Summary

Situated along the W Br Trout Creek, the dam is regulated by the Michigan DEGLE and undergoes regular inspections to ensure its satisfactory condition and low hazard potential.

With a spillway width of 14 feet and a maximum discharge capacity of 230 cubic feet per second, Calderwood Walleye Pond Dam serves as a crucial water resource management system for the surrounding area. The dam's surface area covers 13 acres, impacting a drainage area of 1.1 square miles. Despite its moderate risk assessment rating, the dam's risk management measures and emergency preparedness protocols remain unspecified, highlighting potential areas for further improvement and development to enhance its overall safety and resilience in the face of climate change impacts.

As enthusiasts in water resource and climate conservation, it is essential to monitor and advocate for the continual upkeep and enhancement of structures like Calderwood Walleye Pond Dam. By staying informed about its regulatory oversight, maintenance practices, and risk management strategies, stakeholders can contribute to the sustainable management of this critical infrastructure for both water supply and environmental protection in the Ontonagon region of Michigan.

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.
