Summary
Constructed in 1848, this timber crib dam stands at a height of 13 feet with a hydraulic height of 23 feet, providing a surface area of 9 acres and a normal storage capacity of 30 acre-feet. With a low hazard potential and fair condition assessment, the dam continues to be a safe and enjoyable destination for outdoor enthusiasts.
Managed by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), the Frankenmuth Dam is subject to state regulation, permitting, inspection, and enforcement to ensure its structural integrity and public safety. The dam features an uncontrolled spillway with a width of 235 feet, allowing for the controlled release of water during periods of high flow. Despite its age, the dam has undergone periodic inspections, with the last assessment conducted in October 2019, indicating a moderate risk level with appropriate risk management measures in place.
With its historical significance and ongoing recreational value, the Frankenmuth Dam stands as a testament to the enduring importance of water resources in shaping the landscape and culture of Michigan. As climate change continues to impact water availability and quality, the maintenance and preservation of such structures become increasingly critical to safeguarding both human and environmental well-being in the region. Explore the Frankenmuth Dam to experience the intersection of nature, history, and community in this picturesque corner of Saginaw County.

Dam Data Reference
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.
