Winter is here guys!! The days in Alaska are getting shorter and much, much colder! Frozen waders and rod guides, cold fingers and toes, frozen flies…the list goes on. Honestly though, when a big rainbow is on the end of your line, all those obstacles seem completely irrelevant.
Fishing in Alaska is pretty dang awesome during any season, but there’s just something so special about fly fishing for rainbows in the midst of the colder months. I’ve lived in Alaska my whole life, and I’ve always LOVED winter. So, when winter is here, I don’t want to miss a second of it.
Fishing in extreme cold definitely has its pros and cons. The coldest I’ve fished on the river, I started the day at -8 degrees, and the high for the day was 5 degrees! I do a lot of ice fishing as well, and the coldest day I’ve had was -25 degrees! You will NOT find me on the river in temps as low as that!
Of all the species of fish, I don’t think I could choose a favorite to target. I want to say I favor rainbow fishing in the winter just a little because it’s so different from everything else I do throughout the year. It’s definitely more of a challenge, which also makes it more rewarding.
This time of year, the water has dropped a ton (hopefully), and the fish are in different areas. Once that water drops, rainbows like the deeper trenches, but keep in mind you need good current to drift or swing through.
Winter in Alaska (and a lot of places) can have some pretty significant swings in temperatures. Here, it can be 20 degrees one day, and then in the single digits the next. Keep in mind that trout need to adapt to that intense temperate change before they turn back on.
Rainbows, especially on the Kenai River, never go hungry. With our massive salmon population, they have more than plenty to eat. Even more so on pink salmon years! On the Kenai, pink salmon only run every other year (every even year). Super odd, but can’t complain though! That only makes the trout extra chunky! Speaking of food..
Flies & Presentation
In the winter, the trout rely on mostly flesh and eggs. The silvers are the last of the salmon to enter the river, which means they’re still lingering around and waiting to spawn late fall/early winter. The egg drop/bead bite is unreal this time of year.
Silver eggs are 8mm in size, so throughout the fall and winter, using this size painted bead is pretty successful. 10mm’s are a good choice when the water is dirty. I like to use my own paint on top of the painted beads to make my own special colors! This gives the bead more of a realistic look and will make it stand out compared to the ones they see regularly.
Now, my favorite topic – swinging flies! The majority of my time winter fly fishing consists of swinging flies. My favorite flies for rainbows are different leech variations, intruders, and sculpins! I prefer this method of fishing because of the precise control you have over your fly presentation and the art form that comes with casting. Also, you get to feel the fish take, instead of watching your indicator go under.
Rods, Reels, Line/Leader Setups & More!
Sink tips are a key factor with swinging flies. You have to have the right amount of length and weight for that specific day. Alaska has some weird weather, so the water levels are constantly changing.
If your sink tip is too light, you’ll be fishing too high up in the water column, and the swing will be too fast. If you’re fishing heavy, your fly will be dredging bottom and swinging too slow.
Rod weight matters too! If your rod is too light, you won’t be able to throw heavier sink tips effectively. For medium-large flies, I recommend at least a 7wt rod.
The 7wt Axiom II Switch casts light and heavy sink tips effortlessly. Hands down, my favorite rod for swinging flies. You also need a reel that won’t give up on you as it’s almost completely frozen, and a rainbow decides to make a big run. I trust the Power Reels with all my heart!
As for my single-hand set up, I am currently using the Axiom II-X in a 6wt, paired with the BVD-SD Reel. The impressive back bone and power in this rod truly makes a difference when casting on freezing cold days, and through winds.
I hope you guys enjoyed learning some of my winter rainbow fishing methods. I could seriously talk about it forever, but I think I covered some basics for now. Wishing all of you good luck on your winter fishing adventures this season! And if you don’t like winter, you’re missin’ out.
