Summary
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
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
