Center for Limnology

What Center for Limnology does

The Center for Limnology (CFL) is a university research center within the College of Letters and Science at the University of Wisconsin-Madison, established in 1982 to continue the legacy of E.A. Birge and Chancey Juday — the founders of North American limnology. CFL operates two physical research facilities: the Hasler Laboratory of Limnology on the shore of Lake Mendota in Madison (constructed 1963) and Trout Lake Station in Boulder Junction, Wisconsin (year-round operations since 1967). The center conducts freshwater ecosystem research across six themes: Aquatic Invasive Species, Carbon Cycling, Fish and Fisheries, Global Limnology, High-tech Limnology, and Water Quality, with a flagship North Temperate Lakes Long-Term Ecological Research (NTL LTER) program that has produced decades of continuous lake monitoring data. Its work reaches globally, from the Great Lakes to rivers in Mongolia and lakes in Antarctica.

CFL's 'products' are scientific knowledge, long-term ecological datasets (distributed via the EDI repository), and trained graduate and undergraduate students in freshwater sciences. The center offers MS and PhD programs through UW-Madison's Department of Integrative Biology and the Freshwater and Marine Sciences Certificate program, hosts a weekly research seminar series, and operates the Kaeser Scholar lecture program. Notable research outputs include the development of trophic cascade theory and ecosystem-based management approaches adopted by state and federal agencies.

As a non-commercial academic unit, CFL does not sell products or charge for research output. Funding is sourced from NSF grants (including the NTL LTER program), UW-Madison and Universities of Wisconsin System allocations, and private donations. The center distributes expertise through peer-reviewed publications, the CFL Blog, newsletters, social media channels, public events such as Science on Tap Minocqua, and the 2025 'Learn Your Lakes' mobile citizen science initiative. Stakeholder segments include graduate students (primary), undergraduates, state and federal natural resource agencies, and the general public including local lake associations.

Core offering

The Center for Limnology conducts scientific research, graduate and undergraduate education, and public outreach focused on freshwater ecosystems. Operating through the Hasler Laboratory of Limnology in Madison and Trout Lake Station in Boulder Junction, Wisconsin, the center delivers long-term ecological research, graduate degree programs in limnology and integrative biology, hands-on field research training, and community engagement on water resource stewardship.

Product overview

Center for Limnology (CFL) is an academic research and education center at the University of Wisconsin-Madison, established in 1982. It is not a product or software company. CFL operates the Hasler Laboratory of Limnology (in Madison) and Trout Lake Station (in Boulder Junction, Vilas County) as field research facilities. The center conducts freshwater ecosystem research across six themes: Aquatic Invasive Species, Carbon Cycling, Fish and Fisheries, Global Limnology, High-tech Limnology, and Water Quality. CFL offers graduate and undergraduate education programs, weekly seminars, Kaeser Scholar lecture series, outreach through newsletters and the CFL Blog, and maintains the CFL Archives and Library Services. No commercial software products or technology platforms are offered.

Emerging players

• IIHR—Hydroscience and Engineering, University of Iowa: University of Iowa research center studying fluid mechanics, hydrology, and water resources—comparable academic freshwater research unit with strong engineering, modeling, and policy engagement profile.

Direct peers

• Stone Laboratory, Ohio State University: Ohio State University's freshwater research and education facility on Lake Erie offering research, graduate courses, and field station programs—analogous academic research-and-education center focused on Great Lakes and inland waters.
• Cary Institute of Ecosystem Studies: Independent, nonprofit ecological research institute studying freshwater and terrestrial ecosystems with long-term datasets, graduate training, and science-to-policy translation—closely analogous organizational model and mission to CFL.
• Cooperative Institute for Great Lakes Research (CIGLR), University of Michigan: NOAA-cooperative institute based at the University of Michigan that conducts Great Lakes research on water quality, aquatic ecology, and climate impacts—directly comparable freshwater research institute with similar graduate-training and agency-facing model.
• Michigan State University Institute for Fisheries Research: Michigan State University unit partnering with Michigan DNR on inland lake fisheries research, monitoring, and management—comparable university-based freshwater fisheries research center with state agency collaboration.
• NOAA Great Lakes Environmental Research Laboratory (GLERL): Federal research laboratory conducting interdisciplinary research on the Great Lakes, including long-term monitoring, limnology, and ecosystem modeling—directly comparable in scope, science portfolio, and freshwater focus.
• Hubbard Brook Experimental Forest / LTER: Long-Term Ecological Research program studying watershed biogeochemistry and forest-stream ecosystems—closely comparable as a flagship LTER with continuous long-term datasets, graduate training, and interdisciplinary freshwater research.
• USGS Great Lakes Science Center: U.S. Geological Survey center conducting fisheries and aquatic ecosystem research across the Great Lakes basin with long-term monitoring programs—overlapping research themes (Fish and Fisheries, Aquatic Invasive Species, Water Quality) with CFL.

Others

• GLEON (Global Lake Ecological Observatory Network): International network of lake observatories using high-frequency sensors and shared data protocols—CFL is a participating node, and GLEON is the closest ecosystem-wide peer for CFL's "high-tech limnology" research theme.

Regional players

• Wisconsin Department of Natural Resources (Bureau of Fisheries and Aquatic Sciences): State agency that manages Wisconsin's inland lake and fisheries programs and consumes CFL research; a primary collaborator and counterpart for freshwater management rather than a direct academic competitor.
