Jackson Lake, WY fishing report
Jackson Lake sits at roughly 6,800 feet in the shadow of the Tetons, and the fishery here is dominated by lake trout, brown trout, and cutthroat trout year-round, with cutthroat most active during spring and fall when water temps stay cold and they push toward inlets like the Snake River arm. I should be straight with you: Jackson Lake is not bass, walleye, pickerel, catfish, or panfish water — those species are not established here, and chasing them would be a wasted trip. What you do have is world-class coldwater fishing, with lake trout running deep through summer and cutthroat and browns hunting the shallows during shoulder seasons.
Work the inlet flows early and late season when cutthroat stack up chasing spawning smelt and feeding on current-driven insects — streamers and spoons in natural colors produce well here. During summer, lake trout drop to 60 to 100-plus feet over deep structure; vertical jigging with tube jigs, swimbaits, or heavy spoons near submerged points is your best play. Watch your fish finder for thermocline depth, typically where cold water pools below 50 to 55 degrees, and target rocky points where that cold layer meets structure. Browns favor low-light windows near shoreline drop-offs throughout fall.
