Sturgeon, W.Br. (Menominee R. trib.) - Metropolitan to Calumet Mine Road (5.77 miles) (MI)
Approximate - nearest available gauge. Use as general reference only.
Topo map shows a mill pond (long gone, as it does not show up in satellite views), followed by 30' of drop in a rather short distance starting about here.
Just shy of 1.5 miles of flatwater paddling you'll likely see some buildings (river-left shore), and immediately downstream, as trees close in, the gradient begins.
