Summary
Completed in 1964, this earth dam stands at a height of 38 feet and has a length of 4455 feet, with a maximum storage capacity of 3416 acre-feet. The dam is regulated by the TCEQ and undergoes regular inspections to ensure its structural integrity.
With a primary purpose of flood risk reduction, the Upper Las Moras Creek Dam plays a vital role in protecting the surrounding Kinney County community from potential water-related disasters. The dam features an uncontrolled spillway, five uncontrolled outlet gates, and a drainage area of 6.7 square miles. In addition to its functional aspects, the dam also provides a surface area of 35 acres and a normal storage capacity of 171 acre-feet, contributing to the overall water management efforts in the region.
Despite its age, the Upper Las Moras Creek WS SCS Site 1 Dam is reported to be in satisfactory condition as of its most recent assessment in January 2018. Its moderate risk level is actively managed through regular inspections and maintenance protocols. This dam serves as a testament to the importance of strategic water resource management and climate adaptation strategies in safeguarding communities against the impacts of extreme weather events.

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.
