Summary
Constructed in 1959 by the USDA NRCS, this earth dam spans 1420 feet with a height of 48 feet, providing essential protection to the surrounding area from potential flooding events. With a maximum storage capacity of 4020 acre-feet and a normal storage of 103 acre-feet, this dam plays a crucial role in managing water resources in the region.
The dam's primary purpose is flood risk reduction, serving as a critical infrastructure for safeguarding communities and properties along the TR-LOWREY DRAW stream. Operated by the local government, the dam is regulated by the TCEQ and undergoes regular inspections to ensure its structural integrity and functionality. Despite its fair condition assessment in 2021, the dam continues to play a vital role in water resource management and climate resilience efforts in Sutton County, Texas.
With a moderate risk assessment rating, the Dry Devils and Lowrey WS SCS Site 10 Dam remains a key feature in the region's flood control and water management strategies. Equipped with uncontrolled and valve outlet gates, this dam is prepared to handle potential flood events and discharge excess water safely. As climate change continues to impact the frequency and intensity of extreme weather events, infrastructure like this dam will be crucial in mitigating risks and protecting communities in Sutton County.

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.
