Summary

Standing at a height of 75 feet with a length of 3100 feet, the dam has a storage capacity of 19,024 acre-feet and a maximum discharge rate of 83,172 cubic feet per second. The dam's spillway, with a width of 438 feet, is uncontrolled, and it is equipped with slide and uncontrolled outlet gates.

Managed by the Texas Commission on Environmental Quality (TCEQ), the dam is in satisfactory condition according to the latest assessment in April 2021. The risk assessment for the dam is moderate, with no specific hazard potential listed. The dam's emergency action plan (EAP) status and readiness for various scenarios are not provided in the data, but the agency responsible for its operations and inspections is the Natural Resources Conservation Service. Overall, the Comal River WS SCS Site 2 Dam plays a crucial role in flood control and water resource management in the area, ensuring the safety of nearby communities during times of high water flow.

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.
