As always being very wet.
|The swamp is in constant|
But except for a few deep spots, surface water in the swamp is shallow. For portions of the year there can be little or no water at all. Compare that to a deep lake up north where you can walk around the bank.
When the swamp gets really wet, it has no banks at all (despite still being shallow.)
Did I mention the swamp has a Deep Lake?
It's deeper than Lake Okeechobee.
Five times deeper.
