Summary

This 10-acre fish and wildlife pond was completed in 1995 and serves as a vital habitat for various species in the area. With a normal storage capacity of 35 acre-feet and a maximum discharge of 155 cubic feet per second, this flowage plays a crucial role in supporting the local ecosystem.

Managed by the Wisconsin Department of Natural Resources (WIDNR), Navarino 15 Ac Flowage is regulated, inspected, and enforced by the state authorities to ensure its safety and efficiency. The low hazard potential and not rated condition assessment highlight the reliability of this earth dam structure. The flowage's significance extends beyond its primary purpose, as it also serves as a recreational spot for water and climate enthusiasts to observe and appreciate the surrounding wildlife.

Located near the unnamed tributary to Wolf River, Navarino 15 Ac Flowage offers a peaceful retreat in the midst of nature. With its tranquil waters and diverse ecosystem, this state-managed water resource stands as a testament to the importance of preserving and protecting our natural environment for future generations to enjoy.

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.
