Big Branch - duck hunting?

I've got a good bit of experience in there out of a kayak. Very doable.

Hiking in doesn't give you many options, unless you're talking about kayaking to a point on the beach and then walking in. But strictly walking from lake road, you won't have much luck.

There are definitely spots that you will sink, but most of it is pretty walkable. Just watch those ponds, there are some deep arse holes.

I'd get out there EARLY as you will be competing with other kayakers/piroguers for easy to access spots.

If there isn't much cold weather then I would limit your walking because if the grass hasn't died off, it's almost impossible to walk through a lot of it. You will sweat your arse off and your legs will be on fire because you can't just trudge through it, you have to bring you legs up over the grass.

Bring something to sit on if you can. I bring a bucket with a seat, but fill it with water because I usually sit in the water and it will tip over when you stand up to shoot.

Get as far away from the launch as possible to avoid the as many sky blasters as possible.

It can be a good time as long as you understand you probably won't limit out and you will be dog arse tired when you get home.

I haven't hunted the Fritche side of Big Branch the past 5 years but did hunt it a lot in college and before I had a boat. I got a few limits over the years out there but I would get 2-3 every hunt. It's going to be mostly divers but teal and big ducks show up randomly.
The more you go and try different areas the better you'll do. I was never stopped by green jeans and have had my decoys shot at out.
