Watershed Geoprocessing Service

Hi,

I have been doing some watershed delineation and testing with the Watershed Geoprocessing service.  I was wondering what data was used to process streams for the tool, like what was the resolution of the stream data?  I have noticed many times the Watershed tool will snap points to a larger stream, when the point should be snapped to the tributary, and is in fact, closer to the tributary than the larger stream.  This obviously occurs only at the mouth of the tributary. 

I know the 30m resolution of the terrain data plays a role in that, but I also wondered about what was used for streams.

Thanks,

-Brett
