Salmonfly Hatch Week

Pteronarcys californica · dry-fly hatch float

4.98 · 217 floats Big Hole Country, Montana Barbless · Wet-Hand Release
Guided By Riverstone Anglers

The most willing wild trout in the drainage.

One day, one stretch of freestone river, and the wild trout that make Rock Creek worth the drive. We walk and wade the seams and pocket water on foot, reading the river run by run. Gear, flies, and local knowledge included — bring yourself and a license.

The reward is days that feel earned: few boats, native water, and fish that still behave like wild fish. We handle every one wet and send it home strong.

Dry-Fly First
Sight-fishing risers in clear freestone river seams.
Small Party
One guide, 2 rods max — never a crowd on the water.
Gear Provided
Rods, reels, flies, and waders — bring yourself and a license.

Water & Region

The freestone river, up close.

A classic Montana freestone — cold, clear, and tumbling out of high country. Summer flows drop and clarity climbs into a dry-fly dream. We read it daily and put you where the fish are holding.

Before You Book

Before you wade in.

Not at all. Roughly half our anglers are picking up a fly rod for the first time. Your guide teaches casting, reading water, and presentation as you go. Seasoned anglers, just tell us and we'll point you at the technical water.

A valid Montana fishing license, polarized sunglasses, a hat, sunscreen, and layers for changing weather. We supply all rods, reels, flies, waders, and boots. A rain shell is smart any month.

Yes — every trip is barbless, catch-and-release. The wild trout is a wild, self-sustaining resource, and protecting the fishery is the whole point. We handle every fish wet, photograph fast, and return it to the current.

We fish in light rain — trout often eat best under cloud. If conditions become unsafe (lightning, blowout flows), we'll reschedule or refund the day. Your guide makes the call with your safety first.

Absolutely. This listing is a single full day, but we run multi-day trips and wilderness camps on request. Tell us your dates and party and we'll build an itinerary around the best water for your week.
