Grays Creek Ws Scs Site 7b Dam dam
Grays Creek Ws Scs Site 7b Dam
Grays Creek WS SCS Site 7b Dam, located in Navarro County, Texas, is a vital structure designed by the USDA NRCS in 1955 for flood risk reduction along Hackberry Creek. This Earth-type dam stands at a height of 28 feet and spans a length of 2890 feet, with a storage capacity of 2125 acre-feet and a drainage area of 3.06 square miles. Despite its age, the dam has not been inspected or rated for condition, but its hazard potential is currently classified as "Not Available" with a high risk assessment rating of 2.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the Grays Creek WS SCS Site 7b Dam serves as a crucial infrastructure for flood control in the region. With no spillway and limited emergency preparedness information available, the dam's risk management measures and emergency response protocols are currently not well-documented. Despite these challenges, the dam continues to play a significant role in safeguarding the surrounding areas from potentially devastating flood events.
As water resource and climate enthusiasts, the Grays Creek WS SCS Site 7b Dam presents a fascinating case study in dam infrastructure and risk assessment. Its historical significance, engineering design, and current risk management practices offer valuable insights into the complexities of managing water resources in a changing climate. With ongoing monitoring and potential improvements in emergency response planning, this dam stands as a critical piece of infrastructure in protecting communities and ecosystems from the impacts 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 Grays Creek Ws Scs Site 7b Dam
Where does the data for Grays Creek Ws Scs Site 7b 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.
