Little Mud River has some shallow spots in the ICW channel. Our track was established by the suggested deepest water shown on the Navionics Sonar Charts. We steered the boat according to the deepest water seen on the Navionics chart. Our course slalomed back and forth as we followed the suggested deeper water. In the end, we found nothing less than 5’3” along our track. A track right down the center or 30 feet either side of our track might have seen different and shallower water depth. My best guess is that a track straight down the middle would see shallower depths there are probably some places with less than 5 feet MLLW between R194 and R192.
