Summary
The dam is primarily used for flood control, with a low hazard potential and fair condition assessment. The flowage has a maximum storage capacity of 105 acre-feet, a normal storage of 67 acre-feet, and covers a surface area of 42 acres. Willow Creek Flowage No 3 is state-regulated by the Wisconsin Department of Natural Resources, with permitting, inspection, and enforcement processes in place to ensure its safety and compliance with regulations.
The dam at Willow Creek Flowage No 3 is an earth-filled structure standing at a height of 7.8 feet and a length of 100 feet. It features a controlled spillway with a width of 62 feet and has a maximum discharge capacity of 171 cubic feet per second. The flowage serves as a habitat for fish and wildlife, contributing to the conservation efforts in the area. With its location in a scenic natural setting and its importance for flood control and wildlife preservation, Willow Creek Flowage No 3 stands as a valuable resource for the local community and the environment.
Despite its low hazard potential, the risk assessment for Willow Creek Flowage No 3 indicates a very high risk, possibly due to factors such as aging infrastructure or environmental concerns. Regular inspections and maintenance are crucial to ensure the continued safety and functionality of the dam and flowage. With proper risk management measures in place, Willow Creek Flowage No 3 can continue to serve its purpose as a vital water resource for the region while minimizing potential risks to surrounding areas.

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.
