Fly of the Month
GT Western March Brown
(Rhrithrogena)
by Greg Chester

Spring time on the Bitterroot is always an exciting time of the year. We start with the long awaited Skwala activity after winter and then are treated to Baetis, March Browns and Gray Drakes as spring sets in.  We’re fortunate in the Bitterroot to have such a diverse bug population and even more privileged to have such terrific hatches to fill the gap between Skwala’s and the summer bugs.

This unique pattern has worked well for me over the years and effectively imitates any mayfly adult by simply changing color and size. It’s tied in the style of Rich Christian’s GT Dun series that replicates both adult and emergent stages. This is made possible with the Gamakatsu C12U curved shank hook and unique tail placement. When fishing this bug keep floatant off of the abdomen and shuck – this is important to insure the emergent stage is replicated properly.

Good tying and good fishing!

BRTU Fly of the Month – Skwalla Nymph by Greg Chester

Monday, February 23rd, 2009

Spring is just around the corner and the sight of trout eagerly rising to a dry fly won’t come too soon. We saw a few sporadic rises early in February but it’s still a sub-surface, bottom bouncing presentation that draws the most strikes at the moment.

Skwalla Nymph by Greg Chester

We’re fortunate in the Bitterroot to have such a diverse bug population and even more privileged to have the Skwalla Stonefly to kick off our spring fishing. Before hitting the river most anglers wait for the bugs to surface, but if you’re really eager to get started I think you’ll be pleased with some nymph fishing until the fish start looking up, plus you’ll likely have your special spot all to yourself.

This basic pattern has worked well for me over the years and you can imitate any stonefly nymph by simply changing color and size. You may embellish it with soft hackle or rubber legs, a segmented thorax or a bead but it works quite well as shown. This pattern calls for dark olive but dark brown will likely work as well. I tie it weighted and add split shot when fishing. Work on getting a natural drift – it’s just as important when bouncing nymphs along the bottom as it is dead drifting a dry over risers.

  • Hook: Size 8 or 10 heavy wire 3XL nymph hook (Dai-Riki #710 e.g.)
  • Weight: 10 – 15 wraps of .025 diameter lead wire
  • Thread: 3/0 Dark olive Unithread
  • Tails: Black or dark brown goose biots, split
  • Abdomen: Dark olive Hare-Tron dubbing tightly wrapped in a dubbing loop
  • Ribbing: Black vinyl v-rib, medium
  • Wing case: Dark olive or dark brown Thin Skin
  • Thorax: Dark olive Hare-Tron dubbing picked out on sides & trimmed flat on bottom
  • Head: Tying thread

Good tying and good fishing!
