Skwala (Large Springfly) Stonefly Nymph Skwala (Large Springfly) Stonefly Nymph

Dorsal view of a Skwala (Perlodidae) (Large Springfly) Stonefly Nymph from the Yakima River in Washington

This Skwala nymph still has a couple months left to go before hatching, but it's still a good representative of its species, which was extremely abundant in my sample for a stonefly of this size. It's obvious why the Yakima is known for its Skwala hatch.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

A couple hours on the Middle Fork Snoqualmie

By Troutnut on August 3rd, 2019

I talked my wife into a quick trip to one of our home rivers on August 4th. It was the lowest I've ever fished it (around 235 CFS downstream at the gage, far less up by us), and that made for some easy wading. Some of the pools were practically still-water fishing. However, we hit a particularly good one at dusk where we caught dozens of fish without even having to move our feet. The big ones of the night were 7-8", but it's still fun.

For a species not yet reported in my state, I've been surprised to find these in two different locations lately. I was tempted to think they're the more common Paraleptophlebia debilis, but the characteristic big dorsal bump on the claspers just isn't present.
