This is one of those topics where the more I researched it, the more I got confused because the sources contradict each other.

This is obviously an enlarged lock because it has two chambers and the southern chamber has been lengthened.

This source puts the lock a little further west of the above satellite location near today's Stubborn Girl Farm.

And this source indicates that there were locks in both locations.

1898/1954 Canajoharie Quad @ 62,500

If there were two locks here, then the one near the farm would be #33, and the one we can still see would be Lock #32.

But Lock #32 is west of Pittsford, NY.

So I conclude that the above Google map and topo map are wrong and that the one that we can see is #33.

This map resolved my confusion. The topo map shows both the original and the enlarged locks. The western lock is the original lock. And the label of "Enlarged Erie Canal Lock No. 33" on the Google Map in ErieCanal_today is incorrect. It should be labeled "original" instead of "enlarged"

Note the north wall of the extension of the south chamber.

"Only three other locks on the Enlarged Erie were lengthened at the head end owing to the amount of excavation necessary on that end." The lift is 6.031' [ErieCanal_today]
