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
