Lamesa Ranch Dam No 1-63 dam
Lamesa Ranch Dam No 1-63
Lamesa Ranch Dam No 1-63, located in Zapata, Texas, is a privately owned earth dam designed by the USDA NRCS in 1963. With a primary purpose of fire protection, stock, or small fish pond, the dam stands at a height of 10 feet and stretches 800 feet in length. It has a storage capacity of 94 acre-feet and covers a surface area of 23.5 acres, serving as a vital resource for water conservation in the region.
Although the dam does not have a spillway, it is equipped with one outlet gate for water release. The risk assessment for Lamesa Ranch Dam No 1-63 indicates a high hazard potential, emphasizing the importance of regular inspections and maintenance. While the dam's condition assessment is currently not rated, its strategic location on the TR-Rio Grande river makes it a key structure for water management and climate resilience efforts in the area.
As part of the Galveston District, the dam plays a crucial role in water resource management, providing essential support for agricultural activities and wildlife habitats. With its historical significance and continued relevance in the present day, Lamesa Ranch Dam No 1-63 serves as a testament to the importance of sustainable water infrastructure for the community and the environment.
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 Lamesa Ranch Dam No 1-63
Where does the data for Lamesa Ranch Dam No 1-63 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.
