Summary
8, also known as Goldmine Lake, stands as a vital flood risk reduction measure within the region. Built in 1957 by the Natural Resources Conservation Service, this earth dam with a height of 56.2 feet serves to protect the area from potential flooding events along Goldmine Branch. The dam has a storage capacity of 1924 acre-feet and covers a surface area of 20.8 acres.
Despite its essential role in flood control, Structure No. 8 poses a high hazard potential due to its poor condition as assessed in August 2018. With an inspection frequency of every two years, the dam requires immediate attention to ensure its continued functionality and safety for the surrounding community. The Georgia-SAFE DAMS Program oversees the regulatory aspects of the dam, including permitting, inspection, and enforcement, highlighting the state's commitment to maintaining the integrity of its water resource infrastructure.
As water resource and climate enthusiasts, understanding the significance of Structure No. 8 within the Pumpkinvine Creek Watershed sheds light on the intersection of human development and natural ecosystems. With its historical construction dating back over six decades, the dam serves as a reminder of the ongoing need for sustainable water management practices and proactive maintenance to mitigate potential risks and safeguard the environment and communities downstream. Through collaborative efforts between state agencies and stakeholders, the preservation of this critical infrastructure will be essential in ensuring the long-term resilience of the region in the face of evolving climate challenges.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
