I’m not sure how far your looking to travel, but we have a ton of great tailwaters here in the southeast. Once you get down around KY, you’ll start seeing some big lakes on your maps, and most of the larger lakes have a great tailwater running out of them.
TN is loaded with fantastic tailwaters, and there are a few good ones in GA and NC as well.
Like I said, not sure of your travel allowance but you might consider the southeast, as our weather will get nice here in a few weeks and it will seem like spring well before spring actually hits.
