Summary
Built in 1960 by the USDA NRCS, this earth dam stands at a height of 43 feet and spans a length of 1430 feet. With a storage capacity of 2187 acre-feet, it plays a vital role in managing floodwaters and protecting the surrounding area from potential inundation.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), this dam undergoes regular inspections to ensure its structural integrity and operational effectiveness. The dam features an uncontrolled spillway and outlet gates for water release, with a maximum discharge capacity of 10738 cubic feet per second. Despite being classified as having a moderate hazard potential, the dam's condition assessment in April 2021 deemed it satisfactory, highlighting its importance in mitigating flood risks and safeguarding the community of Sonora.
With its strategic location and design, Dry Devils and Lowrey WS SCS Site 6 Dam stands as a testament to the collaborative efforts of government agencies and engineering professionals in water resource management. As climate change continues to pose challenges to water infrastructure, this dam serves as a vital asset in protecting lives and properties from the impacts of extreme weather events, showcasing the importance of resilient infrastructure in building climate-resilient communities.

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.
