Dry Devils And Lowrey Ws Scs Site 12 Dam dam
Dry Devils And Lowrey Ws Scs Site 12 Dam
Located in Sonora, Texas, the Dry Devils and Lowrey WS SCS Site 12 Dam stands as a testament to flood risk reduction efforts in the area. Built in 1959 by the USDA NRCS, this earth dam spans 1475 feet in length and reaches a height of 37 feet, with a storage capacity of 2076 acre-feet. Designed for the primary purpose of flood risk reduction, this structure plays a crucial role in protecting the surrounding area from potential water-related hazards.
Managed by the TCEQ and subject to state regulation, the dam is inspected every five years to ensure its structural integrity. With a fair condition assessment as of April 2021, the dam has a moderate risk level assigned to it, indicating the need for ongoing monitoring and potential risk management measures. Equipped with one slide and two uncontrolled outlet gates, the dam is prepared to handle maximum discharges of 2076 cubic feet per second.
As an important piece of infrastructure in Sutton County, the Dry Devils and Lowrey WS SCS Site 12 Dam serves as a vital tool in safeguarding the community against flooding events. With its strategic location on TR-LOWREY DRAW and close proximity to the city of Sonora, this dam plays a critical role in mitigating water-related risks and ensuring the safety and well-being of local residents.
Dam data reference
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.
- 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.
- 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.
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, environmental 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.

About Dry Devils And Lowrey Ws Scs Site 12 Dam
Where does the data for Dry Devils And Lowrey Ws Scs Site 12 Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Not Available hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
