Come fish! Rock creek is one of the better options in SW Montana right now.
Flows are high but on the drop. Floating and fishing has been the best way to get at the fish, while side channels and bank fishing has been good.
We expect to see caddisflies, green drakes, and maybe salmonflies soon. It is worth trying any one of these dry flies to catch fish on top. Try a worm or bwo nymph dropper with the drake or salmonfly dries.
Streamers have been picking up a good amount of fish, too. See below for fly suggestions.
If you're floating, be safe. If in doubt, scout it out. Wear a life jacket.
Here are a few tips for fly fishing Rock Creek:
1. Fish the side channels, slow inside deeper bends, runs with a couple feet of walking speed water and structure, riffles, and undercut banks.
2. Try swinging or stripping a copper/gold kreelex minnow in any walking speed water you can find along the banks, and at these flows even up along the grassy drop-offs if the water is in the grass.
3. Try a black and purple, or peach chubby with a medium length dropper of a hot bead worm or pink pearl core worm.
Here are a few fly suggestions:
1. Black and purple chubby size 10-12
2. Purple Haze size 12-20
3. Elk hair caddis size 14
4. Kreelex Minnow size 6, in copper/gold
5. TJ Hooker size 10-12, in coffee/black
6. Pheasant Tail Nymph size 12-20
7. Hot Bead San Juan Worm size 10, red with a hot orange bead
