Summary

Crownover with a primary purpose of recreation. Completed in 2004, this dam stands at a height of 25 feet and has a storage capacity of 44.2 acre-feet, providing ample opportunities for outdoor activities in the area.

With a low hazard potential and a moderate risk assessment rating, Long Branch Lake Dam has not been rated for its condition assessment. Despite being uninspected since March 2018, the dam's emergency action plan status and risk management measures remain unreported. However, it is reassuring to note that the dam is equipped with uncontrolled spillways and outlet gates as part of its safety features.

This picturesque dam, nestled in Walker County, Georgia, is a popular spot for water resource and climate enthusiasts to enjoy the serene surroundings and recreational opportunities it offers. While it may not be regularly inspected or monitored, the low hazard potential and moderate risk assessment indicate that Long Branch Lake Dam continues to be a safe and inviting destination for visitors to experience the beauty of nature in this charming corner of the state.

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.
