Summary
Owned by the state of Wisconsin and regulated by the Wisconsin Department of Natural Resources (WIDNR), this Earth-type dam stands at a height of 6.1 feet with a length of 19,952 feet. It has a storage capacity of 2,000 acre-feet and serves the primary purpose of controlled spillway for flood control.
Despite being assessed as in fair condition during the last inspection in June 2019, Shiocton Mitigation poses a low hazard potential and is deemed to have very high risk due to its critical role in mitigating water resource issues in the area. With a history of state inspection, permitting, and enforcement, this structure is actively managed to ensure its safety and effectiveness in managing water flow and climate-related challenges. The proximity of the dam to the Detroit District and the involvement of state agencies highlight the collaborative effort in water resource management in Outagamie County.
In the event of an emergency, the structure has protocols in place, although the last update to the Emergency Action Plan (EAP) was in 2013. With a focus on risk management and mitigation measures, Shiocton Mitigation serves as a vital infrastructure for the region, underlining the importance of proactive monitoring and maintenance to address the impacts of climate change and ensure the resilience of water resources in the area.

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.
