Summary
Completed in 1935, this earth dam spans 475 feet in length and reaches a height of 13 feet, with a storage capacity of 87 acre-feet. Situated along Spring Branch, the dam primarily serves a recreational purpose, offering a tranquil setting for visitors to enjoy water activities and scenic views.
Despite its low hazard potential, the T B Hallman Dam received an unsatisfactory condition assessment in 2017, highlighting the need for ongoing maintenance and monitoring to ensure its structural integrity. The dam's spillway type is uncontrolled, with a width of 0 feet, raising concerns about its ability to manage excess water flow during periods of heavy rainfall. With its risk assessment rated as moderate, the dam's management measures and emergency action plans are vital components in safeguarding the surrounding community from potential flooding events.
As a key feature in the Savannah District of the US Army Corps of Engineers, the T B Hallman Dam serves as a reminder of the intricate balance between water resource utilization and climate resilience. With a focus on recreation and water storage, this structure underscores the importance of proactive risk management and maintenance to mitigate potential hazards and ensure the long-term sustainability of our water infrastructure.

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.
