I’ve only been able to hit the creeks a couple times this year, but I’ve been developing this brownline nymph for the past couple seasons. In particular, I wanted this fly to target a specific river, but I’m finding that it has been producing a ton of resident rainbow trout on all the creeks I’ve fished. The thorax is a split thread loop wrapped like a soft hackle. This gives the fly a jacket of UV dubbing and the appearance of trapped gas. The brown body of the fly is contrasted with chartreuse ribbing and can be seen through the shroud of brown UV ice dubbing. I’ve used tungsten to help get this fly down deep and into the strike zone quickly. It’s a great little bead head fly for the small pocket water creek of the Greater Toronto Area (GTA).
