Summary
Built in 1979 by designer Rex Miller, this dam primarily serves the purpose of irrigation for agricultural needs in the area. Standing at a height of 13 feet with a hydraulic height of 12.5 feet, the dam has a storage capacity of 145 acre-feet and covers a surface area of 19 acres.
Despite being unregulated by the state, Tillman Irrigation Pond #2 has been inspected periodically, with the last inspection conducted in May 2014. The dam has a low hazard potential and is currently rated as 'Not Rated' in terms of condition assessment. While the risk assessment deems it as moderate, the dam is not under the jurisdiction of the US Army Corps of Engineers. With an uncontrolled spillway and outlet gates, this dam serves as a vital resource for maintaining water levels for irrigation purposes in the region.
For water resource and climate enthusiasts, Tillman Irrigation Pond #2 offers a glimpse into the intricate infrastructure supporting agricultural activities in rural Georgia. With its modest size and uncontrolled spillway, the dam stands as a testament to the importance of water management in sustaining crop production. Despite its low hazard potential, the dam's risk assessment and condition remain to be closely monitored to ensure its continued functionality in the face of changing climate patterns and water resource demands.

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.
