Skoyen dam
Skoyen
Skoyen, located in Trempealeau, Wisconsin, is a private earth dam constructed in 1974 by the USDA NRCS for fire protection, stock, and small fish pond purposes. With a dam height of 18 feet and a hydraulic height of 8 feet, Skoyen has a storage capacity of 70 acre-feet and a surface area of 3 acres, serving the local community along TR-King Creek. Despite its low hazard potential, Skoyen's condition assessment in 2017 deemed it unsatisfactory, reflecting the need for maintenance and potential upgrades to ensure its continued functionality.
Managed by the Wisconsin Department of Natural Resources, Skoyen is regulated and inspected regularly to meet state standards for dam safety. The dam's controlled spillway and maximum discharge of 140 cubic feet per second contribute to its risk assessment rating of "Very High (1)", highlighting the importance of proactive risk management measures. While no emergency action plan has been prepared for Skoyen, its location in a high-risk area underscores the necessity of maintaining a vigilant approach to monitoring and addressing potential hazards to safeguard the surrounding community and environment. With Congressman Ron Kind representing the district, ongoing efforts to enhance Skoyen's safety and resilience are crucial in the face of evolving climate challenges and water resource management needs.
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 Skoyen
Where does the data for Skoyen 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.
