I think a combination of those things. Barges are loaded heavier than they used to be. Outdrafts are wicked, and did not exist with the old wicket-type dams, which were lowered and tows ran over them during high water. There was more “tie up and wait” in the olden days, now it’s go, go, go, all the time. Pilots not as familiar with the areas they’re running — the office (and many pilots) think they can go anywhere, and the mindset among many on the boats is that the Ohio is a “retirement river”, where it’s as easy as it gets.
