This sudden flooding along rivers that empty into the Saginaw Bay is not caused by rain, nor by any dam failure. Is there any sign of a breached dam? There are photos of flooding along the river. It is being blamed on potential dam failures by the frantic Governor who fears what she has been told – that the Seaway is beginning to spread apart as the N American Continent adjusts to its bowing stress, and Michigan is right in the path of danger. Heaving land that resists ripping apart has been noted in Kansas, causing flood waters to back up along the Missouri River.
The geography of Michigan and Wisconsin and Minnesota show what a ripping seaway will do. Wisconsin is ripping open along the Green Bay Peninsula, with many lakes along that path leading to Madison. Duluth, Minnesota has deep rips in the rock where the ripping action was forced to stop the last time the Seaway was under this stress. The hard rock above Lake Superior and Lake Huron will not give. But the soft rock where Lake Erie connects to Lake Huron will give. This is causing Lake Huron near that rip point to heave, causing the waters of Saginaw Bay to backwash along rivers.
