Frd No 21 dam
Frd No 21
Located in Winfield, Kansas, Frd No 21, also known as Timber Creek Watershed Dam No 21, is a crucial structure designed by the USDA NRCS for flood risk reduction. Built in 1975, this earth dam stands at 39.7 feet high with a hydraulic height of 42 feet and a structural height of 48 feet. Its primary purpose is flood risk reduction, serving the Richland Creek area with a normal storage capacity of 294 acre-feet and a maximum discharge of 4092 cubic feet per second.
The dam covers a drainage area of 6.96 square miles and has a storage capacity of 3882 acre-feet. With a surface area of 54 acres and a length of 2438 feet, Frd No 21 plays a vital role in managing water resources in Cowley County, Kansas. Despite being assessed as in fair condition with a high hazard potential, the dam is regularly inspected by the Kansas Department of Agriculture to ensure its structural integrity and public safety.
In the event of emergencies, the dam has a hazard potential rating of 3, indicating a moderate risk level. With its uncontrolled spillway type and a spillway width of 80 feet, Frd No 21 is a critical infrastructure for flood control in the region. Its location in the Timber Creek Watershed highlights its significance in safeguarding the local community and environment from the impacts of extreme weather events and flooding.

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 Frd No 21
Where does the data for Frd No 21 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 High 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.
