About this dam

Big Sandy Creek Ws Scs Site 24a Dam

Located in Wise, Texas, the Big Sandy Creek WS SCS Site 24a Dam is a crucial structure designed by the USDA NRCS to mitigate flood risks along the TR-Grapevine Creek. Completed in 1988, this earth dam stands at a height of 44 feet and spans a length of 1463 feet, providing a storage capacity of 703 acre-feet for floodwaters. With a normal storage capacity of 284 acre-feet and a drainage area of 634 square miles, this dam plays a vital role in managing water flow and protecting the surrounding area from potential flooding events.

Managed by local government authorities and regulated by the Texas Commission on Environmental Quality (TCEQ), the Big Sandy Creek WS SCS Site 24a Dam is inspected and maintained to ensure its effectiveness in flood risk reduction. The dam features uncontrolled spillways and outlet gates for water release, with a maximum discharge capability of 786 cubic feet per second. Despite its moderate risk assessment rating, the dam's condition remains unrated, highlighting the need for ongoing monitoring and potential risk management measures.

As an essential infrastructure for water resource management in the region, the Big Sandy Creek WS SCS Site 24a Dam serves as a critical component in the overall flood control system. With its strategic location and design features, this dam plays a pivotal role in safeguarding communities and infrastructure from the impacts of extreme weather events, showcasing the importance of sustainable water resource and climate resilience practices in the face of changing environmental conditions.

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 Big Sandy Creek Ws Scs Site 24a Dam

Where does the data for Big Sandy Creek Ws Scs Site 24a 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.
