MADISON (WKOW) — Students in a Zoology class at UW-Madison discovered spiny water fleas in a sample of water from Lake Mendotaâ??s University Bay.
The students were about one-quarter mile offshore on September 11 when they dipped a small net into the lake and started poking through its contents. The net was intended to catch plankton and when the students asked associate professor Jake Vander Zanden to take a look, he was surprised at what he saw.
