Floating for Science: SRHWG Joins WYACT on the Snake

On July 16, with blue skies overhead and perfect weather, 12 SRHWG members hit the river for a hands-on science float with researchers from the University of Wyoming’s WyACT (Wyoming Anticipating the Climate-Water Transition) project. The group floated the stretch of the Snake River between Jackson Lake Dam and Pacific Creek Boat Launch, while learning about thermal habitats and how rising water temperatures may impact the native Yellowstone Cutthroat Trout.

Along the way, researcher Chuck Williams and his colleagues demonstrated the use of FLAMe (Fast Limnological Automated Measurements) technology—an innovative system for collecting fine-scale water quality and temperature data while in motion. He explained how thermal heterogeneity—the variation in water temperature across space and time—supports biodiversity and provides essential cool-water refuges that help fish beat the heat. With observed water temperatures exceeding 68 degrees already this summer, understanding these patterns is becoming increasingly urgent.

Participants got a firsthand look at how science and stewardship go hand in hand. The float sparked great conversation, connection, and new insights into climate-water dynamics in the Upper Snake. “I always learn a lot when I get outside with the people who are keeping track of our water. I like to say let’s “measure what matters.” Thanks for letting me see the work in progress.” Phil Powers,  Executive Director, Protect Our Water JH.

Huge thanks to WyACT, David Cernicek with the Bridger-Teton National Forest for rowing an extra boat, and the Grand Teton National Park Foundation for keeping us fueled with snacks and drinks!
