About Illinois Trout Fishing

Illinois trout waters are concentrated in spring-fed streams in the Driftless Area and select stocked locations. Cold groundwater maintains suitable temperatures in these oasis streams surrounded by agricultural land.

Spring is the primary trout season with fresh stockings and optimal water temperatures. Fish are most active from March through May. Focus on newly stocked areas for best action.

Summer (June-August)

Summer fishing is limited to cold spring creeks. Fish early morning when water is coolest. Apple River and other spring-fed streams remain fishable.
