Yes, it's me in disguise

You know I think leaving out the scale alltogether might be fine, if that is your choice. On the map of a kingdom/continent/world I might object but on a city map I feel like it is not really needed, since hardly anyone actually measures distance or calculates traveling times on those.

The exact thought behind my question was that I was wondering if the west-east river between the enclave and the bazaar would play a role in trade/transportation, or if it would be too small for that. (and subsequently: if it would be of any interest to the citizens of that city to build a channel or something at the thinnest chokepoint around the bazaar)
