Limnology (the study of lakes) in North America was developed at the University of Wisconsin by E.A. Birge and Chancey Juday, so it is not surprising that the Center for Limnology Web site contains a wealth of information about their activities and research projects. The site includes a virtual tour of the Center's main research facility on Lake Mendota in Madison and their research center on Trout Lake in north central Wisconsin. More importantly, a page dedicated to research contains valuable information about ongoing research on lake ecology, bioenergetics, and an online system for identifying Wisconsin fishes. An events calendar and employment listing area round out the site.
