Great Lakes tributaries deliver pathogens from many different sources. This drawing represents the various sources of these pathogens along with hydrologic, land cover, and season patterns by which they enter the Great Lakes tributaries. It references the virus sampling that took place with the backdrop based largely on the Milwaukee, WI.
