Summary
Completed in 1941, this Earth-type dam stands at a height of 15 feet and serves multiple purposes including flood risk reduction, hydroelectric power generation, and recreation. With a storage capacity of 125,350 acre-feet and a surface area of 6,400 acres, the dam plays a crucial role in managing water resources in the region.
Managed by the Federal Energy Regulatory Commission, Way Dike E has a high hazard potential and a high risk assessment rating. Despite its condition assessment being labeled as "Not Available," the dam undergoes regular inspections, the last one taking place in June 2019. Additionally, the emergency action plan for the dam was last revised in January 2005, indicating a commitment to safety and preparedness in case of any unforeseen events. With its strategic location and significant impact on the surrounding environment, Way Dike E is a key component in the water resource and climate management efforts in Michigan.
Overall, Way Dike E stands as a testament to the intricate balance between water resource management, infrastructure development, and environmental conservation. As a critical piece of the local hydroelectric infrastructure, this dam not only provides valuable flood protection and recreational opportunities but also contributes to the generation of clean energy. With its high hazard potential and risk assessment, ongoing monitoring and maintenance are essential to ensure the safety and stability of the structure for both the community and the environment it serves.

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.
