ArcHydro License Type??

Discussion created by ChrisQuick on Jan 13, 2011
I was wondering under what type of license ArcHydro is made available to the public?  Is it GNU or the ESRI ATTRIBUTION & LICENSING AGREEMENT (E213 3/09), that was used for ArcScripts, or something else??  There does not appear to be any licensing information included with the downloads.

I just need this for internal documentation for the agency I work for.
