Some of you guys should try reading Kansas law before commenting on it.

From the 2013 Fishing Regulations pg.6 "Unless otherwise posted, all streams in Kansas other than the Arkansas, Missouri, and Kansas rivers are under private ownership of adjoining landowners. Those three large rivers are public up to the normal high-water line."

From the 2013 Hunting Regulations pg.5 "Landowner permission should be obtained before pursuing wounded game onto private property. If you cannot find the landowner or get permission, contact your local natural resource officer."

So not only is it legal to hunt deer in the three stated river bottoms, if you wound one you have legal options to retrieve it.
