Chloride Monitoring in Wisconsin

Volunteer Monitoring


Volunteer chloride monitoring in Wisconsin is supported by the Izaak Walton League's Winter Salt Watch program. Volunteers can request FREE chloride test kits, test salt concentrations in local streams and share results back to strengthen this national database.

 The Fox-Wolf Watershed Alliance and Milwaukee Riverkeepers coordinate local monitoring efforts. Check out the data from the Fox-Wolf 2020-21 season on Google Maps.

Active Research

Linnea Rock is a graduate student at the University of Wisconsin Center for Limnology. She works with Assistant Professor Hilary Dugan to study how chloride is changing freshwater and the impact of those changes.  Luckily, winter is Linnea's favorite season so she doesn't mind bundling up for winter field work. At the end of a long field day, she loves to cozy up with hot cocoa and a mystery novel.

Read more about Linnea's research or take virtual field trip with her to gather chloride samples at Pheasant Branch Creek.


Afterwards, you can even visit her in the lab to learn about how she analyzes her samples.
