Las Minas Ranch Dam No 1-59 dam
Las Minas Ranch Dam No 1-59
Las Minas Ranch Dam No 1-59, located in Webb County, Texas, was completed in 1959 under the supervision of the USDA NRCS. This private earth dam serves the primary purposes of fire protection, stock, or small fish pond. With a height of 20 feet and a length of 820 feet, the dam has a storage capacity of 158 acre-feet and covers a surface area of 12 acres.
Although the dam does not have a spillway, it is equipped with one outlet gate. While it has not been rated for condition assessment, the risk potential is considered high. Despite not being state regulated, the dam is subject to state permitting and inspection requirements. The structure plays a crucial role in water resource management in the region, contributing to the conservation and utilization of water resources for agricultural and ecological purposes.
Las Minas Ranch Dam No 1-59 stands as a testament to the collaborative efforts of the Natural Resources Conservation Service and the private owners in safeguarding water resources and ensuring the sustainability of the surrounding ecosystem. As a key component of the water infrastructure in the area, the dam serves as a vital resource for mitigating fire risks, supporting livestock operations, and maintaining a healthy aquatic habitat. Its strategic location along the TR-Rio Grande further underscores its significance in the region's water management and climate resilience efforts.
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.
- 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.
- 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.
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, environmental 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.

About Las Minas Ranch Dam No 1-59
Where does the data for Las Minas Ranch Dam No 1-59 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Not Available hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
