is reading this and is willing to host the data, I'm willing to help with
the design and conversions.

The USGS provides several WMS endpoints for the NHD
<https://nhd.usgs.gov/index.html> , most likely these will connect with
JOSM ( and qGIS ) for tracing or import.

Depending when imports were made will affect the quality - NHD is a moving
target, and as high resolution aerial Lidar and Satellite SAR elevation
data is made available, the resolution improves dramatically. Also, there
are different datasets available for different scales. See
