Leyendecker Lake Dam dam
Leyendecker Lake Dam
Leyendecker Lake Dam, located in Webb, Texas, is a private-owned structure completed in 1979 with a primary purpose of fire protection, stock, or small fish pond. The dam is an earth-type structure with a height of 8 feet and a length of 1100 feet, providing a storage capacity of 77 acre-feet. Situated on the TR-Becerra Creek, the dam serves as a vital resource for the surrounding area, ensuring water availability for various uses. Despite its age, the dam is currently assessed as being in a not rated condition with a high risk potential.
With no spillway and limited inspection data available, the condition of Leyendecker Lake Dam raises concerns for water resource and climate enthusiasts. The absence of emergency action plans and inundation maps, coupled with a lack of hazard potential assessment, highlights the need for improved risk management measures to safeguard the surrounding community in the event of a dam failure. The dam's location in the Galveston District adds to its significance as a water resource structure in the region, emphasizing the importance of regular inspections and maintenance to ensure its structural integrity and functionality.
As an earth-type dam with a critical risk rating, Leyendecker Lake Dam presents a complex challenge for water resource management in Texas. The dam's association with fire protection and small-scale water storage underscores its importance for local agricultural and emergency preparedness needs. However, the lack of detailed data on inspections, emergency response plans, and hazard assessments raises concerns about the dam's long-term sustainability and safety. Moving forward, improved monitoring and risk mitigation strategies are essential to address potential vulnerabilities and ensure the continued reliability of Leyendecker Lake Dam as a vital water resource in the region.

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 Leyendecker Lake Dam
Where does the data for Leyendecker Lake Dam 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.
