Yes. Grow there. Pick a relatively high spot, like on the edge of the marshy area or on an island or hummock. You want your plants above the water line, but close enough to it that the roots can easily get down to the water table. With a little luck, you won't have to water all year, which makes it a lot easier to keep a low profile.
The best thing to do this time of year, when the water is still high, is pay close attention to the vegetation. If you know the woods, this is easy, but if you're not an outdoors person you'll have to teach yourself how to tell the difference between plants that grow in the water and plants that grow on dry ground. It's not that hard if you use your head, and once you figure out which are which, you can use that to tell where the marsh ends and the dry land begins once the spring highwater season is over. Plant above the water line, and you should be fine.
One word of caution - high marsh grass leaves a pretty distinct trail when you beat a path through it, and it can be visible from the air. And last a very long tome - days, weeks, even months. If there are trees in the area, try to stay in them as much as possible, and just make short paths out to your plants to whatever extent you're able to do that. The longer the path you leave, the easier it is to spot from a chopper; it's the length that makes it noticeable.
