Always a difficult decision with so many great patterns posted here. I checked out your location since I wasn’t familiar with your town. It’s hard to beat the old standards like Pheasant Tails or Hare’s Ear nymphs on any water. I’ve fished the Oswego area a bit years ago. I found a good deal of similarity of insect life on the streams there and mine here so I’ll suggest two spring patterns that have worked for me everywhere I’ve fished them. Both are small patterns 18-22 but catch big trout for me.
Al’s Rat and a Black Diamond Midge. Both are posted here and the tying instructions (both simple patterns) can be found on the web.
Are your trout stocked fish? If so, (and I hate to say it) mop flies in tans, olives, and grays are deadly. Final two suggestions, again both patterns posted here in the past. Try the Holy Grail and the Killer Bug patterns.
Can’t wait to see other folk’s suggestions.
Since no one else is putting in their two cents worth Drew, you better tie up some olive and some green free living Caddis larva. Lots of patterns to choose from here from works of art to simple as pie. They all work about anywhere you fish them.
Thanks so much Bill! I did some hares ear nymphs and pheasant tails so far, came out better than anticipated. I’m slowly working down your list and filling up a few rows in my box. Appreciated! @trublubug
You are welcome Drew. I was really hoping to see some other opinions for your question. I like to know what others think.
I’ve never found a fly so universally accepted by the trout as the black diamond midge. It’s not all that different than a zebra midge but for me it just out fishes that excellent pattern. I’ve had days where I’ve hooked (not all landed - it is fishing not catching after all) dozens and dozens of trout on that pattern. It works well in dark brown too. It’s one I’m NEVER without.
