Sister Grove Creek Ws Scs Site 33 Dam dam
Sister Grove Creek Ws Scs Site 33 Dam
Sister Grove Creek WS SCS Site 33 Dam, located in Grayson County, Texas, is a significant Earth dam built in 1957 by the USDA NRCS for flood risk reduction along the East Prong Sister Grove Creek. With a height of 37 feet and a length of 965 feet, this dam serves a primary purpose of flood risk reduction, storing up to 428 acre-feet of water. Despite not having a spillway, the dam provides essential protection to the surrounding area, with a high hazard potential rating.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the Sister Grove Creek WS SCS Site 33 Dam remains under state jurisdiction for permitting, inspection, and enforcement. Although the dam's condition assessment is not rated, it is crucial to monitor its structural integrity due to its high risk assessment rating of 2. With no designated emergency action plan (EAP) or updated inundation maps, stakeholders must prioritize risk management measures and ensure that emergency contacts are up to date to address any potential hazards effectively.
For water resource and climate enthusiasts, the Sister Grove Creek WS SCS Site 33 Dam presents an intriguing case study in dam engineering and management. As a key flood risk reduction structure in the area, understanding its design, storage capacity, and risk assessment can provide valuable insights into the challenges and opportunities of managing water resources in a changing climate. With a focus on enhancing safety measures and risk mitigation strategies, stakeholders can work towards ensuring the long-term sustainability and resilience 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.

About Sister Grove Creek Ws Scs Site 33 Dam
Where does the data for Sister Grove Creek Ws Scs Site 33 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.
