|A skwala dry separated the men from the boys on the Gallatin R.|
I lengthened my leader, tied on a Gould's half down skwala, tied on another length of tippet and finally knotted on a March brown sparkle dun, size 14. That's four knots! And through all of this I was fighting the distraction brought on by the fact that the trout had finally realized that there were large mayflies all over the surface; breaking my concentration with every splashy rise.
The fishing was amazing for about two hours, until the March brown emergence petered out. I took a dozen or more fish on the sparkle dun, and two on the skwala. You may wonder how two fish validated my infatuation with the skwala hatch? It's simple, size. The fish that I found up and rising to March browns were of modest proportions, generally 10- to 14-inches. The fish that took the stonefly stretched to 17-18 inches, large fish by Gallatin River standards. Validation.
