Sister Grove Creek Ws Scs Site 36 Dam dam
Sister Grove Creek Ws Scs Site 36 Dam
Sister Grove Creek WS SCS Site 36 Dam, located in Grayson County, Texas, is a vital structure designed by the USDA NRCS in 1960 for flood risk reduction along the TR-East Prong Sister Grove Creek. This earth dam, standing at 21 feet in height and spanning 750 feet in length, serves to protect the surrounding area from potential flooding events. With a storage capacity of 218 acre-feet and a drainage area of 0.44 square miles, the dam plays a crucial role in managing water flow and minimizing the risk of inundation.
Despite being classified as having a fair condition assessment, the dam has a moderate risk level of 3, as per the latest data available. It is regulated by the Texas Commission on Environmental Quality (TCEQ) and undergoes regular inspections to ensure its structural integrity and functionality. The dam features an uncontrolled spillway with a width of 52 feet and two uncontrolled outlet gates. While the hazard potential is not available, the dam's risk management measures and emergency action plan (EAP) status remain unspecified, highlighting areas for further improvement and monitoring in the future.
For water resource and climate enthusiasts, Sister Grove Creek WS SCS Site 36 Dam presents an intriguing case study in flood risk reduction infrastructure. Its role in safeguarding the local community and environment against potential flooding events underscores the importance of effective dam management and maintenance practices. With a focus on continuous monitoring and improvement, this dam serves as a crucial asset in enhancing water resource resilience and climate adaptation efforts in the region.
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 36 Dam
Where does the data for Sister Grove Creek Ws Scs Site 36 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.
