Hi everyone,
I was wondering if anyone knew of any help files or detailed documentation to help me understand what all the sink tools leading up to "Fill Sinks" are actually doing.  I'm mainly struggling to understand what the "sink prescreening" tool does, especially how to decide what your minimum drainage area should be.
I have the ArcHydro tutorial pdf file which seems to be the only help file available, but it is not very detailed.
