Sister Grove Creek Ws Scs Site 32 Dam dam
Sister Grove Creek Ws Scs Site 32 Dam
Sister Grove Creek WS SCS Site 32 Dam, located in Grayson County, Texas, stands as a testament to effective flood risk reduction measures implemented by the USDA NRCS in 1959. This earth dam with a height of 25 feet and a length of 1292 feet plays a crucial role in controlling the flow of the East Prong Sister Grove Creek during heavy rainfall events. With a storage capacity of 1406 acre-feet and a drainage area of 3.55 square miles, the dam helps mitigate flooding and ensures the safety of the surrounding communities.
The dam features an uncontrolled spillway with a width of 102 feet and two uncontrolled outlet gates. Despite being classified as having a fair condition assessment as of April 2021, the dam poses a moderate risk level due to its age and potential hazards. Regular inspections and maintenance efforts are essential to ensure the continued effectiveness and safety of the dam. As a state-regulated structure under the jurisdiction of TCEQ, the dam is subject to permitting, inspection, and enforcement measures to uphold its functionality and protect the environment.
As water resource and climate enthusiasts marvel at the engineering marvel that is Sister Grove Creek WS SCS Site 32 Dam, they can appreciate its role in safeguarding communities from flooding events. The structured management of the dam, including its emergency action plan and risk assessment, underscores the commitment to public safety and environmental stewardship. With a rich history of flood risk reduction and water management, this dam serves as a vital infrastructure piece in the region's water resource management efforts.
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 Sister Grove Creek Ws Scs Site 32 Dam
Where does the data for Sister Grove Creek Ws Scs Site 32 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.
