Reefs and Quarries, Streams and Fish

Chris wraps up his interviews at the University of Wisconsin-Milwaukee's School of Freshwater Sciences in this episode, where he speaks at length with Dr. John Janssen. Along with sharing insights from his Sea Grant-sponsored work with lake trout and yellow perch, Janssen relates this research to a bigger picture about how Lake Michigan functions (“like a brewery”, according to Janssen) and how people perceive lakes and water in general. Janssen also explains the presence of reefs and quarries in and around the lake, and offers a simple solution to improve the water quality of Lake Michigan.
