watershed delineation

[Teresa Salyer]

Is there a program in grass4.1 that can take a Digital Elevation Map and
if you know the lat and long of a watershed outlet it will delineate the
watershed above that refrence pt.   If you have any suggestions it sure
would be helpful.  Thanks Again, Teresa Salyer
