Summary
This earth dam, with a height of 15.5 feet and a hydraulic height of 15.7 feet, creates a reservoir with a storage capacity of 132 acre-feet and a surface area of 12.9 acres. The dam, completed in an unknown year, serves as a low hazard potential structure with a moderate risk assessment rating of 3.
Although the dam is not regulated by the state of Georgia, it is subject to periodic inspections, with the last one conducted in July 2016. The dam's spillway type is uncontrolled, and it features uncontrolled outlet gates. Despite its unregulated status, the dam's condition remains unrated, and it has not been assigned an Emergency Action Plan (EAP). However, the risk management measures in place are moderate, indicating a level of preparedness for potential emergencies.
Water resource and climate enthusiasts may find Tison Lake Dam intriguing for its recreational purpose and modest size. The dam's location in Worth County, Georgia, within the Mobile District, offers a peaceful retreat for outdoor activities such as fishing and boating. While the dam's regulatory oversight may raise questions about its safety and maintenance, the moderate risk assessment suggests that appropriate measures are in place to address potential hazards. Overall, Tison Lake Dam presents an interesting case study for those interested in the intersection of water resource management and recreational infrastructure.

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.
