hey thanks for all your edits !! just an FYI that the recommended approach these days is to continue the stream line through any ponds/river areas like https://osm.org/way/370832200 

you might actually find it faster to right-click the stream's end point and then click "Continue", rather than adding every pond to the relation.


both options work fine, but connecting all the river/stream lines has an added benefit since it allows us to generate watershed maps like https://waterwaymap.org/#map=6.23/-38.53/175.096
