text: Hi,
  This stream was an import of water features, many of which no longer exist.
  Looking at ESRI leaf-off imagery at zoom level 21, I believe I can make out where the stream is between the railway and where it merges into Glade Creek.
  This appears to be some 15 metres or so southwest of the map data.
  On the Vinton side of the railway I would guess the stream is underground.
  I can then again identify it on the imagery where it appears from South Blair Street, 12m south of an unnamed service road between it and Church Street.
  East of here, past a footbridge, it may disappear underground again as the shadows in the orthophotos are too bad.
  Then the sharp photos turn into a blurry mess where it may reappear.  Yeccch.
  I might see it there too, but it's too small to be sure.
  So yes, there is a stream largely underground, but in part visible.  Its actual location is somewhat off thanks to the lower quality of these old imports compared to the resources available now.
  Hope that helps, if you are a local!
