I'm not a big lake fisherman myself, but Sardis Lake and Broken Bow Reservioir (Beavers Bend state park) are supposed to be great as soon as water temp gets rightwhich may be delayed with the snow and cold rains we have been getting (I'm in AR, but just a few miles from SE OK). Broken Bow is known well for brownies, Sardis for the crappie and large mouth. Catfish good in both, better in Sardis.
