Summary
Built in 1973 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock, and small fish pond. With a height of 18 feet and a length of 1140 feet, the dam has a storage capacity of 240 acre-feet and covers a surface area of 8 acres.
Although not regulated by the state, Tom Ranch Lake No 2 Dam is designed to withstand high-risk situations with a hazard potential of "Not Available" and a risk assessment rating of "High (2)". Despite the lack of a spillway, the dam is equipped with one outlet gate and is not associated with any locks. While the condition assessment remains unrated, the dam is inspected periodically to ensure its structural integrity and compliance with safety standards.
Located along the TR-Atascosa River and under the jurisdiction of the Galveston District, Tom Ranch Lake No 2 Dam stands as a vital resource for water management and climate resilience in the region. As an essential component of the local ecosystem, this dam plays a crucial role in mitigating flood risks, providing water for agricultural and recreational purposes, and supporting the overall sustainability of the surrounding area.

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.
