Jacob,
Good luck in the tournament. I'm heading down this weekend for the first time in 3+ months and we'll see how much I think I know of the lake 😊. Not really targeting any species as I'm just ready to catch something. you can get some water temp info if you search this. Bull Shoals Lake Water Temperature & Lake Level - AnglerSpy™
You can also look on youtube for some bull shoals video reports. Del Colvin just put something out a couple days ago that should help you get you started.
I generally try to get down around this time every year. Some trips are good and some not so good. I'm thinking that this is shaping up to be one of the better ones but I always think this before the trip LOL! Have fun and enjoy! It is a beautiful lake.
