I am not much into Walleye so I can not say where you could find them, I have heard of them west of Wichita in Cheney but not to populated, as for the maps I have seen very few that covered any of the lakes in Ks. and it has been some time now since I had seen those.

Here in Wichita there is a place called Ziners on south Washington just south of 54/400, (bussiness distric flyover)
