West Fork Kickapoo 4 dam
West Fork Kickapoo 4
West Fork Kickapoo 4, also known as Hidden Valley, is a flood risk reduction structure located in Vernon, Wisconsin. Built in 1966 by the USDA NRCS, this earth dam stands at 46 feet high and spans 615 feet in length. With a normal storage capacity of 95 acre-feet and a maximum discharge of 2170 cubic feet per second, the dam plays a crucial role in managing water flow in the region.
Managed by the Wisconsin Department of Natural Resources, West Fork Kickapoo 4 is regulated, inspected, and enforced by state authorities to ensure its safety and functionality. Despite being classified as having a low hazard potential, the dam is assessed to be in fair condition as of September 2020. With a moderate risk assessment rating, the structure is monitored and maintained to mitigate any potential risks and ensure the safety of surrounding communities.
In addition to flood risk reduction, West Fork Kickapoo 4 also serves recreational purposes in the area. With a surface area of 16 acres and a drainage area of 5.2 square miles, this dam not only safeguards the community from flooding but also provides opportunities for outdoor activities. As a significant water resource in the region, it plays a vital role in water management and climate resilience efforts.
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.
Plan around the weather

About West Fork Kickapoo 4
Where does the data for West Fork Kickapoo 4 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.
