Frd No 20 dam
Frd No 20
Frd No 20, also known as Wakarusa Watershed Dist 35 Frd 20, is a flood risk reduction structure located in Shawnee, Kansas. Owned by the local government and regulated by the Kansas Department of Agriculture, this dam was completed in 1978 by the USDA NRCS. Standing at a height of 40 feet with a hydraulic height of 37 feet, this buttress dam spans 895 feet and has a storage capacity of 409 acre-feet.
The primary purpose of Frd No 20 is flood risk reduction, serving to protect the surrounding area from potential flooding events. With a low hazard potential and a condition assessment that is currently not rated, this structure plays a crucial role in managing water resources in the region. Although the dam has not been inspected recently, it is designed to meet regulatory standards and is equipped with outlet gates to control water flow.
Despite its age, Frd No 20 continues to function effectively in reducing flood risks and safeguarding the community. As climate change brings about more extreme weather events, structures like Frd No 20 become increasingly important in mitigating the impacts of flooding and ensuring the resilience of water resources in the area. With its history of successful flood risk reduction and ongoing regulatory oversight, Frd No 20 remains a vital asset in the region's water management infrastructure.
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 Frd No 20
Where does the data for Frd No 20 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.
