Summary

The dam stands at a height of 18 feet and has a maximum storage capacity of 5,300 acre-feet, serving a drainage area of 188 acres. With a controlled spillway type and a high hazard potential rating, Chute is regulated by the Wisconsin Department of Natural Resources and undergoes regular inspections to ensure its satisfactory condition.

The North Branch Oconto River flows through Chute, providing a scenic backdrop for outdoor enthusiasts to enjoy recreational activities such as fishing, boating, and wildlife observation. The dam's structural height of 18 feet and hydraulic height of 13 feet contribute to its efficient water management capabilities, with a maximum discharge capacity of 4,600 cubic feet per second. Despite its very high risk assessment rating, Chute has implemented risk management measures to mitigate potential emergencies and ensure public safety.

Managed by the local government, Chute is a vital water resource in the region, offering both flood control and recreational opportunities for residents and visitors alike. With its historic significance and ongoing maintenance efforts, Chute remains a focal point for water resource and climate enthusiasts interested in sustainable dam management practices and environmental stewardship in Oconto, 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.
