Summary
1-80 is a privately owned earth dam located in Webb County, Texas, along the Tr-Nueces River. Built in 1980 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock, and small fish pond management. With a height of 11 feet and a length of 1000 feet, this structure has a storage capacity of 51 acre-feet, providing valuable water resources for the surrounding area.
The dam has a low hazard potential and a moderate risk assessment rating, making it a crucial asset for water resource management in the region. It features an uncontrolled spillway with a width of 130 feet and an outlet gate for controlled water release. While the condition assessment is not available, the structure's design and construction by the Natural Resources Conservation Service ensure its reliability for water storage and flood protection.
Water resource and climate enthusiasts will appreciate the significance of Shipp Ranch No. 1-80 in safeguarding water sources and supporting ecosystem sustainability along the Tr-Nueces River. As a key infrastructure for fire protection and livestock needs, this earth dam showcases the importance of strategic water management in arid regions like Webb County, Texas. Its construction and maintenance by the USDA NRCS reflect a commitment to enhancing water resilience and environmental stewardship in the 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.
