I'm in the UK so I'm not familiar with NHD, but here I am familiar with
streams here traced from NPE (old maps, very inaccurate by modern
standards). NPE-traced streams can be useful in that they can tell you
that there's a stream here somewhere, but you absolutely can't use them
to tell which side of the water you're supposed to be on (or reliably
count crossing streams before a path junction).
However it is possible to use the tags on them to make it clear to
someone looking at the data where it came from. For Garmin maps I
append "(NPE)" to the name of NPE-traced streams and you could certainly
do something similar with NHD ones.
OSM has always proceeded by evolution - stuff I added 9 years ago is
considerably less accurate than stuff I add now because there were fewer
sources available to compare - and EGNOS wasn't available then (at least
not to me). I'm sure that what I add now will appear "similarly
inaccurate" in 9 years time!
Best Regards,
Andy
