If you are talking about bay natchez you can launch at the old white castle landing. If you stay on La 1 heading towards W.C. right before you get into town take a right onto La.993 and go 5 1/2 miles down 993 til there's a large turn to the right and you are there. W/C Canal & Landing
You can put in at the store by the pigeon bridge. Go south and you will see a small bayou to the left in a curve of grand river. Go in the smaller bayou this will bring you to bay natchez. You will enter the lake in the south part. Hope this helps.
