Summary

With a primary purpose of recreation, this Earth-type dam stands at 11 feet tall and spans 450 feet in length. The lake boasts a storage capacity of 168 acre-feet, with a normal storage level of 40 acre-feet and a surface area of 22.8 acres.

Serving as a popular recreational spot, Partridge Lake offers opportunities for fishing, boating, and wildlife observation in a picturesque setting. The dam's low hazard potential and not rated condition assessment ensure the safety of visitors and nearby residents. While the last inspection took place in 2011, the dam's emergency action plan was last revised in 1995, indicating a need for updated safety measures in case of potential risks.

Climate enthusiasts and water resource advocates can appreciate Partridge Lake for its contribution to the local ecosystem and community recreation. As a regulated water source with state permitting, inspection, and enforcement in place, the lake provides a sustainable environment for outdoor activities while maintaining safety standards. With its tranquil waters and scenic surroundings, Partridge Lake stands as a valuable asset in the conservation and enjoyment of natural resources in Wisconsin.

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. 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

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, 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.
