My curiosity got the best of me and wanted to ask the board what your biggest catches were on the smallest flies. Photo's would be great but love a good fishing story if you have a tale to tell.

I have caught many trout on dry flies down to size 24 and 26. And only a few were trout over 18 to 20 inches. I had one of the best few hours of dry fly fishing of my entire fishing life, on the San Juan River one autumn afternoon, on a size 24 blue winged olive and 7 X tippet.

This reminded me of this:

Didn't know of this exclusive 20/20 club. Thanks for sharing!

Interesting question, most of the time the difficult trout will only take the smallest imitations but are hard to land on such a small fly, the attached fell to a #20 cdc caddis. In another area, I have often found the hammered steelhead and salmon go for a smaller bug just cause it is different.

I got a 24" brown on a # 20 BWO on the Missouri right by the area with the old railroad tunnels.

For me a size 18 Chromie caught me a fish that may have went 6 pounds. It also caught me a fish about 2 pounds that then caught me a loon about 4 pounds that made several screaming runs before I snapped him off. My partner took an 11.5 (weighed) up in the Cariboo a few years ago on a size 16 Chromie, Big fish like that seem to be showing up less and less recently.

22" brown on a #20 Rainbow Warrior.

I've also caught a few big fish during trico and BWO hatches. It will be a couple months before I cast a dry fly

The thing to consider is proportional relationship. Size of fly to size of fish. Maybe a length relationship. So a 1" fly to a 20" fish might be one thing at a 1/20 ratio, but what about a 2" fly to a 60" fish at a 1/30 ratio? Would that be considered?

First fish I ever caught on a fly rod was a 22" San Juan rainbow on a #22 zebra midge. I also got a 21" Yakima RB on a # 2o dropper under a Chubby Chernobyl.

That first San Juan fish was a hell of a way to begin fly fishing for me. How could I not be addicted after that? Credit to some bery generous guides on their day off that saw me and took enough pity to help me out.

When I read the title of this thread I immediately thought of the San Juan. Lots of giant fish lurking around sipping tiny flies in that river. I had one break me off on that river that probably would have been the biggest trout I'd ever caught, and had another bruiser try to eat a smaller fish I had on.

I thought fish like that only rose to flies that imitated bacon double cheeseburgers as that's what a fish like that has to be eating.

You used to lurk around the Rio Chama too, right? Damn, some of the browns in that place. Yikes

Large Summer steelhead (40+ inches) on a size 8 wet fly. It also tried to eat a size 4 and a size 6 wet. I suspect it would have tried to eat anything.

A 32# fall chinook on a #8 krill pattern.

This was from an experimental trip using intermediate lines targeting chinook and coho staging in tidewater of a lower CR trib. Wasn't really expecting to catch anything but got tired of waiting for the fall rains. So we decided to try some still-water techniques normally used for steelhead in the CR Gorge, trib-mouth fisheries.

This was also a meat trip from pre camera-phone days (for me), hence the super-classy lawn shot. The fly is barely visible in stuck in the cork handle.

I rarely have a camera with me. I'm not a photo guy.
