Mio Dam, Michigan
Mio Dam sits above the Foote Dam, which is the ceiling for the Au Sable River, so no lake run reaches this water.

What the runs do here
No lake run reaches this dam. The Au Sable River's anadromous ceiling is the Foote Dam, downstream of here — fish out of Lake Huron stop there, so salmon and steelhead never arrive at this structure and a run calendar on this page would be an invention.

- Au Sable River 0.1 mi from the dam · Cold transitional large river (MDNR VSEC) · typed Cold-transitional

Coldwater designation is the state's own classification. A dam sits on one river and this list is every designated reach within a mile and a half of it, so a tributary mouth shows up here too.
