Early Season Skwalas On Montana's Bitterroot

“At any given access site you might find license plates from Nevada, Washington, Oregon, Wyoming and beyond. There’s good reason for that activity — the skwala hatch is the season’s first emergence of big bugs and the trout, accordingly, pack their stomachs with skwala nymphs and winged adults.” Greg Thomas describes last week’s trip to western Montana’s Bitterroot Valley to catch the skwala stonefly action as early-season bliss.
