ILLINOIS RIVER: Trout, steelhead
The Illinois River is open for trout and steelhead fishing using flies and lures only. Water levels have started to drop into shape after last week's rain. The next few weeks would be a good time to hit the Illinois. Click here for river flow and river forecasts. Swinging spoons in 3-6ft deep choppy runs can be very effective this time of year. Bobber and jig are also a good setup that will let you cover longer pools or runs. Consult the fishing regulations for more information and locations open to fishing. Tributaries, including East Fork and West Fork Illinois, are closed to angling.
