Roughy 75% of the time, I'm fishing a two man spread of four rods so I'll give you what usually works for me. It's just much faster and easier to bottom fish and you can generally catch the exact same species bottom fishing as you could float fishing.It sounds like you already have a really good feel for things after just one year. You could theoretically float fish in this lake, but honestly? Float fishing has taken a back set to bottom fishing on almost all lakes. It hooks the fish automatically this way and is much easier than trying to manually hook it with the bottom rod, which is possible too but much more difficult as it requires weird timing. Only pull the bottom rod out of the water when you see the line start to move and the bite alarm/bells start to go crazy. Hopefully you're high enough level to get one with a bite alarm. If you are not high enough level to afford a two-rod stand, just stick with the simple one-rod stand. If you really want to go all out, pick up a second bottom rod and fish with it on the rod stand at the same time as the other rod and your lures. If you are a pure F2P player (which I respect), you will have to simply fish as much as you can to maximize profits. Premium access account for $10 a month also nets you +50% experience and cash from every fish, so that is also something to consider. They're one of the better investments in the game with the exception of the very high level lakes, and I feel like if you really like a game, you should support the developers with a little cash flow anyways. You could also potentially buy unlimited licenses for real money. Obviously you'll never get anywhere if you buy a license and don't fish as much as you can while the license is up.

You will struggle to make any headway at first, since the cost of license and travel to Alberta is relatively high, but you should be able to overcome it if you play a decent amount and fill your keepnet. Obviously larger keepnets and stringers equal more money per day, equaling more profit for you. A 90KG fishnet should be plenty to cover the cost of staying there daily and should be able to cover travel and license costs after a few days of full keepnets.

You'll want a rod stand too, if possible, because you're going to spin fish while you bottom fish for maximum efficiency.
