In early October a crew from the Columbia FWCO headed northeast to the Chicagoland area once again in search of Asian carp. As with the previous trips, there were five fixed sites to sample on different locations of the Chicago Area Waterway System (CAWS).

These sites extended from up north near Skokie, IL on the North Shore Channel down to the Cal-Sag Channel and Lake Calumet around Dolton. While the crew had their eyes trained to look for invasive silver and bighead carp, only the usual suspects were captured, the majority being gizzard shad, yellow perch, Centrarchids (basses and sunfish), common carp and several different minnow species.

Luckily, no Asian carp were discovered at any of the sites, although the crew did have a bit of excitement while sampling in Lake Calumet (the site nearest to Lake Michigan where a live Asian carp has been captured). During one of the electrofishing runs, a silvery fusiform shape was rolled by the electrical current. The crew was stunned for an instance thinking it may be an Asian carp, but getting a better look realized it was a king salmon.

Other interesting species that were found include central mudminnow, banded killifish, oriental weather loach and a Louisiana red swamp crayfish. This trip was part of a continuing effort between the Illinois Department of Natural Resources, U.S. Army Corps of Engineers, and the Carterville, Columbia and Lacrosse FWCO's.
