"The maximum lift is 10.5 feet with an average lift of 5.3 feet....The movable dam has three non-submersible roller
gates (20 feet high by 60 feet long), 34 non-submersible
Tainter gates (20 feet high by 40 feet long), and six
submersible Tainter gates (20 feet high by 40 feet long).
The submersible Tainter gates submerge three feet." [

In the only other comparable view available, we can't see the river level.
And then it occured to me that I could get a different view to compare the river levels.
Judging by the height and maintenance of the levees behind the tracks, there are times when those tracks are under water. According to the 2004 SPV Map, those are CB&Q tracks that are now used by BNSF and NS.
The gates were also out of water in 2008, but the river level wasn't nearly as high on the lock walls.
