This is the time to fish Rathbun. The lake is 11K acres normal pool so it is probably around 15K now with an additional 10' of water to spread out!!! You won't have to worry about being crowded. I have been going for many years now and will be there this coming weekend. Hoping to get into some nice slabs. I would bring along a couple of long rods (dabbling) for dropping some jigs into the brush that should now be submerged. Those females should be up in there trying to do their thing. The water temps are coming up pretty quick too. I heard that the surface is 71 today. Like perchjecker said, this could be a good spawn unless they drop the lake levels to quickly.
Good luck and maybe we will see you there (red lund grand sport)
