Summary

This earth dam, completed in 1966, stands at a height of 37 feet and spans a length of 770 feet. With a storage capacity of 2,832 acre-feet, it primarily serves the purpose of flood risk reduction along the Flatrock Branch river.

Managed by the local government and regulated by the Georgia SAFE DAMS PROGRAM, Bull Creek WS Str # 21 poses a high hazard potential but is currently rated as satisfactory in condition assessment. The dam's inspection frequency is set at 2 years, with the last assessment conducted in January 2017. Despite its moderate risk assessment level, the structure meets regulatory guidelines and plays a vital role in water resource management within the region.

Water resource and climate enthusiasts will find Bull Creek WS Str # 21 an interesting subject for study, given its strategic location and critical role in flood risk reduction. As a key part of the local water infrastructure, this dam provides essential storage capacity and helps mitigate potential hazards along the Flatrock Branch. With its historical significance and ongoing maintenance, Bull Creek WS Str # 21 stands as a testament to effective water management practices in Georgia.

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.
