Thanks to Markus and Ivan for the help-- I'll answer this on the forum in
case others have the same problem in the future.
For the record, I am using GRASS 6.4.4 on Mac OS 10.9.5.
The problem was that though I ran r.fill.dir once, there were still sinks
in my DEM. After running r.fill.dir 5 total times, I removed all of the
sinks in the DEM and r.drain worked well.
Thanks for indulging a new user!

Hi,
could be that the dtm is not really/completelly filled. Please try to
verify the elevations of the dtm cells surrounding the one where the drain
stops.

Hi all,
I am using r.drain with an elevation raster as input. I filled the
elevation
raster using r.fill.dir. When I run r.drain, it only creates a short path
segment before finishing the analysis, even though it hasn't come close to
the region border. There should not be any sinks in my elevation raster
because I filled it. Does anyone have any experience with this problem?
Thanks!
Charlie
