Lower Brushy Creek Ws Scs Site 18 Dam dam
Lower Brushy Creek Ws Scs Site 18 Dam
The Lower Brushy Creek WS SCS Site 18 Dam, located in Williamson County, Texas, was completed in 1963 by the USDA NRCS and serves as a vital structure for flood risk reduction along the Long Branch river stream. The dam, primarily constructed of earth with a buttress core type, stands at a height of 34 feet and spans a length of 3240 feet. With a storage capacity of 2790 acre-feet, the dam plays a crucial role in managing water flow and maintaining normal storage levels to mitigate flood risks in the area.
This dam also serves multiple purposes including fire protection, stock or small fish pond maintenance, and flood risk reduction activities. It is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure its structural integrity. The dam features an uncontrolled spillway with a width of 302 feet and outlet gates for water release. Despite being assessed as in fair condition, the dam poses a moderate risk level (3) according to the risk assessment, highlighting the importance of ongoing maintenance and monitoring efforts to ensure its continued effectiveness in flood mitigation and water resource management.
With its critical role in flood risk reduction and water management, the Lower Brushy Creek WS SCS Site 18 Dam stands as a testament to the importance of infrastructure in ensuring the safety and well-being of communities in the face of climate challenges. As climate change continues to impact water resources, the proper maintenance and operation of dams like this one are essential in safeguarding against potential flooding and ensuring sustainable water management practices for future generations.
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 Lower Brushy Creek Ws Scs Site 18 Dam
Where does the data for Lower Brushy Creek Ws Scs Site 18 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.
