Summary

This private earth dam stands at a height of 23 feet and spans 640 feet in length, with a storage capacity of 189 acre-feet. The dam overlooks Thompson Creek and has a surface area of 14 acres, providing a serene environment for water resource and climate enthusiasts to explore.

While the dam has a low hazard potential, its risk assessment is moderate, emphasizing the need for ongoing monitoring and maintenance. The dam is not currently regulated by the state but undergoes regular inspections, with the last one conducted in March 2017. The dam's spillway is uncontrolled, and it has uncontrolled outlet gates, contributing to its recreational purpose and overall functionality for the community in the Towalaga Community of Henry, Georgia.

As a significant part of the local landscape, Lake Hampton Dam offers a glimpse into the intersection of water resource management and recreational activities. With its moderate risk assessment and low hazard potential, the dam provides a safe environment for visitors to enjoy the beauty of nature while highlighting the importance of ongoing monitoring and maintenance to ensure its continued operation. For water resource and climate enthusiasts, Lake Hampton Dam serves as a fascinating example of how infrastructure can harmoniously coexist with natural surroundings, creating a unique and valuable recreational space in Henry, Georgia.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
