An anchored weather buoy, managed by the UW–Madison Department of Limnology and affectionately nicknamed “David Buoy” (after musician and singer David Bowie) floats above one of the deeper sections of Lake Mendota in Madison, Wis., on a sunny autumn day on Oct. 16, 2024. The buoy has a weather station on top plus records underwater temperature, dissolved oxygen, conductivity and algae levels.

The Center for Limnology.  Global leadership, local impact.

The discipline of Limnology in North America was founded at UW-Madison in the 1890s. After 130 years, the Center for Limnology remains a globally-recognized leader in the field. Our faculty and researchers lead cutting-edge research programs in limnology, aquatic ecology, fisheries, and ecosystem science. Our work aims to understand the world’s aquatic ecosystems, and to inform and inspire their stewardship.

Our core research mission is closely integrated with training the next generation of freshwater leaders – we train graduate students (MS and Ph.D.) through Freshwater and Marine Sciences and Integrative Biology graduate programs. We engage with diverse partners, and share our knowledge and research with a wide range of audiences and users. Field facilities at the Hasler Laboratory for Limnology in Madison, WI and Trout Lake Station in Boulder Junction, WI support our researchers and students, as well as the larger freshwater research community.

Research at the Center for Limnology

Aquatic Invasive Species

What are the impacts of invasive species in lakes and rivers, and what management strategies are effective?

Global Limnology

How are lakes around the world responding to human impacts and global environmental change?

Carbon Cycling

What is the role of lake and river ecosystems in global carbon cycling?

High-tech Limnology

Can we use new technologies and knowledge-guided machine learning to better monitor, model, and manage lakes?

Fish and Fisheries

How can we manage inland and marine fisheries in a rapidly changing world?

Water Quality

How do climate change, pollutants, changing land use, food web perturbations, and other factors influence water quality?

Open Houses at Hasler Lab & Trout Lake Station

Open Houses are an opportunity to get a first-hand look at what research is going on at the CFL and meet the scientists and students conducting it here and all over the world exchanging knowledge and helping to solve global environmental problems. Lots of fun activities for all: boat rides, fishes, ice cream, aquatic-themed crafts, and more.
