I’m adding streams, arroyos, buildings etc.as well as updating roads in Sierra County NM. Most of the drainage in this area is dry except immediately after rains. Tagging them “intermittent=yes” does not seem appropriate, as they are really ephemeral. I have started tagging these dry streams and arroyos as “intermittent=dry” and I will go back and change the rest as time permits.

Just to make you aware, intermittent=yes is the accepted way for tagging these.
See osm.wiki/Intermittent
There are over 724,000 instances of intermittent=yes with several hundred thousand occurrences of water/streams tagged as such, see http://taginfo.openstreetmap.org/search?q=intermittent#values
This is versus 561 results for intermittent=dry, 560 of which are assigned to streams in New Mexico by yourself and weirdly form a single straight line, see http://overpass-turbo.eu/s/4uc
It is up to you, but in your shoes, I would be tagging as intermittent=yes as this is the standard accepted way of tagging for this type of feature

Looking at the help, it looks like you should use waterway=wadi as this “stream” is mostly dry except after rains…
waterway=wadi
