All good advice above the whole lake dosen't turn on at the same time plus sometimes one arm or another will muddy up do to heavy rains so be prepared to move to where the fishing is the best. Any kind of crappie bait will catch fish I've seen people throwing everything everything in the book at them and catching fish, makes you wonder sometimes. If it gets real muddy and probably will, does every spring, a 1/16 oz. Roadrunner with a black@chartueuse plastic tube works great along with black@pink couple of my favorites anything with chartueuse on it will catch fish along with a bright orange head. I use a lot of 2" and 3" baits also.
Don't mean to scare you but Truman is full of stumps just under the water millions of them, get a good lake map "HOT SPOTS" is as good as any and learn where the channel is. A depth finder helps and anytime you turn off the channel to go into a good looking area just slow down and be carefull and you'll be fine. One thing about Truman you don't have to run a long way to find fish, there's ramps all over the lake and you can put in close to where ever you want to fish. Good luck and when you get close to going post again and I'm sure that someone will be happy to help you.
Something else I just thought about but I have seen a lot of people turkey hunt out of the boat. There's lots of public land all around Truman, they'll be in their camo gear fishing and hear a gooble beach the boat and hunt turkey for a while then come back and fish some more. You can't shoot out of the boat but you can beach it and get out and hunt the public land.
