Calaveras Creek Ws Scs Site 9 Dam dam
Calaveras Creek Ws Scs Site 9 Dam
The Calaveras Creek WS SCS Site 9 Dam, located in Bexar County, Texas, serves as a vital structure for flood risk reduction along the TR-CHUPADERAS CREEK. Built in 1955 by USDA NRCS, this earth dam stands at a height of 28 feet and stretches 1176 feet in length. With a storage capacity of 907 acre-feet and a normal storage of 107 acre-feet, the dam plays a crucial role in managing water flow and protecting the surrounding areas from flooding.
Managed by the TCEQ and designated as a state-regulated structure, the Calaveras Creek WS SCS Site 9 Dam has a spillway width of 203 feet and features outlet gates including a slide gate and two uncontrolled gates. Despite being rated as ‘Not Available’ in terms of hazard potential and condition assessment, the dam undergoes inspections every 5 years to ensure its structural integrity. With a moderate risk assessment level of 3, the dam is a key component in the region’s water resource management and climate resilience efforts.
As a part of the flood risk reduction infrastructure, the Calaveras Creek WS SCS Site 9 Dam contributes to the overall water management strategy in Bexar County, Texas. With its strategic location and design, this dam serves as a crucial barrier against potential flooding events, safeguarding the local community and environment. As climate change continues to impact water resources, the importance of structures like the Calaveras Creek WS SCS Site 9 Dam in ensuring water security and resilience cannot be overstated.

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 Calaveras Creek Ws Scs Site 9 Dam
Where does the data for Calaveras Creek Ws Scs Site 9 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.
