🎣 Happy National Go Fishing Day! Whether you’re casting a line in a shady mountain stream or soaking up the sun by a western river, we hope you’re enjoying some of the best fishing spots the Western U.S. has to offer. But as droughts grow more frequent, they’re putting serious pressure on cold-water fish like trout. That’s where USGS scientists at the Northern Rocky Mountain Science Center come in. Together with Montana State University, they’ve developed a Drought Early Warning System to help protect these iconic fish. Using real-time streamgage data and trout biology, we provide streamflow and trout population forecasts so fisheries managers can make smart, science-based decisions. You focus on catching trout—we’ll keep working to make sure there are still trout to catch. 🐟 Learn more about the Drought Early Warning System by clicking the link in today’s USGS story. 📸1: Graduate student fly fishing in Montana.
