Summary

Completed in 1975, this earth dam stands at a height of 71.1 feet and has a structural height of 83 feet, providing a storage capacity of 8,675 acre-feet. With a drainage area of 11.55 square miles, the dam serves as a vital flood risk reduction measure for the city of San Antonio.

The dam features an uncontrolled spillway with a width of 203 feet, allowing for a maximum discharge of 28,319 cubic feet per second in times of heavy rainfall. The outlet gates include a slide (sluice gate) and two uncontrolled gates, ensuring proper water flow management during flood events. The dam is state-regulated by the Texas Commission on Environmental Quality (TCEQ), with regular inspections conducted to ensure its structural integrity and safety.

Despite its moderate risk assessment level, the Salado Creek WS SCS Site 1 Dam plays a crucial role in protecting the surrounding area from flooding. With its strategic location and design features, this dam serves as a testament to effective water resource management and climate resilience efforts 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.
