Dan Small takes a tour of a portion of the Illinois River near Havana,Illinois a small town south of Peoria, with Kevin Irons, a biologist with the Illinois Natural History Survey, and Dr. Greg Sass, who directs the Illinois River Biological Station. They were in search of the invasive silver Asian carp which are not only a physical hazard to recreational boaters, but they present an environmental problem as well. Debby Wolniak explores the caves at Ledgeview Nature Center with naturalist Ron Zahring. In this week's archival flashback segment from 1984, Dan and Tom Newbauer take their sons fishing on a pond in Waukesha County.
