A derelict artificial open waterway used for transportation, waterpower, or irrigation.

How to map

Consider using more specific tags using lifecycle tagging.

  • disused:waterway=canal - could be easily put back into service, presumably still holds water.
  • abandoned:waterway=canal - likely to have siltation, be intermittent, or be drained - this one may need additional tags to disambiguate whether it actually contains water.
  • demolished:waterway=canal - filled in, but still signs on the ground

waterway= may mean any of above and therefore is unclear.

To map a derelict canal make a simple way. Add the waterway= tag to it. You should also add a name with name=* if it's known.

When mapping a disused or abandoned canal, you could map the ways representing sections that are dry with this tag, and the sections that are in water with waterway=canal.
