This is Lock #3 of the Welland Canal.
At first, I thought the following photo was of Lock #1 because it has that canal next to the lock. But I could not find a skyway downstream from that lock. While looking for this lock, I discovered that locks 1-3 have the same basic design, which makes sense.

This lock also has a museum.

This diagram shows that Lock #3 is close to the base of the Niagara Escarpment.
This view shows that the lift of the lock is higher than the canal depth. In fact, the ship draft is 27' (8.2m), the depth over the sill is 30' (9.1m) and the lift of this lock is 46' (14m). [Dennis DeBruler]

The 46' (14m) lift is high enough that the decks of the ships are below the top of the lock when they are at the lower pool level.

I wonder what kind of stresses the propwash puts on the gates.

Fresh from Lock 3, Welland Canal.
[This is probably the 400' USS Minneapolis-Saint Paul. It was commissioned in Duluth on May 21, 2022.
"The “Littoral Combat Ship” was built by Lockheed Martin and Fincantieri Marinette Marine in Marinette, Wis. With a shallow draft, it is designed to operate in waters out to 25 miles from shore. The ship isn’t powered by a traditional propeller, but instead uses water jets — huge versions of those found on jet skis. Electronics maintenance officer Joseph Varello said they allow the vessel to slow down, and accelerate, faster than any other Navy ship. “Think of an Olympic sized swimming pool,” explained Cmdr. White. “And think of moving that volume of water every second through our propulsion system. So that is how much thrust vector that we generate.” The ship was originally scheduled to be commissioned in Duluth last spring, about a year after it was christened and launched in June, 2019. But it was delayed to fix a flaw in its propulsion system." [mprnews]]
