Plum Creek Ws Scs Site 20 Dam dam
Plum Creek Ws Scs Site 20 Dam
Plum Creek WS SCS Site 20 Dam, located in Caldwell, Texas, is a significant earth dam designed by the USDA NRCS in 1965 for flood risk reduction along the Rabbit Branch river. Standing at a height of 38 feet and with a length of 2160 feet, this dam has a storage capacity of 1178 acre-feet and serves a drainage area of 1.95 square miles. With a maximum discharge capacity of 6134 cubic feet per second and an uncontrolled spillway width of 120 feet, this dam plays a crucial role in managing water flow in the region.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), Plum Creek WS SCS Site 20 Dam has not been rated for its condition but is considered to have a moderate risk level. The dam features uncontrolled outlet gates and a buttress core type, serving its primary purpose of flood risk reduction effectively. Despite not having specific emergency action plans or inundation maps prepared, this dam remains a key infrastructure piece in the area's water resource management efforts, ensuring the safety and well-being of the surrounding communities.
As a part of the Galveston District and owned by the Natural Resources Conservation Service, Plum Creek WS SCS Site 20 Dam represents a vital component of the regional water infrastructure. Its strategic location and design contribute to the overall resilience against flooding events, highlighting the importance of sustainable water resource management in the face of changing climate patterns. With a rich history of service since its completion in the 1960s, this dam stands as a testament to the ongoing efforts to protect and preserve water resources in Texas.
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 Plum Creek Ws Scs Site 20 Dam
Where does the data for Plum Creek Ws Scs Site 20 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.
