Photo gallery A deep dive into the life in our waters
Attendees learned all about the waters of Wisconsin and the world at the Limnology Open House at the University of Wisconsin–Madison Hasler Laboratory of Limnology on June 20. They met some of the plants and animals living in our lakes, both under microscopes, in aquariums and in a ride on a research boat.
