Assuming you are using ArcGIS Pro 2.8+, you need to use the latest version of Arc Hydro to resolve this issue: http://downloads.esri.com/archydro/archydro/setup/Pro/2.7.37/ Christine Christine Dartiguenave Esri Water Resources Team ... View more

The installer searches the registry for the following registry key / value   HKEY_LOCAL_MACHINE\SOFTWARE\ESRI\ArcGISPro RealVersion   If the value is >= “1.2” then the installation will proceed.   Either the value for RealVersion is less than 1.2 or the installer cannot read the registry value for some reason.

Please try the latest version of GeoHMS 10.7:  http://downloads.esri.com/archydro/HECGeoHMS/Setup10_7/10.7.0.8/ You may need to add the GeoHMS toolbox to ArcToolbox if you get a message stating that the tool is not found. Close the window after adding it. Christine Dartiguenave Esri Water Resources Team ... View more

Have you installed the patch for Spatial Analyst (ArcGIS (Desktop, Engine, Server) 10.6.1 Spatial Analyst Patch ). I just tested with a GRID with 0 and negative values and could not reproduce the issue with the latest version of Arc Hydro (/ARCHYDRO/ArcHydro/Setup/10.6/10.6.0.81/ ). If you still have the issue with this version and the patch installed, I may need to take a look at your data. Christine Dartiguenave Esri Water Resources Team ... View more

For clarification, the values 1,2,4,8,16,32,64 and 128 in the Flow Direction raster indicates that all cells flow into one and only one other cell. When one cell may flow into multiple other cells, the value stored in the flow direction cell is the sum of all potential directions. This usually means that you will end up with sinks - a sink is an area where the flow direction is not precisely determined as going into one and only one direction. When you fill the input dem, you are eliminating the sinks and forcing the water to find a way to flow out. This is the dendritic scenario. Sinks may be real and we have ways to handle them - this is the deranged scenario. Christine Dartiguenave Esri Water Resources Team ... View more

The GeoHMS setup should have installed Arc Hydro 10.7.0.19 but it looks like it fails on an incorrect version check for ArcGIS (10.6 instead of 10.7). We will fix the setup. Meanwhile I have posted the 10.7.0.19 setup for Arc Hydro. Christine ... View more

The objective of this tool was to setup the DEM to obtain a correct flow direction - this is why it was ok to modify the original values. Note that this tool is now deprecated. You should now use instead the tool Create Drainage Line Structures. It will create a Flow Direction raster FdrStr which ensures that the direction in the stream is the ones associated to the digitized direction of the input lines. This raster is then merged with the standard Flow Direction. This way, once the water reaches the streams, it goes in the right direction. Christine Dartiguenave Esri Water Resources Team ...
