As Victoria Lock is in Northern Ireland, I am unable to provide an OSI map showing the layout: my OSI licence and the OSI website seem to cover the Newry area on the ~1840 map but not the ~1900 that would (I presume) show the Victoria Lock at Upper Fathom.
However, there is a superb aerial (satellite?) photo on the Google Maps site; all going well, the embedded link below should show it, and you can zoom in and out as you wish.
This first page about the lock covers some of the provision for ship-handling.
For convenience, I’m going to pretend that the lock is aligned north-south, with the upper gates at the northern end and the lower at the south. The canal runs along the western side of the lough, so the west side of the lock is the landward side and the east side of the lock is the water side.
