Mississippi Lock and Dam #22 near Saverton, MO

From John's photo we can determine that it was built with a mix of roller and Tainter gates and a fixed wier.

The gates are not all the way open, but it looks like the lower pool level is quite close to the upper pool level.

The towboat Jonathan Erickson southbound at Lock and Dam 22 Saverton Missouri. Very windy day you can see the flags at the Lock which gave the drone some problems. I had a loss of signal at the end of the video is why it was cut short. Still had control but lost the video feed which will freak you out. Good thing it was in sight still. The tug Sir Randy J was helping to get him on the long wall.

About 1987 I was working as Relief Captain on the Bill Gee, a 2800 retractable pilothouse Nashville Bridge boat. While I was home on my time off I got a call to go to Lock 22. The Bill Gee had lost its N/B first cut of 2 single skin gasoline barges and 3 jumbo hopper coal barges over the dam. The Mate and a deckhand rode the barges onto the dam and were able, with the help of the lock people, to safely climb onto the dam. The single skin barges had ruptured and were leaking gasoline. There were a bunch of local, state, and federal agencies there monitoring the recovery. We faced the Bill Gee up to the Ruth D Jones and since we had stern bitts and a capstan, Tom Dupriest on the Jones down streamed us onto the barges while I used only the rudders to keep us straight into the current. Flipper Catlin, Terry Poole, our Captain and mate worked at catching lines over the stern. The coal barges came off easily, the 295 X 54 gasoline barges not so much. It was pretty sketchy. I had the pilothouse doors open and was wearing a life jacket in case things went bad. We put all of the unnecessary crew off on the lock wall and away we went.

[The comments confirm that that line boat has a retractable pilothouse.]

I didn't realize that some of the locks have a rather fancy building until I saw this photo. I can see the building in the background of the above photo.

USACE, Rock Island District posted five photos with the comment: "Recently, the Rock Island District Structures Maintenance Crew utilized the Quad Cities Heavy Lift Crane to pull the first Trunnion pin in the Tainter Gate replacement project at Lock and Dam 22. Weighing in at 5,000 pounds and being in position for over 80 years, the pin proved difficult to move, but with the assistance of the crew, the crane, some heat and a hydraulic ram, the task was completed."

USACE, Rock Island District posted five photos with the comment: "Recently, the Mississippi River Structures Maintenance crew installed a new Tainter gate at Lock and Dam 22 with the assistance of the Quad Cities Heavy Lift Crane. This gate is 60’ wide x 27’ tall with a 40’ radius from the centerline of the trunnion pins to the US skin plate. The original gates that are being replaced weighed around 200,000 lbs while the new gates weigh around 210,000 lbs."

Dave Harrington: Interesting. How is the gate attached to the trunnions? Weld, rivet?
