Mapping watersheds is usually a task reserved for municipalities and conservation authorities, with the goal of restoring or enhancing its health. Started mapping Toronto’s watersheds as a way to understand their extent and reach, and catalogue the common names attributed to smaller tributaries.

Mapping a watershed can also show what opportunities there are to establish great active transportation corridors. Some are “lost rivers”: watercourses that were buried, either without a trace, or leaving mysterious scars in the urban fabric. Some are existing ravines that simply are inaccessible, overgrown, or privatized.

One day, I’ll be able to have comprehensive mapping of the ravines. For now, I’ll catalogue the reach of watersheds and all of the watercourses within them.
