Phosphorus holds the infamous reputation of being the most problematic excess nutrient in our lakes, as readers of our blog will know well. But let’s not forget about nitrogen. Nitrogen (N) is an essential nutrient for all life in our waters as a key building block for proteins, and for chlorophyll in primary producers like …
By Nalina Cherr– Can you believe it’s really almost the end of summer? I can hardly believe that this is the last day I will be typing at my desk in the bullpen at Trout Lake Station (TLS). Before I head out, I want to tell you about my independent project, and say a few …
By Nalina Cherr- July 31st was rainy, but that did not stop a flood of people from rushing to Trout Lake Station (TLS) in Boulder Junction for our 15th annual Open House. More than three hundred visitors poured in to talk about freshwater science, play games, make art, and enjoy scoops of Babcock ice cream. …
Every week this summer, graduate student Aubrey Wendorff and her undergraduate interns can be found scaling river banks and wading through mud to test the waters around Madison for chloride. Chloride, the anion component of common road salts (NaCl), is dissolved in water and can be measured in the lab from water samples or inferred …

However, it can be hard to predict the exact timing and the exact culprits. At the Center for Limnology, researchers in Trina (Katherine) …
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 …
