Summary
Completed in 1960, this earth dam stands at a height of 35 feet and has a length of 2000 feet, providing essential flood risk reduction for the area. With a normal storage capacity of 197 acre-feet and a maximum discharge of 12,563 cubic feet per second, the dam plays a crucial role in protecting the surrounding community from potential flooding events.
Managed by local government authorities and regulated by the Texas Commission on Environmental Quality (TCEQ), Dry Devils and Lowrey WS SCS Site 7 Dam has been assessed to be in fair condition as of April 2021. The dam boasts an uncontrolled spillway with a width of 183 feet and features two uncontrolled outlets and one valve outlet for water management. While the hazard potential is noted as not available, the risk assessment for the dam is moderate (level 3), indicating the importance of ongoing monitoring and maintenance to ensure its continued effectiveness in flood risk reduction.
With a drainage area of 11.1 square miles and a storage capacity of 5,560 acre-feet, Dry Devils and Lowrey WS SCS Site 7 Dam serves as a crucial infrastructure for water resource management in the region. As climate change continues to impact weather patterns, structures like this dam are essential for mitigating flood risks and protecting communities from potential disasters.

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.
