Summary
Lake Dam 4 W, is a state-owned structure located in McDuffie, Georgia. Built in 1952, this earth dam stands at a height of 22 feet and has a length of 330 feet. Its primary purpose is listed as 'Other' with a storage capacity of 225 acre-feet and a normal storage of 172 acre-feet. The dam is situated on the Fort Branch river and has a drainage area of 538 square miles.
This low hazard potential dam has not been rated for its condition assessment, but it has undergone inspections every 5 years, with the last one being conducted in May 1997. The risk assessment for Dearing # 10 Lake Dam is moderate (3), indicating a moderate level of risk associated with the structure. Despite being unregulated by the state and having uncontrolled spillways and outlet gates, the dam has not raised significant concerns regarding its safety. For water resource and climate enthusiasts, this dam presents an opportunity to study and monitor the impact of its operations on the surrounding environment and water systems.
While not under the jurisdiction of the state regulatory agency, Dearing # 10 Lake Dam in McDuffie, Georgia, remains an essential part of the local ecosystem. With its historical significance dating back to 1952, this earth dam serves as a focal point for water resource and climate enthusiasts interested in understanding the dynamics of dam structures and their interaction with the natural environment. As the risk assessment suggests a moderate level of risk, ongoing monitoring and assessment of the dam's condition are crucial to ensure the safety of the surrounding area and its residents.

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.
