Summary
Despite being non-federally regulated, the dam is subject to state permitting and inspection requirements. The structure is associated with the TR-San Lorenzo Creek and is managed by the Fort Worth District of the US Army Corps of Engineers.
With a surface area of 24 acres, East Losa 2 Tank Dam plays a crucial role in water resource management in the region. Although the dam does not have a spillway, it is equipped with a single outlet gate. The risk assessment for the dam indicates a high risk level and its condition is currently not rated. While the structure has not been modified in recent years, the potential hazard posed by the dam underscores the importance of regular inspections and maintenance to ensure public safety and water resource sustainability.
As a point of interest for water resource and climate enthusiasts, East Losa 2 Tank Dam serves as a significant infrastructure for water storage and management in Webb County, Texas. The dam's location on the TR-San Lorenzo Creek highlights its contribution to the local watershed and ecosystem. The data on the dam's design, construction, and regulatory oversight provide valuable insights into the complexities of managing water resources in a changing climate.

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.
