Summary
Constructed in 2005 by the Natural Resources Conservation Service, the dam stands at a height of 15.3 feet and has a storage capacity of 70.6 acre-feet. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
Located within the Jacksonville District of Georgia, Osteen Lake Dam is not regulated by the state and does not require permits or inspections. The dam features an uncontrolled spillway and outlet gates, with no associated locks or drainage area. Despite being unregulated, the dam has a moderate risk rating of 3 and has no emergency action plan in place as of the last inspection in July 2020.
For water resource and climate enthusiasts, Osteen Lake Dam serves as an interesting case study of a privately owned irrigation dam with minimal state oversight. With a focus on water storage and management, this dam provides valuable insights into the challenges and responsibilities associated with maintaining and monitoring infrastructure in a changing climate. As efforts to address water scarcity and climate resilience continue to grow, Osteen Lake Dam highlights the importance of proactive risk management and emergency preparedness in safeguarding our water resources.

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.
