Summary
The dam stands at a height of 18 feet and has a length of 1410 feet, with a storage capacity of 576 acre-feet. Situated on the TR-Nueces River, the dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections, permitting, and enforcement to ensure its safety and compliance with state regulations.
Despite being rated as having a high risk potential, the dam's condition assessment is currently not available. It does not have a spillway and is equipped with one outlet gate. The dam has not been modified in recent years, and its hazard potential and emergency preparedness status remain uncertain. With its location in La Salle County, the dam serves as a critical water resource for the region, highlighting the importance of monitoring and maintaining its structural integrity to mitigate any potential risks associated with its operation.
Overall, Martin Lake No 1 Dam serves as a vital infrastructure for water supply in the area, underscored by its historical significance and role in maintaining water security for surrounding communities. As water resource and climate enthusiasts, it is crucial to stay informed about the condition and management measures of dams like Martin Lake No 1 to ensure the sustainability and resilience of water infrastructure in the face of changing environmental conditions and increasing demand for water resources.

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.
