The Center for Limnology was established in July 1982 to plan, conduct, and facilitate inland freshwater research. The Center grew out of almost one hundred years of limnology at the University initiated by E.A. Birge and Chancey Juday, who founded limnology in North America through extensive descriptive and comparative studies.

The Center's roots were further developed by Arthur D. Hasler, who led the way in experimental limnology and facilitated four decades of aquatic studies at Wisconsin. The present program builds on these approaches and has expanded to include long-term studies, synthesis, modeling, Great Lakes research, and application to resource management and environmental issues.
