There are several YouTube authors with good fly fishing information.
One of my favorites is Oliver Edwards. He is British so some of the info is not directly applicable. I still like ro watch them. His fly tying is quite good as well.
I live in Florida, so there isn't any trout fishing other than Speckled Trout - a saltwater fish. Bluegill and Bass are the usual targets in freshwater here.
Jim Misiura has some good fly tying videos. Tightlinevideo is another good fly tying channel.
Good luck. Have fun. Be safe.
