Summary
Built in 1941, this earth dam stands at a height of 25 feet and spans 2,985 feet in length. It has a storage capacity of 125,350 acre-feet and serves multiple purposes, including flood risk reduction and recreational activities. The dam is situated on the Michigamme River and is under the jurisdiction of the Federal Energy Regulatory Commission.
Despite its age, Way Dike B-C is designated as having a high hazard potential, indicating the importance of regular inspections and risk management measures. The dam has not been subject to recent condition assessments, but it is crucial for water resource and climate enthusiasts to monitor its status, especially given its significant impact on the surrounding area. With a drainage area of 645 square miles and a maximum discharge capacity of 17,000 cubic feet per second, the dam plays a critical role in water management and energy production in the region.
As a public utility structure owned by the Federal Energy Regulatory Commission, Way Dike B-C serves as a key component of the local water infrastructure. It is essential for stakeholders and decision-makers to stay informed about the dam's condition and operation to ensure the safety of the community and the sustainability of the water resources it manages. With its historical significance and ongoing importance for hydroelectric power generation, Way Dike B-C represents a vital piece of Michigan's water resource management landscape.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
