This map is from 1869. It doesn't look any different to me. Are you sure you aren't thinking of Winooski, which was incorporated from Colchester in the 20's?
It's also worth mentioning that a lot of towns in that area of the template include water anyway.
Yes I noticed Winooski, I simply coloured both according to the Colchester figures. I’ll look again at the file because I recall some peculiarity around Burlington from the south and east. Could be that I miscalculated due to neglect of noticing how water shaped the actual town shape. I guess we’ll see if there would a discrepancy between our maps
