Plum Creek Ws Scs Site 21 Dam dam
Plum Creek Ws Scs Site 21 Dam
Plum Creek WS SCS Site 21 Dam, located in Caldwell, Texas, was completed in 1962 with a primary purpose of flood risk reduction along Dry Creek. This earth dam, designed by USDA NRCS, stands at a height of 41 feet and spans 3400 feet, providing a maximum storage capacity of 5318 acre-feet. The dam's fair condition assessment in 2015 and moderate risk assessment highlight its importance in protecting the surrounding area from potential flooding events.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), Plum Creek WS SCS Site 21 Dam is equipped with an uncontrolled spillway and multiple outlet gates for water release. With a drainage area of 8.65 square miles and a surface area of 56.95 acres, the dam plays a crucial role in managing water flow and minimizing flood risks in the region. Despite its age, the dam continues to undergo regular inspections and maintenance to ensure its continued effectiveness in flood risk reduction.
In the event of an emergency, the dam's emergency action plan (EAP) status and risk management measures are not specified, indicating a potential area for improvement. However, with its significant storage capacity and design features, Plum Creek WS SCS Site 21 Dam remains a vital infrastructure asset for the community, providing essential protection against flooding and safeguarding water resources in the area.
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 21 Dam
Where does the data for Plum Creek Ws Scs Site 21 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.
