Frd No 6-1 dam
Frd No 6-1
Frd No 6-1, also known as Upper Verdigris Watershed Dam 6-1, is a local government-owned structure located in Virgil, Greenwood County, Kansas. Built in 1963 by the USDA NRCS, this earth dam stands at a height of 37 feet and serves the primary purpose of flood risk reduction in the area. With a storage capacity of 813.55 acre-feet and a drainage area of 2.22 square miles, Frd No 6-1 plays a crucial role in managing water flow from the Verdigris River to prevent flooding in the region.
This dam features an uncontrolled spillway with a width of 60 feet and has a hazard potential rated as low. The structure has not been assessed for its condition but is noted to meet regulatory requirements in Kansas, with state permitting, inspection, and enforcement in place. The risk assessment for Frd No 6-1 indicates a moderate risk level (3), highlighting the importance of ongoing monitoring and management to ensure the safety and effectiveness of the dam in mitigating flood risks in the area.
Despite its age, Frd No 6-1 continues to serve as a critical infrastructure for flood risk reduction in the Upper Verdigris Watershed. With its strategic location along the Verdigris River, this dam plays a key role in protecting the surrounding communities from potential flooding events. As water resource and climate enthusiasts, it is essential to recognize the significance of structures like Frd No 6-1 in safeguarding our environment and supporting sustainable water management practices in the region.

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 6-1
Where does the data for Frd No 6-1 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.
