Summary
The dam, classified as a buttress type, was last inspected in May 2017 with a low hazard potential rating. Despite being uncontrolled, the dam boasts a moderate risk assessment score of 3, prompting the need for regular inspections every five years.
Situated within the Savannah District, Crosby Lake Dam has no state regulation but falls under the jurisdiction of Georgia. With its uncontrolled spillway and outlet gates, the dam poses a moderate risk that requires ongoing risk management measures. Although the condition of the dam is currently not rated, its strategic location and potential impact on the local environment make it a point of interest for water resource and climate enthusiasts seeking to understand the complexities of managing and maintaining critical infrastructure in the face of evolving climate conditions.
For those passionate about water resources and climate resilience, Crosby Lake Dam serves as a case study in the intricacies of balancing private ownership with public safety and environmental considerations. As climate change continues to pose challenges to existing infrastructure, the need for proactive risk assessment and management measures at dams like Crosby Lake becomes increasingly vital in ensuring the sustainable management of water resources for future generations.

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.
