About Troutline
Troutline puts everything you'd check before a fishing trip on one page per river: live flows against the historical median, the hourly forecast, what's hatching, where the stocking truck has been, snowpack, moon phase, and fresh reports from the fly shops on the water. Assembling that picture used to take fifteen browser tabs.
Every number traces to a source you can check — USGS and state gauges, NWS forecasts, agency stocking schedules — and every river gets a written overview in plain language: what the water actually fishes like, when it's on, and when to stay home. When we can't verify something, we leave it off.
We currently cover 269 rivers and creeks across Alaska, Arizona, California, Colorado, Connecticut, Georgia, Idaho, Maine, Michigan, Missouri, Montana, New Mexico, New York, North Carolina, Oregon, Pennsylvania, Tennessee, Utah, Vermont, Virginia, Washington, West Virginia, and Wyoming, and the map fills in steadily — the long-term aim is every major trout water in the country.
