Summary

Built in 1979, this Earth dam stands at a height of 11 feet and stretches a length of 870 feet, providing a storage capacity of 105 acre-feet. Surrounded by the scenic TR-Chacon Creek, this dam plays a crucial role in regulating water flow and managing the drainage area in Webb County, Texas.

Despite its important role in water resource management, Minnie Martin Lake Dam has not been rated for its condition assessment, with a high risk potential identified. The dam lacks a spillway and has limited outlet gates, which poses challenges in case of emergencies. The regulatory oversight by the Texas Commission on Environmental Quality includes regular inspections, but there are no specific emergency action plans in place. Given its critical location and the risk factors identified, there is a need for enhanced risk management measures and updated emergency preparedness protocols to ensure the safety and stability of this vital water infrastructure in the region.

As water resource and climate enthusiasts monitor the developments surrounding Minnie Martin Lake Dam, there is a call for increased attention to its condition assessment, hazard potential, and emergency response protocols. With the potential risks associated with the dam's design and limited infrastructure, stakeholders must work together to mitigate any potential threats and ensure the long-term safety and sustainability of this essential water management structure in the heart of Webb County, Texas.

Dam Data Reference

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.
