Turkeys love to roost over water. The famous Alabama turkey hunter Ben Lee said that a turkey always feels safe if he can hear his droppingssplash thewater underneath him.

I prefer to hunt around ground you describe, swampy low ground. This is typically the first thing to green up in early spring because it's wet. They can find snails, slugs, and other critters to eat. Fresh buds and bugs are always attractive to turkeys. Creek bottoms are also out of the wind and turkeys will congregate there on windy days.

Turkeys will wade streams, standing water, and mud. I've personally watched them wade standing water up to their knee joint. They go where they want to go without any problems.
