Jones Lake Dam Reservoir Report
Nearby: Duggan Lake Dam Lake Dow North Dam
Last Updated: February 21, 2026
Jones Lake Dam, located in Henry, Georgia, was completed in 1975 and serves multiple purposes including fire protection and as a small fish pond.
Summary
The earth dam stands at a height of 24 feet and has a length of 370 feet, with a storage capacity of 129 acre-feet. Despite being privately owned and not regulated by the state, the dam has a low hazard potential and a moderate risk assessment rating.
Although the dam is primarily uncontrolled, with an uncontrolled spillway and outlet gates, it is inspected every 5 years to ensure its structural integrity. The condition assessment of Jones Lake Dam is currently listed as "Not Rated," indicating a need for further evaluation. The surrounding area has a drainage area of 340 acres, with a surface area of 9 acres and a normal storage capacity of 72 acre-feet. The dam's risk management measures and emergency action plan status are not currently available, highlighting the importance of ongoing monitoring and maintenance for this critical water resource infrastructure.

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.
