[GRASSLIST:10579] Re: Stream network in GRASS?

[Jonathan Greenberg]

Michael:

	Thanks!  I was playing with r.watershed today, and running it on a
tutorial DEM from the DHSVM hydro modeling toolkit was resulting in the
streams output from r.watershed (which I'm assuming I would use to create
the vector) had values for every cell, not just the valley/stream cells.  Is
there a way to have a grid of only "river" cells, not all flowlines created
from the dem?
