Conditions & the best window
The prime bite is dawn and the last hour of light, strongest around the new and full moon. Today's sky on the South Fork of the Snake River looks clear skies (about 0% cloud) — and an overcast day can actually keep fish looking up. Watch the flow as much as the sky: a sharp change in discharge, up or down, can turn the fish off for a day.
The Palisades-to-Irwin and Conant-to-Byington floats are the classic days, and this is fundamentally a boat river at summer flows. The canyon section holds the best cutthroat water. Because the level is set by irrigation rather than weather, check the release rather than the forecast before you go.
