Summary
Completed in 1974, the dam stands at a height of 30 feet and has a storage capacity of 650 acre-feet. Situated on TR-Copperas Creek, the dam plays a crucial role in providing water for agricultural needs in the region.
Managed by the Texas Commission on Environmental Quality (TCEQ), South Gibson Dam is regulated and inspected by the state, ensuring its structural integrity and compliance with safety standards. Despite being rated as having a high risk potential, the dam has not been assessed for condition or emergency preparedness in recent years. With no spillway and limited information on its drainage area, the dam's impact on water resource management and climate resilience in the area remains a subject of interest for enthusiasts.
For water resource and climate enthusiasts, South Gibson Dam offers a unique case study in the intersection of irrigation infrastructure and environmental monitoring. The dam's history, design, and current state raise questions about its long-term sustainability and the potential risks it poses to the surrounding ecosystem. As stakeholders continue to assess and manage the dam's operations, its role in supporting agricultural activities while maintaining ecological balance will be closely monitored.

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.
