Frd No 21 dam
Frd No 21
Frd No 21, also known as Rock Creek Watershed Dam 21, is a local government-owned earth dam located in Butler County, Kansas. Built in 1966 by the USDA NRCS, this dam serves as a crucial structure for flood risk reduction in the Rock Creek-TR watershed. With a dam height of 34 feet and a storage capacity of 481.4 acre-feet, Frd No 21 plays a key role in protecting the surrounding area from potential flooding events.
Managed by the Kansas Department of Agriculture, Frd No 21 is regulated, permitted, inspected, and enforced by the state to ensure its structural integrity and overall safety. The dam, with a spillway width of 40 feet and an uncontrolled spillway type, has a low hazard potential and is currently rated as not assessed in terms of condition. Despite its moderate risk assessment, Frd No 21 continues to be a vital infrastructure for flood control and water resource management in the region.
As an essential component of the local watershed system, Frd No 21 contributes to the overall resilience of the area against flooding risks. With its primary purpose of flood risk reduction, this earth dam stands as a testament to effective water resource management and climate adaptation strategies. The ongoing monitoring and maintenance of Frd No 21 highlight the commitment to safeguarding communities and natural ecosystems from the impacts of extreme weather events.

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 Low 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.
