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 Yellowstone River looks partly cloudy (about 47% 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.
Paradise Valley from Carbella to Mallards Rest is the classic float, with even, readable water that suits a drift boat; the town stretch through Livingston has a steeper gradient and fishes best once flows drop below about 7,000 cfs. Wait out the runoff — the river is unfishable through most of May and June and then turns on hard.
