It looks like you would have to have a WV license because not only would you be standing on WV land, but WV also owns most of the Ohio river. Per the WVDNR, if you have an Ohio license they will let you fish the Ohio from WV but it doesn't say anything about Kentucky. I'd play it safe and get a temporary license if you don't want to pay full price for one. It would probably be cheaper than a fine if you got caught.
