Thornapple River Trout Fishing Conditions
Brown Trout
The Thornapple River in Barry County flows to the Grand River, with brown trout in the cold upper reaches near Hastings. A spring option for southwest Michigan anglers.
The Thornapple is primarily a warm-water river in its lower sections, but the cold springs and tributaries feeding the upper Barry County reach maintain trout habitat through early summer. Brown trout in the Hastings and Caledonia area water provide a local option for anglers in the Grand Rapids south suburbs. Spring is the productive window.
