Summary
C. Cadwell is a privately-owned earth dam located in Lumber City, Georgia, along Tr- Turnpike Creek. Built in 1980 by the Natural Resources Conservation Service, this dam serves multiple purposes including fish and wildlife pond, irrigation, and recreation. With a height of 16 feet and a length of 600 feet, the dam has a storage capacity of 240 acre-feet and a drainage area of 0.94 square miles.
Despite its moderate risk assessment rating of 3, S. C. Cadwell has a significant hazard potential due to its uncontrolled spillway type and lack of available condition assessment information. The dam's emergency action plan status, condition assessment date, and risk management measures are either not available or not up-to-date. With no associated structures and no recent inspection records, there is a need for improved oversight and maintenance to ensure the safety and reliability of this water resource infrastructure.
For water resource and climate enthusiasts, S. C. Cadwell presents an intriguing case study of a privately-owned dam in Georgia with a mix of recreational, ecological, and agricultural functions. The lack of detailed regulatory oversight and up-to-date maintenance records highlights the importance of proactive monitoring and risk management for ensuring the long-term resilience of water infrastructure in the face of changing environmental conditions. The unique location of this dam along Tr- Turnpike Creek adds to its ecological significance, making it a valuable site for further study and conservation efforts.

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.
