Diablo Reservoir Levee Reservoir Report
Last Updated: March 13, 2026
The Diablo Reservoir Levee in Texas was completed in 1993 and serves the primary purpose of irrigation along the Rio Grande.
Summary
This earth dam, with a height of 16 feet and a length of 12,850 feet, has a storage capacity of 40,200 acre-feet and is regulated by the Texas Commission on Environmental Quality. Despite being rated as having a high risk potential, the condition of the structure has not been assessed.
Owned by the local government, the Diablo Reservoir Levee was designed by Kirby Engineering Inc and is situated in Hudspeth County, Texas. With two Tainter radial gates as outlet gates, the dam has not been equipped with a spillway and does not have any associated structures. While the structure is not currently rated for condition assessment, it is regularly inspected, permitted, and enforced by the state regulatory agency.
Located in an area with a high risk assessment for potential hazards, the Diablo Reservoir Levee plays a crucial role in providing irrigation water for the surrounding area. Despite lacking certain safety features such as spillways, the dam continues to be maintained and inspected to ensure its integrity and functionality for water resource management in the region.

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.
