Summary
Built in 1975, this private earth dam spans 660 feet in length and reaches a height of 16.6 feet, with a storage capacity of 147 acre-feet. While it poses a low hazard potential, its risk assessment is moderate, highlighting the importance of regular inspections and maintenance to ensure its structural integrity.
Managed by private owners, Derris Jones Lake Dam No 2 is not regulated by the state but undergoes periodic inspections to ensure compliance with safety standards. With a drainage area of 95 square miles and a normal storage capacity of 60 acre-feet, this dam plays a crucial role in supporting agricultural activities in the surrounding areas. Despite its uncontrolled spillway and outlet gates, the dam's condition remains unrated, emphasizing the need for ongoing risk management measures to mitigate potential hazards.
Although not under the jurisdiction of federal agencies, Derris Jones Lake Dam No 2 serves as a key infrastructure for water resource management in Tift County, Georgia. As climate change impacts water availability and quality, it is essential to prioritize the maintenance and monitoring of dams like this to ensure sustainable water use and resilience in the face of changing environmental conditions.

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.
