The Blackfoot is on the drop at 3,060 cfs and 55.6°F, with clarity steadily improving as runoff recedes — fish are active all day and looking up tight to the banks. Salmonfly adults are on the water now, Golden Stones are building, and early Green Drakes, PMDs, and caddis are adding to the action.

Hatch Chart
| Insect | Size | Activity | Prime Time |
|---|---|---|---|
| Salmonfly (Pteronarcys californica) | #4–6 | Peak — adults clustered on streamside vegetation, fish looking up | Midday through late afternoon |
| Golden Stonefly | #6–8 | Building — increasing numbers throughout the river | Afternoon |
| Green Drake (Drunella grandis) | #10–12 | Early emergence — sporadic, watch for rising fish | Late morning to early afternoon |
| Pale Morning Dun (PMD) | #16–20 | Active — steady subsurface and surface activity | Late morning |
| Caddis (Brachycentrus / Hydropsyche) | #14–18 | Active — adults and emergers on the water | Evening |
Best Time Window
- Late morning (10 AM – 12 PM): PMD and early Green Drake emergence in softer seams and side channels
- Midday to mid-afternoon (12 PM – 4 PM): Peak Salmonfly and Golden Stone adult activity — prime dry fly window along timbered banks
- Evening (6 PM – dusk): Caddis activity picks up in riffles and runs; swing soft hackles through the tail-outs
Guide's Tip
From the benchWith the Blackfoot on the drop and Salmonflies fully out, now is the time to be on the water — this hatch window is short and the fish know it. Work your boat tight to the bank, casting within inches of timber, willow roots, and submerged logs where big trout are ambushing adults. A dry-dropper rig with a large attractor dry and a stonefly nymph underneath is the most efficient way to cover water and capitalize on both surface and subsurface feeders. Keep an eye out for Green Drake activity late morning — when those big mayflies start popping, put down the stonefly rig and switch to a smaller dry for some of the most exciting dry fly fishing of the year.
