check your PM's, I sent you one about Falls Lake. Not all the impoundments require a permit, several are open to all hunters all season - but of course that leads to more crowded conditions. Pay attention to the regs - you can't hunt ducks every day on every lake and some require you to stop hunting by 1pm. You have to check the specific regulations for each game land in the "game lands" section of the regs digest.
One thing that I'm not sure was mentioned is that on both Falls Lake and Jordan Lake the NCWRC rotates the flooding of impoundments from year to year. Some of these are "green tree" impoundments which means they want to keep the trees alive (green) so they only flood them for part of the year and some years they don't flood them at all. I haven't checked this year's game lands book yet, but in the past, they've printed the flooding schedule in the game lands book. One additional source of excellent information about current conditions is to speak with the NCWRC folks based in the Butner Depot. These are the guys who run the pumps, plow the fields. Their number is 919-620-0089.
Boats are great, but I tend to agree with Mr. Taxidermist that a canoe is also a useful craft for Falls. I'm talking about the headwaters, up into coves, and up into feeder creeks for jump shooting. I've explored a bunch of them in my 16' canoe, but still have a lot to check out!
Maybe the best way is to buy that bigger boat then make friends with a person who owns a canoe? :-)
