Summary
Completed in 1972, this earth dam stands at a height of 35 feet and stretches over 2570 feet, providing flood risk reduction and storing a maximum of 2434 acre-feet of water. Despite being designated as "Not Rated" in terms of condition assessment, its high hazard potential indicates the importance of regular inspections and maintenance to ensure its structural integrity.
This Local Government-owned dam serves multiple purposes including fire protection, stock watering, and small fish pond creation, in addition to flood risk reduction. It is regulated by the Texas Commission on Environmental Quality (TCEQ) and falls under the jurisdiction of the state. With a drainage area of 3.13 square miles and a surface area of 30 acres, the Tehuacana Creek WS SCS Site 1a Dam plays a crucial role in managing water resources in the region.
While lacking certain features like a spillway, the dam's impact on the surrounding area is significant, as reflected in its risk assessment rating of "High (2)". With Roger Williams as the Congressional representative for the area, stakeholders and water resource enthusiasts should monitor the dam's condition closely to ensure its continued effectiveness in flood risk reduction and water management along the Tehuacana Creek.

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.
