Hi Tucker, first off, A big thanks for your service to this great country, Without you guys and gals serving, things may be different and there wont be any fishing or hunting or any other freedom we enjoy.
Next, I'm no expert, but will share what I know about summer fishing on Truman. There are many ways to catch them, some like to tie up along the bluffs or deep standing timber and dunk minnows. Others like myself, like to move around and use a 10 foot dipping rod, and look for likely targets on the main lake flats, or channel edges, or brush piles.
I like to fish generally 10 foot down. I like fishing hedge, or ceder trees, and pole trees. You can find fish very shallow in the summers as well. Best advise, go fishing, when you catch fish, go look for duplicate structure elsewhere on the lake in similar depth of water. I like to find out of the way stuff that is isolated. Best of luck!
Most of my money is spent on fishing, fishing tackle and boats, the rest is wasted.
