Summary
The dam, completed in 1953, serves primarily for recreational purposes, offering a serene environment for water enthusiasts. It stands at a height of 12 feet and has a hydraulic height of 11 feet, with a length of 900 feet and a storage capacity of 858 acre-feet. The dam is situated on Le Vassuer Creek and has a surface area of 165 acres, providing a picturesque setting for various outdoor activities.
Managed by the Michigan Department of Environment, Great Lakes, and Energy, the Lake Le Vasseur Dam is regulated, permitted, inspected, and enforced by the state agency to ensure its safe operation. The dam features an uncontrolled spillway with a width of 210 feet, and its hazard potential is classified as low, with a satisfactory condition assessment as of August 2020. Despite a moderate risk rating, the dam's risk management measures are not specifically outlined, highlighting the importance of ongoing monitoring and maintenance to mitigate potential hazards and ensure public safety.
In the heart of the natural beauty of Marquette, Michigan, the Lake Le Vasseur Dam stands as a testament to the harmonious coexistence of water resources and human recreation. With its tranquil waters and lush surroundings, the dam offers a peaceful escape for outdoor enthusiasts seeking to connect with nature.

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.
