I do not own or have access to a canoe or johnboat, is the swamp wadable?

I definitely would not recommend wading. The bottom is very unpredictable and extremely mucky in most areas.

nasty to wade not to mention the reptiles. Ed

Vatter,
I wade it all the time. Some years are better than others for wading conditions. Conditions change all season, just cause you went to a spot one week doesn't mean you can go there the next.
 Wade with a partner and if not make sure you go slow, have a sling for your gun and use a long wading stick. I like mine to be about 8' with a hook on the end. Take shots accordingly and have fun.

Waded the swamp more than I canoed it, easier in and out. Find the old duck farm, get on the old railroad bed and walk it either direction away from the truck. Shot many a woodie,teal and mallard, yes you need to be careful and use your head, go slow and like fishing coyote says, make sure you have a sling for your gun.
