Original # of outlets: This is the number of outlets in the raw table.
Table outlets snapped: Not all the outlets will necessarily be
snapped. Outlets that at distance greater than 100* the DEM cell size
from nearest stream will not be snapped.
Duplicate outlets deleted: It is possible that some outlets added from
a table will be snapped to the same location on a stream (typically the
stream’s end point if outlets points are far from the nearest stream). Any
duplicate locations on streams will be removed.
