KDWP website would be a better resource for this type of info, but IMHO...
Crappie fishing is good in Kansas wherever there is water, which is mostly the eastern 1/3 of the state. Bird hunting is best in the western 2/3 of the state. That's not to say there aren't exceptions to the rule, but generally speaking...
I don't think you can stick a pin in a map and say, "this spot is both the best bird hunting and crappie fishing spot in Kansas". If I had to pick a place that would be the best compromise, I would say the Glen Elder area.
I am just pullin' your leg.:D
