DuPage County trout stocking

Illinois Department of Natural Resources publishes a schedule rather than confirmed stockings; dates can move with weather and fish supply. We check its feed daily. IDNR lists each season's trout sites and opening day, not a date per water; sites are stocked in the days before the opener. Illinois has two trout seasons: spring (opens early April) and fall (opens mid-October), at about 60 ponds, lakes and streams.
