So two 11 year old boys, absolutely get minnows - get the smaller minnows, not the ones that feel like you already have a fish on the line.... I would get some 1/8 oz, chartreuse jigheads to rig them on(through the lips). Last post is correct, brushpiles are holding mostly small fish, most of your big fish are still hanging on the docks. However you have to shoot them(docks, not the fish) to get to the fish, and that may not be good for the boys. There's lots of brush along the dam in 10-14ftw that has fish, and then the big main lake point straight across from the marina has fish. Look for piles around the point in 10-15ftw, fish will be holding at the top of the structure. Good luck!
