I have been shown the error of my ways. So I went back and changed those streams that had been marked as 'intermittent=dry' back to '=yes' as per standard usage. If I missed any, let me know.
It was also pointed out that I could use 'waterway=wadi' but this does not symbolize, and only shows up as a black line. Thus I hesitate to use this combination. But, in much of eastern Sierra County, this would be appropriate. Any thoughts?
It would be nice if OSM would use a dashed line when streams are marked as 'intermittent=yes' because it looks a little strange to have all these solid blue lines out here in the desert.
When I made maps for Dept of Defense, we categorized drainage with three levels of flow regime: perennial, intermittent and ephemeral. This is because the dry streams (wadi, wash, arroyo) have distinctly different physical characteristics than intermittent streams.
BTW: I finally got smart and used the map function to nail down my location. :)
