Exactly the same problem here, empty Adjoint Catchment feature class while Catchment is fine. Large domain, small stream initiation threshold. I don't really need the Adjoint Catchment since I'm only interested in a particular set of pour point, but the batch watershed processing uses the Adjoint Catchment feature class as an input. Most of the basins defined using a set of 24 batch points look fine but some have clipped, linear borders. Wondering whether the empty Adjoint Catchment feature class could be the cause. But, who knows, the ArcHydro Tools have so many bugs. Anyway, starting over with smaller stream threshold yields Adjoint Catchments, but much bigger than I need.

Thanks, Mark. The community is grateful for the service you provide. BTW, I am processing large basins (Ganges, Indus, Brahmaputra, Amu Darya, Syr Darya, separately, using a 90m DEM) so I wonder whether I'm running into issues with the attribute tables being too large. I don't recall running into problems when I process small basins.

p.s. I was running on an HP desktop, 8 cores, 32 GB RAM. Thinking the problems were somehow tied to my installation, I began running ArcGIS 10.4 on a Parallels VM on my macbook. Exact same behavior - continual crashes. Makes me think the problem began with recent versions. I was running hydrotools under 10.1 and 10.2 with no problems

the maddening thing is that when ArcHydro crashes map there is (apparently) no log to diagnose what went wrong. I'm getting the impression it has something to do with writing or modifying the files that it creates. For example, I can get through the processing step all the way to creating the catchment polygons. The processing takes several minutes, then ArcMap crashes ("encounters a serious error"). However, the "catchment" feature layer is in fact created, but it's attribute table doesn't have HydroIDs in it. No amount of coaxing will get hydrotools to execute past this step.

I seem to be digging myself into a deeper hole. Can't finish an archydro project due to the tools throwing errors or ArcMap crashing. I keep starting clean projects in new directories, following your advice, hoping something will magically get resolved, but now merely attempting to set default locations causes ArcMap to crash. Installed 10.4.With last project I got all the way through defining the catchment grid but it exited with error at the polygon processing step. I've cleared my temp folder, have lots of RAM and diskspace. I've successfully been creating catchments for years.

I want to use a shapefile I have for a lake as the only sink in a deranged basin, but the Create Sink Structures routine will not accept the shapefile. Is this because it expects to find HydroIDs in the attribute table?

Perhaps my long-winded intro kept folks who might have an answer to my question from reading the whole post. The gist of my problem is: I want to use a shapefile I have for the Aral Sea and Small Aral Sea as the only sinks, but the Create Sink Structures routine will not accept this shapefile. Perhaps it's looking HydroIDs in the attribute table of the polygons?

I'm attempting to create subbasins for the deranged Aral Sea basin, which contains the major rivers Amu Darya and Syr Darya. I'm using a custom SRTM-GDEM blended DEM (90m postings in Albers Equal Area). When I prescreen sinks, if I set a low threshold for drainage area I get 1 million or more sink polygons. If I set a high threshold it misses the Aral Sea and Small Aral Sea (which are really all I need to leave as sinks as these are the end points for the Amu Darya and Syr Darya) because the area around the seas is very flat with many sinks each having a drainage area (it would be much preferable if Sink Prescreen allowed selection by sink area rather than drainage area). So, I want to use a shapefile I have for the Aral Sea and Small Aral Sea as the only sinks, but the Create Sink Structures routine will not accept the shapefile (it wants HydroIDs assigned to the polygons?) How to proceed?

I've discovered that my SinkPoly grid is not recognized in the Data Management window as being a valid sink polygon (i.e. I can't assign that layer in the data management window). I can fill sinks if I do not use the deranged polygon option (the layer that is somehow invalid) but then when I try to adjust flow direction with sinks I cannot select the sink polygon layer. Any ideas?

I have executed many successful workflows with my current setup. It was only when I began creating sink polygons for a deranged basin that I ran into this problem. I think my setup is fine.

I am using for the first time the deranged basin workflow in ArcHydro in ArcGIS 10.3. All goes well with the DEM preconditioning, I successfully defined sink polygons with larger ones set to IsSink =1. But when I execute Fill Sinks, it runs for a while but ultimately end with a (typically) undecipherable error message. Tried closing and reopening the proejct. Same result. Any suggestions besides upgrading to 10.4 (which I'm willing to do, just something I've been putting off)
