The Kishwaukee River basin in northern Illinois remains one of the most mussel-rich resources in the state. In 2012, the INHS Urban Biotic Assessment Program began studying the fishes, reptiles, amphibians, and mollusks of the Kishwaukee River along the Illinois Tollway I-90 overpass. In 2015 UBAP began a longterm monitoring program of the mussel population at the site. Each August, a team of researchers from INHS, IDNR, and local land management agencies descends on the same location and intensively samples the mussels in the area over the course of a week.
