Summary
Completed in 1999, this earth dam stands at a height of 18 feet and has a length of 1200 feet, providing a storage capacity of 176 acre-feet. With a low hazard potential and a moderate risk assessment rating, the dam is classified as uncontrolled with an inspection frequency of 5 years.
Located within the Savannah District of the USACE, Bass Lake Dam is not regulated by the state but undergoes regular inspections to ensure its structural integrity. Despite being unlisted/unknown, the dam's foundations and core type are buttress and earth, respectively. The dam's spillway type is uncontrolled, and it has an uncontrolled outlet gates system. The last inspection was conducted in March 2010, and the dam's condition assessment remains unrated.
Water resource and climate enthusiasts interested in Bass Lake Dam will find it to be a vital irrigation structure in Georgia. While deemed to have a low hazard potential, the dam's moderate risk assessment suggests the need for ongoing monitoring and maintenance to ensure the safety and effectiveness of its operations. Given its private ownership and purpose, Bass Lake Dam plays a crucial role in supporting agricultural activities in the region, highlighting the significance of sustainable water resource management in the face of climate challenges.

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.
