not undergone any modifications or inspections in recent years, presenting a potential area of concern for water resource and climate enthusiasts.

Located just 22 miles from Atlanta, Black's Dam provides a tranquil recreational spot along the Chattahoochee River, offering opportunities for fishing, boating, and other outdoor activities. While the dam may not pose an immediate threat, its lack of recent assessment and maintenance highlights the importance of ongoing monitoring and management of water infrastructure to ensure public safety and environmental sustainability in the face of changing climate conditions.

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.
