I have multiple wetlands and some are in the creek flood zone. We actually had a bunch of warmouth in one of the deeper wetlands that my neighbor had a blast catching (and eating). My 4th pond has not yet filled, but it is connected to a wetland of similar size to the pond, but neither is in the creek flood zone. The area that I was planning to make the next wetland is quite small, so even a pond of sufficient depth to avoid winter kill might be a challenge. I actually have 2 more wetlands planned within the creek flood zone, but one would be a challenge to make deep due to water coming in, even in a drought. We are blessed with a place that is great for making water features. Nice to think about future projects when its cold outside!
