Summary
This earth dam, completed in 1964, boasts a height of 16 feet and a length of 1625 feet, providing a storage capacity of 960 acre-feet. Situated on Horse Creek and under the jurisdiction of the Texas Commission on Environmental Quality (TCEQ), this dam plays a crucial role in the local water resource management system.
With a high hazard potential rating, the dam requires close monitoring and management to ensure public safety and environmental sustainability. Despite being rated as not available for condition assessment, the dam's risk level is categorized as high. The absence of a spillway and limited discharge capacity adds to the complexity of managing potential flood risks in the area, highlighting the importance of regular inspections and risk mitigation measures.
For water resource and climate enthusiasts, Triple S Lake No 2 Dam serves as a focal point for understanding the intricate balance between water supply, recreation, and environmental safety. As a privately owned structure, its significance in the region's water management efforts underscores the need for proactive measures to address potential hazards and ensure the long-term resilience of the surrounding ecosystem.

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.
