that sounds way too complicated. most...no...all puddle ducks like to feed in shallow water. just set up your dekes near some ground and cover, then hunt them from the dry ground in the cover. you need some hip boots or waders.
That's my usual strategy, but I hunt a shallow marsh that's thick rice, and if you can find an open spot, you'll get ducks. The bottom's all thick mud, so just sitting isn't an option because you'll sink.
