Oops, your aim was a little off on that post Pete.
A good friend worked the coal barges on the river system in Alabama
for years and has related some stories to me over the years.
Besides the locks there are also railroad bridges to clear under, and highway bridges of course but they are usually tall. The rail bridges have to be lifted but with your clearance some will not. The Army Corps of Engineers have free e-charts for the river system now.
Only about four or five locks to get to the Mississippi
line (that's as far as I'm going sometime soon) but then in MS there are many locks to get into Tennessee because of elevation change. Don't know much about the rest.
The coal barges are HUGE and want the entire river to maneuver in the bends. Pushed from the rear they swing around at the back and care must be taken not to be in a squeeze play with the river bank. Many bends are 180's and it's best not to be there with a barge. Communicating with the barges will help.
I know you will be working but it sure is a great place to be floating along.
edit,.... good point about he flow right now. There is a website with real time updates I'll look for.
Some of the locks and dams are only a few feet high in Alabama
. When the flow over the dam is great enough the barges simply bypass the lock going downriver and simply steam directly over the dam since the water
is over them. Sounds crazy but they do it.
Once the flow was so great my friends float was full reverse at full power and still going down river. They had to put it into the bank and knock down an acre of trees to stop.
