Every number on Troutline traces to a public source you can check yourself. These are the agencies and networks we pull from. When a source goes quiet or a number can't be verified, we show nothing rather than guess.
Report snippets come from the local fly shops, guide services, and lodges that actually fish each river. Every report is attributed and links out to the shop that wrote it — Troutline is a distribution channel for shops, never a republisher.
