Open House Trout Lake Station 2011 - CFL
A group of visitors takes a look at a running experiment testing how long certain invasive snails, crayfish and plants can survive out of water and, presumably, on board any of the boats that visit Wisconsin lakes every year. John Havel and Susan Knight, along with a team of undergraduate students, are running the experiment.
