Summary
6-73, located in Webb County, Texas, is a privately owned dam constructed in 1973 by the USDA NRCS for the primary purposes of fire protection, stock, and small fish pond. This earth dam, with a height of 12 feet and a length of 1020 feet, has a storage capacity of 64 acre-feet and covers a surface area of 11 acres. The dam is situated on the Tr- Nueces River within the Galveston District and is regulated by the Natural Resources Conservation Service.
Despite being classified as having a low hazard potential, Vergara Ranch No. 6-73 poses a moderate risk due to its condition assessment being unavailable. The dam has an uncontrolled spillway with a width of 100 feet and an outlet gate system. While the last inspection date and frequency are not provided, the dam's risk assessment suggests that there is room for improvement in its risk management measures to ensure its safety and functionality in the face of potential emergencies.
Overall, Vergara Ranch No. 6-73 serves as a vital infrastructure for water resource management in the area, providing essential services such as fire protection and stock water supply. With proper maintenance and monitoring, this dam can continue to support the needs of the community while safeguarding against any potential risks associated with its operation.

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.
