The upper Teton, up in the valley under the back side of the Tetons, is a spring-fed meadow river — slow, weedy, clear, and technical, with native Yellowstone cutthroat and rainbows that tip up to mayflies and refuse anything clumsy.

About this water

The upper Teton, up in the valley under the back side of the Tetons, is a spring-fed meadow river — slow, weedy, clear, and technical, with native Yellowstone cutthroat and rainbows that tip up to mayflies and refuse anything clumsy. It's quiet, gorgeous water that asks for a careful approach and a long leader. Below the valley the river drops into a canyon and turns into a different, brawnier animal. The green drake hatch up top is the event people plan around, and it's worth planning around.
