[Tagging] Tagging estuaries: estuary=yes or river=estuary?

[Dave Swarthout]

Hi Clifford,

Can you help me find something in the Skagit Delta that is tagged with the
estuary tag? When I read your post, I immediately tried to check it out
because I'm trying to understand how that tag is being used currently. But
I wasn't able to find anything.

Thanks for your help.
