Lomaland Basin Dam Reservoir Report
Last Updated: March 10, 2026
Lomaland Basin Dam, located in El Paso, Texas, stands as a crucial infrastructure for flood risk reduction along the Jesuit Draw.
Summary
Completed in 2004, this earth-type dam stands at a height of 27 feet and spans 3,840 feet in length, with a storage capacity of 439 acre-feet. The dam's uncontrolled spillway, with a width of 1,050 feet, allows for a maximum discharge of 73,900 cubic feet per second, serving as a vital mechanism for managing excess water flow during heavy rainfall events.
Owned and regulated by the local government and overseen by the Texas Commission on Environmental Quality (TCEQ), Lomaland Basin Dam is subject to regular inspections to ensure its structural integrity and functionality. With a fair condition assessment as of April 2021, the dam continues to serve its primary purpose of flood risk reduction effectively. The surrounding community benefits from the dam's presence, providing a sense of security during times of heightened flood risks. The moderate risk assessment indicates the importance of ongoing maintenance and monitoring to safeguard against potential hazards and ensure the dam's continued reliability in protecting downstream areas.

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.
