Tailwater or freestone: know what you are choosing

Tailwaters (Bighorn, White, Green, North Platte) run cold and stable below dams: fish densities are enormous, hatches are dependable, and the river fishes twelve months a year: but flows change on a hydropower schedule, so the gauge on each report page is your first read. Freestones (Madison, Gallatin, Eagle) breathe with the seasons: runoff blows them out in late spring, then they fish gloriously all summer. The honest play: tailwaters for winter and shoulder seasons, freestones for the July-October glory run.

Flows are the forecast

Every river page on this site carries its USGS gauge trend: learn each river's magic range and check it before driving. As rules of thumb: the Bighorn wades best under ~3,500 cfs, the Green under ~1,500, the Madison fishes through almost anything but crosses carefully above 1,200. Rising water after rain often triggers the best streamer fishing of the year: falling-and-clearing means dry-fly weather.

Common questions

What is the best trout river in America for a beginner?

The Madison between Quake and Ennis: forgiving pocket water where a high-floating attractor dry and a rough drift still catch fish, with public access laddered the whole way. The Green's A Section is the runner-up: you can see the fish, which teaches faster than any book.

When is runoff and should I avoid it?

Roughly mid-May to late June in the Rockies. Avoid freestones then: but tailwaters (Bighorn, Green, North Platte) shrug it off, which is exactly when to book them.
