In 1887, John Bartholomew's Gazetteer of the British Isles described Lagan like this:

Lagan.-- river of Ulster province; rises in mid. co. Down under Slieve Croob mountaim, flows NW. past Dromore to the vicinity of Magheralin, then turns NE., and, passing Lisburn and tracing the boundary between cos. Antrim and Down, falls into Belfast Lough at the town of Belfast; length about 35 miles. The river is navigable for barges of 50 tons to a point 2 miles above Lisburn, where the Lagan Canal begins and continues the navigation past Moira to Lough Neagh, the entire navigable distance being 28½ miles.
