Live USGS conditions and guide-quality fishing reports for 101 major US trout rivers. Click any river for real-time flow data, active hatches, hot spots, and fly recommendations.
Trout Bible pulls live streamflow data directly from the USGS National Water Information System — the same data professional fishing guides use before heading to the water. Flow rates are measured in cubic feet per second (CFS) and gauge height in feet, updated every 15 to 60 minutes at thousands of stations across the United States.
Each river page includes a current conditions report with active hatches, hot spots, recommended flies with specific commercial names, wadeability rating, gear setup, access points, and key regulations — everything you need to plan a productive fishing trip.
Whether you're planning a trip to the South Platte River in Colorado, the Madison River in Montana, the Beaverkill in New York's Catskills, or the Deschutes in Oregon — Trout Bible has current conditions and a detailed guide report ready for you.
