Bass in Ray Roberts like rocks! Moving baits, square bills, top waters, very early and then move to plastics fished slow when it gets hot. Green pumpkin and watermelon red are my best colors out there, others will have different opinions I am sure. The dam is an easy place to start bay paralleling it with a top water or crank bait as well as any of the other rocky main lake points on the lower end of the lake.
The sand bass are crazy right now from the main point between the two lake halves for a good long ways up the West half of the lake. Look for all the boats then start graphing the area and you will see why, huge bait balls and packs of sand bass chasing them. Those things can make for big fun on lite tackle especially for a kid.
Like others have said look at a map and be careful if you go up in the trees, you don't want more repairs after you just got the boat out of the shop. Lots of trees, old fence posts, and H braces that are hard on boats.
Enjoy the lake and catch a bunch!
See you on the lake and have a great day!
