Macho Arroyo Ws Scs Site 1 Dam Reservoir Report

Last Updated: March 13, 2026

Macho Arroyo WS SCS Site 1 Dam, located in Esperanza, Hudspeth County, Texas, is a key structure designed by the USDA NRCS to provide flood risk reduction for the region.


Summary

Completed in 1962, this earth dam stands at a height of 50 feet and spans a length of 2850 feet, with a maximum storage capacity of 2477 acre-feet. Its primary purpose includes flood risk reduction, irrigation, and recreation, along with supporting fish and wildlife habitats.

The dam, situated on the Macho Arroyo stream, is regulated by the TCEQ and undergoes regular inspections to ensure its structural integrity and safety. With uncontrolled and valve outlet gates, as well as a spillway width of 303 feet, the dam is equipped to manage a maximum discharge of 7766 cubic feet per second. Despite being assessed as in fair condition as of October 2015, the dam's hazard potential and emergency preparedness status are not currently available.

Overall, Macho Arroyo WS SCS Site 1 Dam plays a crucial role in managing water resources in the region, providing essential flood protection and supporting various recreational and environmental activities. As a part of the local government's infrastructure, this dam demonstrates a commitment to sustainable water management practices and serves as a vital asset for the community's resilience to climate-related challenges.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
