Chimehuin River

The Chimehuin River is a classic big freestone river with brown trout large enough to deserve the shaded deep willow lined banks. The Chimehuin is similar to the Madison River with true pools and runs. In places the river braids into a maze of willow lined channels with the feel of small water and the ever present possibility of big fish.

Average rainbows and browns range between 15-20 inches with good numbers of fish up to 24 inches and some well beyond. Every year a few fall browns in the 10 lbs range are landed on the Chimehuin River.

All methods of fishing can be effective- prospecting with streamers, nymphs, and large attractor dry flies, spot fishing, or matching the sometimes prolific hatches.

Hatches on the Chimehuin River

  • The caddis kick off the hatches in early December, peaking later in the month and through early January. They typically run through January with scattered cahill mayflies with the hatches tailing off in early February.
  • During this same timeframe a large size 8 & 10 yellow drake hatches most evenings and can bring out some big browns.
  • Afternoon terrestrial fishing is effective throughout the summer with the best time falling between late January through early March.
  • With the cooler temp of the fall, the mayfly hatches start up again with mahoganies, a speckled winged grey, and BWOs keeping the fish tuned to the surface.
  • Streamer fishing is effected on the larger fish throughout the season with the spring and fall the best timeframes for stripping for big browns.

I didn't think an experience like this was possible.

This trip, was, for me at least not just a trip, for me it was a real adventure, a real experience. I love the wilderness and this trip afforded me the opportunity to connect with the Alaskan wilderness in ways very few people do. It was an experience I will never forgot in a place I can’t wait to get back to.

The outfitter handled everything perfectly.

We were thankful that Outdoors International hooked us up with a great outfitter because they were able to find us an acceptable alternate on short notice. Overall the two year process to get this float in was seamless and worry free. Just like it should be.

Thank you, Stan Masneri

What an amazing experience!

The lodge was out of this world! Our rooms, the delicious food, the incredible wildlife and the scenery were amazing. Our photo safari guide was truly exceptional and had us on animals almost constantly. We saw over 30 different species and had some incredible up close experiences. Africa is amazing!
