I can't find any information – neither on the English wiki nor on the Russian translation – that either waterway=drain or waterway=ditch is used for irrigation. They are both used to tag stretches of waters carrying superfluous water, e.g. for drainage. As defined on the wiki, the difference between ditch and drain is that waterway=drain is lined with concrete or similar: https://wiki.openstreetmap.org/wiki/Tag:waterway%3Ddrain If you want to tag an artificial stretch of water used to carry useful water for irrigation – as well as transportation and power generation –, there is waterway=canal: https://wiki.openstreetmap.org/wiki/Tag:waterway%3Dcanal Regards Markus _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
