Rock Creek

Rock Creek, near Missoula, Montana, is one of the premier fly-fishing destinations in the state, renowned for its abundant trout population and stunning scenery. Here’s what you need to know about fly fishing on Rock Creek:

Why Fish Rock Creek?

• Blue Ribbon Trout Stream – Rock Creek is classified as a blue-ribbon trout stream, meaning it supports a high population of wild trout.
• Diverse Trout Species – Anglers can catch native Westslope cutthroat trout, rainbow trout, brown trout, and even the occasional brook trout or bull trout.
• Scenic Wilderness Setting – The creek flows through a mix of forested canyons, open meadows, and rugged mountain terrain, offering a true Montana backcountry experience.
• Less Crowded Than the Bitterroot or Clark Fork – While popular, Rock Creek sees fewer anglers than some other well-known rivers near Missoula.

Best Time to Fish

• Spring (May–June) – The Salmonfly Hatch is legendary on Rock Creek. These massive insects bring big trout to the surface for explosive dry-fly action.
• Summer (July–August) – Good hatches of golden stones, caddis, and mayflies keep fish active. As the water drops and warms, mornings and evenings are best.
• Fall (September–October) – Some of the best fishing happens in the fall. Brown trout spawn and become more aggressive, and cooler temps keep fish active.
• Winter (November–March) – Challenging but rewarding for hardcore anglers using nymphs and streamers in slower, deeper pools.

Fly Patterns for Rock Creek

• Dry Flies: Salmonflies, Golden Stoneflies, Caddis, Parachute Adams, Hoppers (in late summer).
• Nymphs: Pheasant Tail, Prince Nymph, Pat’s Rubber Legs, Hare’s Ear.
• Streamers: Woolly Buggers, Sculpzillas, Sparkle Minnows (effective for big browns and aggressive trout).

Access Points

Rock Creek is easily accessible via Rock Creek Road, which runs parallel to much of the river. There are numerous public fishing access points, and the upper sections offer a more remote, wade-fishing experience.

Regulations & Conservation

• Rock Creek is primarily a catch-and-release fishery for native species.
• Be mindful of private property along the river; stick to public land and access points.
• Avoid wading in spawning beds (redds), especially in the fall.
