Looks like much of this data already got imported 54 years ago in changeset 1: https://www.openhistoricalmap.org/way/49639254

got it - will fix. Plan is to remove the older data in this case, unless it has been modified. Will examine modification volume to determine if feasible. Otherwise, will revert.

That’s a good plan. The older data appears to be from OSM back when it was under CC BY-SA but isn’t credited. The newer data is clearly in the public domain and well-sourced.
At a glance, the imported SCC waterways appear to be of high quality, but we should double-check the tagging. I think you’ve already noted some of the issues with it, like tiny segments of streams being “underground” just because a bridge passes over them.
Conflict resolution will be annoying but not as bad as it will be if we wait. So far, I’ve modified the Guadalupe River to reflect a change to its course around SJC, and you’ve also split some streams to add them to boundary relations. (I’ve been avoiding that so far, because I haven’t researched which changes are due to avulsion and erosion and which would keep the boundary where it is.)
