Experience water technology and scientific research at the UWM School of Freshwater Sciences.

Water technology and scientific research are the core of activities and education at the UWM School of Freshwater Sciences. During Doors Open, scientists bring examples of their work to a publicly accessible forum where you can walk a circle tour that leads through the research vessel NEESKAY; machine shop; fish ecology, nutrition and aquaculture; beach health; water chemistry; groundwater studies; invasive species; and graduate programs in these areas. Learn water resource issues and ideas for solving them. See food production and fish farming.
