Summary
This earth dam stands at a height of 23 feet and spans 1200 feet, with a storage capacity of 665 acre-feet and a drainage area of 0.8 square miles. The dam's primary purpose is flood risk reduction, serving as a vital defense against potential flooding events in the region.
Managed by local government authorities and regulated by the Texas Commission on Environmental Quality (TCEQ), the Tehuacana Creek WS SCS Site 23 Dam is equipped with an uncontrolled spillway and two outlet gates to manage water flow. Despite being rated as "Not Available" in terms of hazard potential and condition assessment, the dam is subject to regular inspections every 5 years to ensure its structural integrity and operational efficiency. With a moderate risk level of 3, the dam plays a crucial role in protecting the surrounding area from the impacts of flooding and water resource management.
As part of the Fort Worth District, the Tehuacana Creek WS SCS Site 23 Dam represents a key component of the region's water resource infrastructure. With a focus on flood risk reduction and a history of successful operation since its completion in 1963, this earth dam serves as a testament to the importance of proactive climate adaptation and water management strategies in safeguarding communities against the impacts of extreme weather events.

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.
