Summary
This private Earth dam stands at a height of 30 feet and stretches 210 feet in length, providing a storage capacity of 34 acre-feet and covering a surface area of 43 acres. The dam's design, classified as Buttress core type, ensures its structural integrity for irrigation purposes.
Despite being privately owned and not regulated by the state, Rosen Lake Dam has a low hazard potential and a moderate risk assessment rating of 3. Although its condition assessment is currently listed as "Not Rated," the dam has been inspected periodically, with the last recorded inspection in June 2004. The dam's uncontrolled spillway and outlet gates further contribute to its low hazard potential, making it a relatively stable and manageable structure for water resource and climate enthusiasts to observe and study in the region.
Overall, Rosen Lake Dam serves as a vital infrastructure for irrigation purposes in the area, showcasing the importance of sustainable water resource management. Its location in Georgia and relatively low hazard potential make it an intriguing case study for enthusiasts interested in the intersection of water resources, climate, and infrastructure maintenance. Further monitoring and assessment of the dam's condition and risk management measures will be essential for ensuring its long-term sustainability and functionality.

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.
