I am trying to create catchments for the high resolution NHD stream network and a 10m DEM in the entire state of Texas. So far, I have been processing the Fill Sink operation for 21 days and it still has not completed. I am looking for a way to break the state apart and run small areas that I can then splice back together and still be hydrologically connected. I found an article that discusses “Regional analysis” in ArcHydro, but does not explain the process well enough for me to add into my own workflow. Can anyone supply some guidance?

Great! Thanks for the help.

Great! That works for the most part. I am using HND streams and am having trouble with all of the streams being assigned a river order. I am attaching a gdb with a sample. Here is also a clip of the message that I receive saying that 44 of the segments did not receive a stream order. If you could direct me to a solution I would greatly appreciate it.

I am having the same issue when I use my own streams which have braids and loops. If I let ArcHydro define the streams for me then it works just fine. The jpg that you attached doesn't show any braided streams, but I am wondering if your data did contain braids. I think the Stream Order cannot handle braided networks. Can anyone confirm this?
