Discussed on Slack. Transcript below. Looks like these are all incorrect
values from an old import and the water=salt tag can either be removed or
in some cases the water areas can just be deleted where they don't exist in
reality.

As already described in my mailing list post
<https://lists.openstreetmap.org/pipermail/talk/2021-November/087079.html>,
I would like to conduct a rather big edit, changing water=salt to salt=yes .
What would y'all US people think of that? While I would prefer an answer on
the mailing list, an answer here is fine too.Thank you. (edited)

on the one hand, i favor consistent tagging that is aligned with current
standards. on the other hand, big mechanical edits tend to trigger a lot of
discussion (see current discussion about a big mechanical edit of name and
name:en tags on the talk-us list, and ongoing discussion of efforts to
cleanup some river tagging.)

I think, as the edit is something so dead-simple and will only happen once,
it isn't going to be a big deal for anyone

Also, since salt=yes yes is part of a by now 10 year old ACCEPTED
proposal, it's long overdue

it will, nonetheless, attract attention, best to discuss it with the kind
of folks who tend to take notice of it beforehand.

It appears to be that all the water=salt areas are in one NHD import in NM
and CO?

Also, I was wondering about them all being in two states too. They seem to
have been added at one time. Maybe an import?

i’d say reduce it to the NM and CO areas and look for that community to
interact with. i don’t know if we have local-colorado and local-new-mexico
groups or not.

yes, that was an NHD import some time ago. it’s an import that probably
seemed like a good idea at the time, but maybe wasn’t really. it was
already out of date in a lot of areas even as it happened.

I'm spot checking the ones in that western block and they're mostly
intermittent=yes and located on dry washes. Easy to believe that they
might be salt in the rainy season.

It's a lot harder to believe there are a lot of saline features in
Minnesota, Wisconsin or the Upper Peninsula. That area is kind of soggy.
There are a bunch that look to be oxbow lakes that I'd be pretty sure are
'fresh' water (stagnant and likely acidic, but not salt!)

@Emil <https://osmus.slack.com/team/U02HAL3CYCD> - This exercise is
basically going through, 'how did the data get there in the first place,
and do we want an edit simply to alter the tagging, or was the information
wrong to begin with?' It'll do little good to replace bad data with more
bad data.

Speaking for Colorado, it does look like mostly just spurious NHD tags.
Maybe at some point there was a tag that was meant to indicate "not good
drinking water" that was reinterpreted to just mean "salt". Those little
washes are probably minerally and crappy water when they fill in, but I
wouldn't call them "saltwater" in the usual definition.

I wouldn't say there are NO natural salt water bodies in CO, but I don't
see anything that meets that description in the tagging of water=salt in CO
and NM.

OK, not familiar with that part of the Rockies. Little intermittent ponds
like that in AZ might well be salt, as well as being loaded with lots of
other mineral nasties (heavy transition metals, arsenic, selenium, ...)

I would be in support of simply removing water=salt on any NHD imported
feature in CO or NM. If the last edit was by nhd-import or ppjj (who did a
mechanical fix of intermittent tags last year) then it should be safe.

My guess is the NHD stuff went back to some intern digitizing from USGS
topos and mistaking the hachure for 'intermittent' with the one for 'salt'.

Also, the water=salt usage is specifically called out in the NHD fixup
documentation as an original mistake:

Well there we go, that basically seals the deal. Humorously the only place
in CO where I know there are some salt water springs is NOT tagged with
water=salt or salt=yes.

According to https://wiki.openstreetmap.org/wiki/NHD_Rules (it sure does,
doesn’t it!), FCodes 39001 and 39003 were both mapped to type=salt, which
later got changed to water=salt to avoid conflicts w/ multipolygon
relations.

In any case, @Emil <https://osmus.slack.com/team/U02HAL3CYCD>, it looks as
if you've got a whole squad of USAian mappers on the case -- you might
wind up not having to do anything at all beyond having called attention to
it.

https://nhd.usgs.gov/userGuide/Robohelpfiles/NHD_User_Guide/Feature_Catalog/Hydrography_Dataset/Complete_FCode_List.htm
says FCode 39001 means “Hydrographic Category|intermittent”, which should
definitely be tagged intermittent=yes, nothing about salt.

FCode 39003 is no longer used, but an older revision
<http://archives.waterinstitute.ufl.edu/suwannee-hydro-observ/datasets/base-layer-metadata/hydrography/chp1_NHD_users_guide.pdf#page=48>
defines it as “Hydrographic Category|perennial; Water
Characteristics|salt”. Unfortunately, the NHD import didn’t distinguish
between these two FCodes, which are complete opposites. [image:

Oh, I see, 39001 was “Hydrographic Category|intermittent; Water
Characteristics|salt” in that revision of NHD. So I guess we’re back to
wondering why it thinks these are salty.

Since all information about salinity is removed from the current schema,
I'm guessing that there was enough hopelessly miscoded crap that USGS gave
up.

USGS maps used to be the envy of the world, but the survey was severely
defunded in 1991 and has been struggling ever since.

Seems pretty clear all these water=salt tags should just get removed.

Why don’t the boundaries on US Topo maps match and why are some missing?
<https://www.usgs.gov/faqs/why-don-t-boundaries-us-topo-maps-match-and-why-are-some-missing>
Boundaries are an ongoing issue for the US Topo project due to the lack of
national GIS datasets suitable for general-purpose, 1:24,000 scale maps.
The earliest US Topo maps (2009-2010) showed no boundaries other than the
U.S. national boundary. In 2011, state and county boundaries were added
using TIGER data from the U.S. Census Bureau. Federal land boundaries are
