Summary

With a height of 8 feet and a storage capacity of 3600 acre-feet, Eagle Lake covers a surface area of 515 acres and is fed by Eagle Creek. The dam has a low hazard potential and a moderate risk assessment, making it a relatively safe structure.

Managed by the Wisconsin Department of Natural Resources, Eagle Lake is regulated, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. Despite being uncontrolled, the spillway at Eagle Lake helps manage discharge during periods of excess water flow. The dam's condition assessment remains unrated, with the last inspection conducted in October 2017.

Eagle Lake stands as a testament to the importance of water resource management and the intersection of human infrastructure with natural ecosystems. Climate and water enthusiasts alike can appreciate the history and functional aspects of this dam, which continues to provide recreational opportunities while safeguarding the surrounding environment.

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.
