Beers, backcountry, e-bikes: Angler scientists at work
A volunteer chapter in Washington State is going the distance to collect trout and salmon eDNA samples in their home water Fed by glaciers and deep snowpack, the Nooksack River joins the Pacific Ocean near Bellingham, Washington, a half-hour drive south of the Canadian border. Upstream, the basin’s cold headwaters originate high in the Cascade…

Because We Will Feel It First, Arizona Must Lead on Climate Change
Arizona’s Senators must continue to lead on climate issues in Congress and with the Biden Administration Today, hunters and anglers are on the front lines of climate change. We are not only seeing significant decreases in snowpack and water levels in formerly perennial streams but are also witnesses to the impacts of weakening monsoon activity…

Tracking trout on the Deerfield
Data collected, scientists now set out to gauge how flows affect the river’s wild browns For the past two-plus years, TU’s Deerfield River Watershed Chapter members and community volunteers have been tracking the movements of 30 brown trout carrying surgically implanted radio transmitters. Now, after putting thousands of miles on their cars to collect 24 million…
