This time of year the main lake brush piles hold lots of fish but you can still catch them dipping trees near the channels in 15 to 25 ft of water. About the time the dipping trees heats up in the creeks they close the wildlife refuge on the main lake just north of W bridge Oct 15. Have to put in at Plattsburg ramp or one of the roads up north (be aware of the duck hunters up north). You can catch them up Camp Branch side but you will catch bigger fish on the Little Platte side is my experience.
I like both trees near drop-offs and trees on the edge of flats.
