Here are the 2 landings - Davis Landing is what we always used just because we always fished on that end. It may not be open though. That is the son of our former Governor Jimmy Davis who wrote 'You Are My Sunshine'. His son doesn't have many accomplishments but I will not go there.
The other is the store, its not too far off track
The other pic is the chute that runs out the lake into the MS River, its a cool ride thru there, but go slow there is always a big tree down, its a good place to get in the shade and just tightline for catfish in the middle of the day if you don't want to go out into the MS and fish at the rocks there. Palmyra is about 7 or 8 miles north once you get in the MS River. Palmyra is just the waterway that makes Davis Island an island, cool to explore in there too and if you find a treetop down out the current it might be worth trying
The camps are just south of the landing, the docks will be underwater probably but they come WAY out, and if you can find them you can catch crappie there but you will not be the only one there. Where I labeled 'willows' will be good from 19-15 feet, they are small willows that are probably just under the water right now and you will get hung up in there but its got some big fish in there. The large willows near there will have slack water and always amazed me how many gar were in there, but never caught any crappie in there.
The river is at 19 in Vicksburg right now and as long as it does not get below 13 you can get out easily into the river as long as there isn't a log jam and if you even care to get out there, the lake is plenty big enough to explore all day.
The willows opposite the landing can be good you just have to find one that is falling in the water and sometimes you can sit on just one and pull out numerous fish. Also, they may still be spawning so don't be afraid to fish real shallow up in the woods.
I may just have to go up there myself next weekend now! I need some Yucatan in my life, but dang that place is 2 hours from Monroe and MUCH farther from Youngsville!
