Alright. Is there a strong current on the river? I have a 12ft inflatable boat with a 30lb Minn Kota motor. Will that be enough?
Unfortunately 'NO'. I hunt the Nisqually often and for over 25 years now. Mostly out of my canoe but also with a couple buddies with duck boats.
With currents and tides, that trolling motor isn't going to be enough plus it'll fun a battery dead in a hurry going no place on big tide change days. A row boat, canoe, kayak or motorized boat are much better. It's a large area that takes some time to learn because of the different water levels etc.
PM me and we'll do some more bs'n.
