Hey all,
First time poster, thought I could add my 2 cents since I have some recent charts of Patoka.
So I'm a Fugawi software user and I have the Navionics HotMaps Premium East Charts on SD which I also got from them. From what I can see, Patoka Lake looks pretty nice with 1' contours. Not sure who surveyed them but I would say that its updated fairly regularly.
A picture's worth a thousand words so here's the screenshot for you:

P.S. I just realized, I adjusted the safety depth to 31ft in the software... Oops.
