Years ago, I saw a picture of a pool floating in a river. It seems like the best of both worlds, the controlled water of a pool surrounded by larger expanse of cool water. This came to me as perfect way to finish off my series of canal modules.

As I get near the end of the canal-building phase of my project, it occurred to me that I wanted my canal to have a history of use beyond recreation. I pictured small boats carrying goods through the city. That would mean canal-side businesses and warehouses.

A canal isn’t much of a canal without boats to travel its length. If you have boat traffic, then you’ll have places for those boats to tie up.
