Summary

Built in 1963 by the USDA NRCS, this earth dam stands at a height of 24 feet and has a length of 1960 feet, providing a maximum storage capacity of 1179 acre-feet. With a normal storage capacity of 135 acre-feet and a drainage area of 1.95 square miles, this dam plays a crucial role in protecting the surrounding area from potential flooding events.

The dam features an uncontrolled spillway with a width of 208 feet and is equipped with slide and uncontrolled outlet gates. The inspection frequency for this structure is every 5 years, with the last inspection conducted in November 2015. While the hazard potential and condition assessment are not available, the risk assessment for this dam is moderate (3). With state regulation, permitting, inspection, and enforcement in place, the Tehuacana Creek WS SCS Site 22 Dam ensures the safety and security of the local community and ecosystem.

As a key component of the Fort Worth District, this dam serves multiple purposes including fire protection, stock, or small fish pond, in addition to flood risk reduction. With its strategic location and design, the Tehuacana Creek WS SCS Site 22 Dam is an essential infrastructure that underscores the importance of water resource management and climate resilience in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
