Hi jbl0, and welcome to OpenStreetMap! Thanks for helping to update the area post-Helene; certainly a lot has changed.

A few notes for these changes:
- the 'name' tag is used for waterways that have actual names, not just descriptive data. Thus the East Fork New River has a name, but tributaries (there are many) of it are not named 'Tributary of ...'
- The 'tunnel=flooded' tag is used for actual tunnels which carry water. For mapping flood damage from events, we can use the 'damage' or 'hazard' tags.
- The boundary you adjusted is not an actual property boundary, but just an approximation of the woods behind the houses. OSM does not map legal property boundaries or parcels; locally that data are managed by the Watauga County GIS office. So unless the property owner has felled numerous trees to make room for the well house, this data should stay.

I've updated the data to be in line with correct tagging, but thank you for fixing the stream! A lot of waterways have shifted course since the flooding. You can see my changes at https://osm.org/changeset/157984492
