River Conditions
Flows bumped up again this morning to 13,975 cfs out of Palisades Dam. For some perspective: our peak flow last year was 14,000 cfs, so we’re likely at or very near the high-water mark for 2026. The river is running big and cold, clear-to-slightly-off-color, with the best clarity in the upper reaches near the dam. Visibility is sitting around 2–4 feet in most sections. Wading is extremely limited right now — float fishing is the way to go.
Spring runoff is in full swing, and yes, the river looks intimidating. Here’s the thing we’ve learned from a lot of years doing this: the big fish are still eating. They just aren’t eating where they were two weeks ago.
The Good News: Crowds Are Headed Elsewhere
The Salmon Flies just started popping on the Henry’s Fork. That’s where a lot of the regional traffic is going to be this week, and that means the South Fork is going to be noticeably quieter. If you’ve ever wanted to have stretches of this river largely to yourself, this is the week.
Tactics: Search and Destroy, Not Fire and Forget
At these flows, the win is in where you fish, not how much river you cover. The fish are pushed out of the main current and into pockets of slow water — and your job is to find those pockets and work them hard.
Where to look:
- Slow water behind islands, logs, boulders, and any obstruction that breaks the current
- The downstream end of eroding banks — if a big bank is cutting and losing material, there’s almost always a big fish parked in the soft water at the tailout, waiting for whatever the river hands him
- Back eddies and inside seams where the current slows down
- Deep buckets and soft pockets along the edges
Slow down. Pick your water deliberately. Two or three good drifts through a high-percentage spot will out-fish a hundred casts down a fast bank every single time.
Recommended Flies
This is a big-bug, bright-bug game right now.
Nymphs:
- Big stonefly nymphs — Pat’s Rubberlegs in black, brown, and coffee/black, #4–8

- Standard droppers: Zebra Midges #18–20, Pheasant Tails #16–18
Streamers:
