The "Sixth Street" Fish ladder downtown has one of the largest salmon, steelhead and migratory trout passages in the world with an estimated, 100,000 fish swimming through the ladder. (Sixth Street fish ladder pictured below.)
The best time to fish the Grand and Rouge Rivers is during the Spring and Fall.
Another great river is the Rogue, Located less than ten miles from the greater Grand Rapids area. The Rogue River runs right through the town of Rockford. Some of the best places to are under the bike bridge, and behind the paper mill. The Rogue has some great wading opportunities for resident Brown and Rainbow trout. This river has clean, clear water, and offers excellent fishing!
Just a little further North, is the Muskegon River. The Might Mo excels in big numbers of Steelhead, Salmon, and resident Trout. Although mostly a private river, the Muskegon also offers great wading and boat fishing. It's a tailwater fishery and offers the best trout fishing in Michigan.
