Summary
Completed in 1963, this earth dam stands at a height of 25 feet with a hydraulic height of 32 feet, offering a storage capacity of 1,125 acre-feet. With a spillway width of 258 feet and a maximum discharge of 2,290 cubic feet per second, this dam serves multiple purposes including fire protection, stock or small fish pond, and flood risk reduction.
Managed by the Texas Commission on Environmental Quality, the Tehuacana Creek WS SCS Site 20 Dam is subject to state regulations, inspections, and enforcement to ensure its safety and functionality. The dam features one slide (sluice gate) and two uncontrolled outlet gates, with a drainage area of 1.82 square miles and a surface area of 31 acres. While the hazard potential and condition assessment are not available, the risk assessment indicates a moderate level of risk (3), prompting the need for ongoing risk management measures to ensure the dam's resilience in the face of potential emergencies.
As part of the Fort Worth District, this dam plays a crucial role in mitigating flood risks and protecting the surrounding community. With a focus on emergency preparedness and risk management, the Tehuacana Creek WS SCS Site 20 Dam stands as a vital infrastructure for water resource and climate enthusiasts to study and appreciate in the context of sustainable water management practices.

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.
