Summary
Constructed in 1976 by the USDA NRCS, this earth dam reaches a height of 42 feet, with a total structural height of 69 feet and a length of 1690 feet. It provides a maximum storage capacity of 3053 acre-feet to mitigate flooding in the area, with a normal storage level of 128 acre-feet and a drainage area of 2.99 square miles.
The dam features various outlet gates including Other Controlled, Slide (sluice gate), and Uncontrolled types, ensuring effective water management during peak discharge events of up to 30,102 cubic feet per second. The dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular state inspections to ensure its safety and functionality. Despite its importance in flood risk reduction, the hazard potential and condition assessment of the dam are currently not available, highlighting the need for ongoing monitoring and maintenance to safeguard the surrounding community.
With its strategic location and significant impact on the local hydrology, Salado Creek WS SCS Site 13a Dam plays a crucial role in water resource management in Bexar County, Texas. As climate change continues to influence precipitation patterns and increase the frequency of extreme weather events, the effectiveness and integrity of this dam are essential for protecting downstream areas from potential flooding. Ongoing efforts by regulatory agencies and the dam's primary owner, the local government, are paramount in ensuring the continued safety and functionality of this critical infrastructure for years to come.

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.
