Summary
The dam stands at a height of 14.5 feet and covers a surface area of 23.2 acres, making it a significant asset for water supply and irrigation in the region. While the dam's hazard potential is currently undetermined, its condition assessment is not rated, highlighting the need for further evaluation and maintenance to ensure its long-term reliability.
Managed by the Savannah District of the US Army Corps of Engineers, the Williamson Irrigation Dam serves an essential role in water management for the local community. Despite its critical function, the dam's inspection frequency, emergency preparedness, and risk assessment measures are not currently specified. As climate change continues to impact water resources, it is essential for stakeholders to prioritize monitoring and maintenance efforts to safeguard the dam's structural integrity and optimize its performance in the face of evolving environmental conditions.
As water resource and climate enthusiasts, understanding the importance of structures like the Williamson Irrigation Dam is crucial in addressing the challenges posed by changing weather patterns and increasing water demands. By staying informed about the dam's condition, maintenance needs, and emergency response plans, passionate individuals can contribute to the sustainable management of water resources in the region and help ensure the resilience of critical infrastructure in the face of climate-related threats.

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.
