Green River? First lake? Deuxieme-sault?

Hello everyone, My brother, nephew and I are about to go on a fishing trip up to Green River, First lake, and Deuxieme-sault. I've never been there, it looks promising, I'm just wondering what to expect, according to the 2022 regulations it doesn't appear to be Fly fishing only, just wondering if anyone can give me some personal experience from there, Thanks
