Big lock. Any idea what the vertical lift is ?

Quimby's will list the vertical lift for each of the various locks,
and I'm sure that Quimby's gets their info from the Army Corp of
Engineers. And as you probably know, those figures are averages. The
lift will vary based on various conditions apparently. We guessed
that we were raised about 45' on this one. I don't think any of us
checked the Quimby's to see what the official lift is.

According to Wikipedia max lift is 75 ft:

That's a very big lock, about to get even bigger according to the
write up. We were in a 65 foot lock on the Ottawa River once and that
was a monster.

The lock in the picture in your link looks a bit unusual. It's not
like the common Mississippi River lock. All of the locks on the
Mississippi vary a bit in overall character. But most share the same
mechanical dynamics. A few are a bit different, like the lock just
below Alton, Illinois. We went through about 22 locks going down
river, with the steepest drop being lock 19, if I remember correctly,
at a hydroelectric plant. That dropped about 30 feet. Considering
all of the barges we saw waiting for passage through the Kentucky Lake
Dam lock, it doesn't surprise me that another lock is slated for
construction there. There were no signs of construction having
started, though, when we went through, from what I saw. I have a
video of the approach to the lock that I'll eventually get on Youtube.
