A new tool to process water rights and track water availability on California’s North Coast
Trout Unlimited and The Nature Conservancy partner with Foundry Spatial to build an online tool to protect summer stream flows During the heat of summer, endangered salmon and steelhead in California’s North Coast streams face a fundamental problem: There often isn’t enough cold water to support fragile populations of juvenile fish. Flows in these coastal…

Spot trout, catch trout, photograph trout… for science
By harnessing the power of angler catch data, it uses artificial intelligence and machine learning to identify individual fish from angler-submitted photos.
Picture this, you’re on your favorite river, you spot a nice trout sipping off the surface. After careful observation, you tie on a fly you think matches. Then you watch this fish for a few more minutes, cast, land your fly just ahead of the sipper, and much to your delight, it raises its head,…

Sirianni, a graduate student at the University of Wisconsin-La Crosse, recently held a field demonstration day on Maple Dale Creek near Viroqua, Wisc., to introduce his master's degree…

TU Science: Measuring the carbon benefits of restored floodplains
While Trout Unlimited’s river and floodplain restoration is often aimed at trout and salmon species, the benefits of our work extend far beyond fish habitat. When a stream channel is reconnected to its floodplain, key complexity and ecological processes are restored. The riparian habitat becomes more diverse, composed of a mosaic of side-channels, wetlands, willow…
