Diablo Arroyo Ws Scs Site 1 Dam Reservoir Report
Last Updated: March 13, 2026
Located in Hudspeth, Texas, the Diablo Arroyo WS SCS Site 1 Dam is a vital structure designed by the USDA NRCS to serve flood risk reduction and irrigation purposes.
Summary
Completed in 1960, this earth dam stands at a height of 68 feet and stretches 1400 feet in length, with a storage capacity of 9000 acre-feet. The dam is situated on the Diablo Arroyo river and is regulated by the Texas Commission on Environmental Quality, ensuring proper inspection, permitting, and enforcement measures are in place to maintain its functionality.
With a moderate risk assessment rating, the Diablo Arroyo WS SCS Site 1 Dam is deemed to have fair condition as of the last assessment in December 2015. The dam features an uncontrolled spillway with a width of 93 feet and is equipped with two uncontrolled outlets and one valve. While the hazard potential is not available, the dam poses a manageable risk to the surrounding area. Despite its age, the dam continues to play a crucial role in managing water resources and reducing flood risks in the region, highlighting the importance of sustainable infrastructure for water resource and climate enthusiasts to monitor and support.

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.
