Frd No 66 dam
Frd No 66
Frd No 66, also known as the Upper Black Vermillion WS Dam 66, is a local government-owned structure located in Lillis, Kansas. Built in 1973 by the USDA NRCS, this earth dam stands at a height of 21 feet and serves primarily for flood risk reduction along the Irish Creek-TR river or stream. With a maximum storage capacity of 115 acre-feet and a normal storage of 25 acre-feet, it covers a surface area of 5.1 acres and has a drainage area of 0.26 square miles.
Although Frd No 66 has a low hazard potential and is not currently regulated by the state, it plays a crucial role in mitigating flood risks in the region. The dam features an uncontrolled spillway with a width of 40 feet and no outlet gates. While its condition assessment is not rated and the last inspection date dates back to 2010, the risk assessment deems it moderate with a DSAC assigned date yet to be determined. Despite its minimal risk, the dam's emergency action plan status, inundation maps preparedness, and risk management measures remain undisclosed.
Water resource and climate enthusiasts interested in the construction and functionality of Frd No 66 will find valuable insights in its design and purpose. As a key flood risk reduction infrastructure in Marshall County, Kansas, this earth dam showcases the collaborative efforts of local government and USDA NRCS. With its strategic location and hydraulic specifications, Frd No 66 stands as a testament to effective water resource management 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 66
Where does the data for Frd No 66 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.
