Confusions About Louisiana Public Waters

[Wyoming762]

Hello. I currently live in Wyoming but am originally from Costal Texas. Ever since I've moved I've missed the Gulf and intend to eventually move back to it. I'd very muck like to make the move to Costal Louisiana, because I like coastal fishing and think swamps/bayous are amazing ecosystems and would love to spend lots of time there. Navigating bayous and backwaters in my Jon boat with my dog on a regular basis has always been a dream of mine. However, I'm very much confused about what type of swamp you are allowed to access. I always assumed it would be somewhat similar to the way it is with rivers (if it is navigable you can often navigate it), however, with some research this obviously not the case. For instance, in the Atchafalaya Swamp I can find two large pieces that are publicly owned: the Atchafalaya NWR (federal) and the Atchafalaya Delta (state). Is everything else in the Atchafalaya Swamp privately owned and inaccessible to the public? Are there types of waters the public is necessarily allowed to access? Please help clarify things for me.

Also, if anyone would like to suggest any places of Costal Louisiana that have what I'm looking for (accessible backwaters and swamps/bayous) please feel free to do so.

Thanks in advance.
