June is here and summer research is officially launched at both Hasler Lab and Trout Lake Station! We are excited for another fun summer of science and collaboration. Check out this video from our 2026 summer science communication intern Nalina to learn what is happening at TLS. Stay tuned for more updates from Nalina and …
Thank you so much to everyone who supported us during last week’s “Day of the Badger” event. We raised nearly $78,000- far surpassing our goal and allowing us to fund 10 summer research positions! Students will benefit directly through hands-on experiences studying the waters of Wisconsin. Many CFL students continue to pursue further education and …
It’s that time of year again- rain is falling, flowers are blooming, and it’s UW-Madison’s “Day of the Badger.” This annual fundraising campaign is your chance to support the Center for Limnology. Your generosity during this event directly funds student research fellowships both at Hasler Lab in Madison and up north at Trout Lake Station. …
Angling technology has gotten increasingly powerful in recent years. Newly developed forward-facing sonar (FFS) units now give anglers the ability to pinpoint the location and watch the behavior of fish in real time, a seemingly massive advantage. This has led to considerable concerns that new technology could provide an unfair advantage to anglers, making overfishing …
During the winter, many Wisconsinites share in the joys of a frozen lake or other waterbody. Ice fishing, ice skating, skiing, snowshoeing, and snowmobiling are all popular types of frozen fun. The Center for Limnology also deeply enjoys this season, continuing research under the ice and leading educational activities on top of it. Each February, …
by Adam Hinterthuer – It is surreal to be typing these words but – after 15 years – I am saying farewell to the Center for Limnology. In that time, I’ve had the great privilege to help share the stories about – and behind – the world-class science being done from this small, but mighty, …
A recently published video on YouTube chronicles the struggles of Ito, or the Sakhalin taimen. Like many tales of struggling species of fish, the Japanese rivers Ito call home have been reengineered by humans and warmed by climate change. CFL associate professor, Olaf Jensen, helped conduct surveys of this endangered species and one of Jensen’s …
Earlier this winter, Center for Limnology graduate student, Sophia Skoglund, stepped up to a scaled-down version of NASA’s “Hyperwall” presentation screen in a cavernous room of the New Orleans Convention Center. Skoglund was there to tell attendees of the American Geophysical Union’s annual conference about her work bringing satellite data down to earth – or, …
It’s official! Just as we were waking up from ringing in the New Year, the Wisconsin State Climatology Office declared January 1, 2026 as the date that Lake Mendota officially froze for the 2025/26 winter season. Here at the CFL it’s hard to feel like winter has truly begun until the last of Madison’s lakes …
Yesterday evening as sunset was casting a rosy pink band of light across the frozen surface of Lake Monona near Olbrich Park, two people skated across its newly frozen surface. This morning, a semi-frozen Lake Mendota offered flocks of Canada geese, mallards and mergansers rippling open waters to swim in punctuated by long stretches of …
