"it would be an explicit way to tag the beginning, otherwise you can't tell whether the start of a river in OSM is also the start of the actual river, or if there are missing parts in OSM." You make a good point Martin. I hadn't thought of that but that's another reason for using an explicit tag.

Thanks. Actually, the example you gave uses the tagging Stephan suggested, that is, to tag the first node of a waterway with natural=spring. Apparently, the Thames rises from a spring. I found several other examples using Overpass Turbo and I think the tagging below is good waterway=source name=Co

>This mentions to optionally add a role "spring" for the "spring" node. Not in this case. If the stream started at a spring, that is a place where water comes from the within the earth, that would be fine but the Colville begins at the place where two smaller streams come together to form a larger

I'm wondering if it's possible to tag in some meaningful way, the place, usually a node, where a river begins. It seems this would be of interest to people besides myself but I don't think there is currently a way to tag such a place. Using as an example, the beginning of a major Alaskan river, th
