I checked the GRASS archives and could not find a utility to remove
depressions from digital elevation model data. Does anyone know
where I can get one? This tool is especially useful for those of
us running hydrology applications in conjuction with GRASS. You can
reply to this message or email me directly. Thanks in advance!

Thanks for the e-mail help.
Here are two of the e-mail responses I received:

About removal of depressions in DEM's:
In the "Related" part of GRASS is a collectione of programs for distributed
hydrological modeling (its called "ANSWERS"). One of these programs is called
"r.fill.dir" and should create depressionless DEM's.
I have not tested it but it might be what you are looking for. The source is
located under /grass/grass4.1/release/related on the moon.

John,
In the rsc.src contributed code directory distributed with GRASS
there should have been some code on a water quality assessment tool called
WRAT. One of the modules within this model, accepts a DEM as input and
outputs an idealized DEM with no pits or depressions.
If you do not have this code and cannot find it let me know and
I will try to get you the binary.
