About this dam

Upper Brushy Creek Ws Scs Site 12 Dam

The Upper Brushy Creek WS SCS Site 12 Dam, located in Round Rock, Texas, is a critical flood risk reduction structure designed by the USDA NRCS and completed in 1967. This earth dam stands at a height of 32 feet and spans a length of 5000 feet, with a storage capacity of 2984 acre-feet and a drainage area of 3.57 square miles. The dam serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction along the Onion Branch river.

Managed by the Texas Commission on Environmental Quality (TCEQ), the dam has undergone inspections with a satisfactory condition assessment as of June 2017. The dam features an uncontrolled spillway with a width of 302 feet and outlet gates including a slide gate and two uncontrolled gates. Despite a moderate risk assessment level, the dam has not been assigned a hazard potential.

With its strategic location and effective design, the Upper Brushy Creek WS SCS Site 12 Dam plays a crucial role in protecting the surrounding community from potential flooding events. Water resource and climate enthusiasts will appreciate the engineering ingenuity and regulatory oversight that have gone into ensuring the safety and functionality of this essential infrastructure.

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.

FAQ

About Upper Brushy Creek Ws Scs Site 12 Dam

Where does the data for Upper Brushy Creek 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.
