Summary
The dam stands at a height of 13 feet and has a length of 1142 feet, providing a storage capacity of 80 acre-feet. Situated on Leoncita Creek in McMullen County, Texas, this dam plays a crucial role in water resource management and wildlife conservation in the region.
Despite being privately owned, the dam is subject to state permitting and inspection, ensuring its structural integrity and compliance with regulations. The lack of a spillway and associated locks indicates a low risk of failure, although a risk assessment categorizes it as having a moderate hazard potential. The dam's strategic location and design make it a key infrastructure for maintaining water levels, supporting local ecosystems, and enhancing the overall resilience of the region in the face of climate change impacts.
For water resource and climate enthusiasts, Robert Wheeler Lake No 1 Dam serves as a fascinating example of sustainable water management and infrastructure development in a rural setting. Its incorporation of fire protection, stock watering, and recreational features highlights the versatility of such structures in addressing multiple community needs. As water scarcity and extreme weather events become more prevalent, the importance of well-maintained dams like Robert Wheeler Lake No 1 Dam in ensuring water security and environmental sustainability cannot be overstated.

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.
