I remember many years ago in Milton on the Mud River. One of my uncles brought in to Grandma a lovely rocking chair that he'd seen floating down the rain swollen river. He'd thrown out a long rope with a hook on it and drug it in. I think they got a lot of things that way, from the chair to a little chicken coop, with chickens sitting on its roof.
Sure hope that you are above flood level, with this weather you never can tell just how much higher it will come than it did in the past.
