Summary

Built in 1864, this private-owned earth dam plays a crucial role in regulating water levels for recreational purposes in the area, specifically along the Wabasis Creek. With a height of 11 feet and a length of 60 feet, the dam has a storage capacity of 60 acre-feet, providing a surface area of 11 acres for recreational activities.

Managed by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), the Wabasis Lake Level Control Structure has been inspected regularly to ensure its satisfactory condition and low hazard potential. While the dam features an uncontrolled spillway design with a width of 10 feet, it has a maximum discharge capacity of 690 cubic feet per second. The surrounding area, including Morgan Lake, benefits from the recreational opportunities and water management capabilities provided by this historical structure, making it an essential component of the local ecosystem.

As a focal point for water enthusiasts and climate advocates, the Wabasis Lake Level Control Structure stands as a testament to the importance of sustainable water resource management in Michigan. With its moderate risk rating and state-regulated status, this dam not only supports recreational activities but also plays a crucial role in maintaining the ecological balance of the region. By staying true to its purpose and undergoing regular inspections, this historic earth dam continues to serve as a vital asset for the community, showcasing the intersection of environmental stewardship and recreational enjoyment.

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.
