Summary
Completed in 1941, this private-owned earth dam stands at a height of 8 feet and spans a length of 2154 feet, with a storage capacity of 544 acre-feet. Despite its modest size, the dam plays a crucial role in water supply for the surrounding area.
Managed by the Texas Commission on Environmental Quality (TCEQ), the La Mata Lake Dam is regulated, inspected, and enforced by the state, ensuring its safety and functionality. Its hazard potential is categorized as not available, with a high risk assessment rating. While the dam lacks a spillway, its outlet gates provide controlled water release. With its rich history and continued importance in providing water resources, the La Mata Lake Dam stands as a testament to responsible water management in the region.
Enthusiasts of water resources and climate will appreciate the significance of the La Mata Lake Dam in maintaining water supply and supporting local ecosystems. As a key structure in the area, this dam serves as a reminder of the importance of sustainable water management practices and the crucial role that such infrastructure plays in protecting communities from potential hazards. Despite its small size, the La Mata Lake Dam stands as a symbol of resilience and innovation in water resource management in the heart of Texas.

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.
