When you think of Great Bear Lake and fishing for lake trout, fly fishing probably isn't the first thing that comes to mind. Trolling with spoons, flatfish, or jigging deep structure is what you would normally expect to target Lakers with. Trolling is so popular because these fish are so curious and love to follow a lure for great distances and it can be a challenge to cast a fly and entice a strike within casting distance. Starting last season I had a week dedicated to just fly fishing and ended up combining trolling technique with fly gear; as well as lining up drifts across points and reefs that you could cast to and pull Lakers off at will. This season I got three whole weeks of fly fishing in on the Bear and wow was it incredible. A few things I noticed and observed in general about the lake is how sensitive these fish are to temperature, pressure, and how tightly they hold to structure. Keeping this in mind we also caught fish in water temperatures so low that it would make you shake your head and say to yourself what is this fish doing all the way out here.
As the season progresses you see a gradual shift or using this season as an example a very quick shift of fish moving from the shallow bays where the water is warmer at the beginning of the season during ice out, to being spread out throughout the lake, and then finally migrating back to the reefs at the end of the season in preparation for the spawning period. For fly fishing I want to target these fish preferably when they're in shallow water and I can work the structure they are holding on. If it's more in the middle of the season when the fish typically spread out, you have to hunt for them. I took notes on nearly every fish I caught this season pertaining to depth, water temperature, weather, barometer reading, technique used, and species caught. After looking at this shambled mess of data I collected, I started to see a general pattern but the most important piece of info I collected was at the end of the day. These fish and just the lake in general are extremely unpredictable. Moving from place to place quickly and efficiently is something I found very successful this season. That's not to say however that if you don't catch fish in the first five minutes that they aren't there, everything in moderation. Commit to the spot you're fishing and work it thoroughly, every piece of water has information you can gather from it to make your day better. With the right info regarding technique we needed the right gear.
My setup was a 9ft. 10wt. BVK series from temple fork with a large arbor BVK reel holding a full sink line running a 20lb leader straight from fly line to fly. The reason for only a 20lb leader is that most fly lines aren't much heavier than that, typically between 20-30lb breaking strain. The crucial piece of gear here is the rod, it's absolutely necessary to have a stiff enough rod to control these fish as you fight them rather than the other way around. I had a guest this season use an 11wt. Orvis and just the average Laker bent that thing in half when they dive for the bottom. I can't even exaggerate how well these fish fight on the fly; it truly is a treat when they go on a run. A good tip to remember when fighting these fish especially that trophy you are after is to keep them off the surface! Unless you are going in to net the fish if they come up and are not ready, they go into the dreaded death roll and pop the fly out! Feed them line while keeping tension, allow them to stay down so they don't feel the need to roll and also allows you to keep a good vertical angle on the fly and keep the fish hooked.
