The Illinois River is open for trout fishing using flies and lures only. This is mostly a catch & release trout fishery and only adipose-clipped trout can be harvested. As temperatures start to cool, more trout should start biting. Consult the fishing regulations for more information and locations open to fishing. Tributaries, including East Fork and West Fork Illinois, are closed to angling. The seasonal closure to all angling from 8-dollar Bridge to the former Pomeroy Dam site is in effect until November 30.
