I have twice made trips to the Muskegon River in Michigan. It is a very pretty river for the great lakes and has lots of interesting water to fishing. From Croton Dam down to Newago the river runs in a deep and heavily wooded valley. below newago I remember the river bottom getting sandier and the current become more laminar and slow.
Access is limited and flating or boating the river seems to be the best way to access the best fishing water. Jet boats are a great way to move from spot to spot, but I dont have one of those, so the next time I return I will use my Watermasters and just hire a shuttle service.
I have caught a few steelhead on the Muskegon and I really look forward to catching a few more.
