Lower Brushy Creek Ws Scs Site 21 Dam dam
Lower Brushy Creek Ws Scs Site 21 Dam
Lower Brushy Creek WS SCS Site 21 Dam, located in Williamson County, Texas, was completed in 1960 with a primary purpose of flood risk reduction. Designed by USDA NRCS, this earth dam stands at a height of 19 feet and spans a length of 1200 feet along the Brushy Creek. The dam has a storage capacity of 548 acre-feet, with a normal storage level of 54 acre-feet.
This dam is regulated by the Texas Commission on Environmental Quality (TCEQ) and is inspected, permitted, and enforced by state agencies. The condition of the dam is assessed as fair, with a high risk level of 2. Although the hazard potential is not available, the dam is categorized as having a high risk due to its critical function in flood risk reduction. With no spillway and limited structural features, the dam serves as a vital component in managing water resources and protecting the surrounding areas from potential flooding events.
Owned by the local government, Lower Brushy Creek WS SCS Site 21 Dam plays a crucial role in fire protection, stock, and small fish ponds in addition to its core function of flood risk reduction. With its strategic location in Williamson County and its historical significance dating back to 1960, this dam stands as a testament to the importance of water resource management in the face of changing climate patterns and increasing risks of extreme weather events.
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 21 Dam
Where does the data for Lower Brushy Creek Ws Scs Site 21 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.
