Well you do have the fact that sand drains well on your side. And the water doesn't look that deep around some of them... I'd bet they pull through this if the rain stays away for a couple of days. But maybe I'm just being overly optimistic today?
Thing is, the first real tropical storm/hurricane that comes along will likely flood them epically - even if they make it through this.
Take the opportunity to scout some dry grow spots now while the water is still high and mark them. You'll take something positive out of the event for your next grows at least. I even went so far as planting a few in high and dry scrub-palm hammocks this year just in case my other sites get flooded out.
*By the way, in picture 2 (on the right side) it looks like there are Frog's-bit plants (look like small water-lilies) all over. They may also be water hyacinth - can't tell. Those are mainly aquatic plants - so if you see them in the future it means that where they are growing probably floods often. Oh and also, if you look at the base of any trees in the area (like in the fourth picture), you'll notice they are abnormally fatter than they should be at the base of the trunk. That enlargement of the trunk base is a sign that the trees spend quite a lot of time sitting in flood water. Just a couple of things to help you pick better grow spots in the future. Hope it helps.
