Summary
The dam stands at a height of 10.5 feet, with a hydraulic height of 8.9 feet and a length of 156 feet. It has a storage capacity of 138 acre-feet, providing a normal storage capacity of 50.6 acre-feet. The dam is primarily an earth-type structure with a buttress core, designed by an unknown entity.
Despite being privately owned, the Webb Lake Dam is subject to state jurisdiction and inspection. It has been deemed to have a low hazard potential, with a moderate risk assessment rating of 3 out of 5. The dam's condition is currently not rated, and it has not been evaluated for its emergency action plan preparedness. The surrounding area boasts a surface area of 18.4 acres and a drainage area of 73 square miles, making it an important landmark for both water resource and climate enthusiasts in the region.
Overall, Webb Lake Dam presents an intriguing case study for water resource and climate enthusiasts, with its unique design features and operational characteristics. As a privately-owned structure under state jurisdiction, it plays a crucial role in managing water resources in the Gordon County area. Its moderate risk assessment rating highlights the importance of ongoing monitoring and evaluation to ensure the safety and effectiveness of the dam 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.
