I heard that here in Colorado If you take your boat out of a lake effected with some kinda snail you have to sterilize the bottom before they will let you leave the boat ramp area. Here, read up on it......

Same thing in some California, Idaho and Montana lakes. Mud Snail and whirling disease problems in most Western states. Idaho even checks pontoon and float tubes.... it's a big fine to not stop at checkpoints.
