Summary
2 Lake Dam, also known as Arms Lake #2 Dam, is a private-owned structure located in Lamar, Georgia, near the city of Bethel Church Environs. Completed in 1975, this earthen dam stands at a height of 32.6 feet and stretches for 460 feet, serving primarily for recreational purposes. With a storage capacity of 111 acre-feet and a surface area of 7 acres, the dam contributes to the drainage of a 110-acre watershed area.
Despite being unregulated by the state, Colwell No. 2 Lake Dam poses a low hazard potential and has not been rated for its condition. However, it undergoes regular inspections every 5 years, with the last one conducted in April 2020. The dam features an uncontrolled spillway and outlet gates, with no associated locks. The risk assessment for this structure deems it to have a moderate risk level, with no specific risk management measures outlined. Overall, Colwell No. 2 Lake Dam presents an interesting case for water resource and climate enthusiasts, showcasing a balance between recreational usage and potential risk management considerations.

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.
