Which version of ArcGIS are you using? 10.6.1? Have you installed the Spatial Analyst Patch for ArcGIS? ArcGIS (Desktop, Engine, Server) 10.6.1 Spatial Analyst Patch  Christine Dartiguenave Esri Water Resource Team ... View more

This patch is for ArcGIS 10.6.1 not 10.6. You need to install 10.6.1 first, then the patch. Christine Dartiguenave Esri Water Resources Team ... View more

We are still in the process of moving Arc Hydro Tools to Pro. The best way to call the tools in pro is to use "import archydro" which is available with the most recent setups. You can try to type it in the Python window in Pro. Another way is to import each script. The issue with this method is for tools that have the same name in the core product (e.g. flowdirection or flowaccumulation). You may end up importing the core tool instead of the arc hydro tools. You can look in the tools to see how we are calling other tools (mainly calling the scripts for now) but eventually we will use import archydro. As a side note, the core is working on a tracing network (hydro network) that will allow performing the hydro network analyses in Pro. it should be available early next year.  Christine  ...

We are in the process of migrating/testing the Arc Hydro Tools from ArcMap into Pro, this is why you only see a subset in Pro. In addition, some of the capabilities needed to support the stormwater processes are not yet available in Pro (tracing our hydro network) and should be available at the beginning of next year. So at this time, you need to use the Arc Hydro Tools Python in ArcMap for stormwater. Christine Dartiguenave Esri Water Resources Team ... View more

There can be only one drainage line in each catchment (exception would be nhdplus with very small lines). In your case, the issue seems to be the source data. How did you create the drainage lines? The input streams need to go from confluence to confluence. A stream cannot connect to the middle of another stream as it seems to be the case on your picture. You need to split the long stream at the location where the smaller stream connects. You will end up with 3 drainage lines and 3 catchments. Christine Dartiguenave Esri Water Resources Team ...

This step is not needed anymore. Create Drainage Line Structures and Adjust Flow Direction in Streams will ensure that the water flows in the correct direction. You can check the Stormwater document to see the workflow. Christine Dartiguenave Esri Water Resources Team ... View more

Please install the new patch for 10.6.1 and retest: The ArcGIS (Desktop, Engine, Server) 10.6.1 Spatial Analyst Patch is now live on the support site. The URL is: https://support.esri.com/en/download/7685 Christine Dartiguenave Esri Water Resources Team ... View more

The issue has been fixed with the SDK only. The developers are aware that it is not working in Python and are looking into it. In my case, I had a simple point symbol to assign and the following steps managed to assign the symbology to my new layer: Add the lyrx file to the map: m.addDataFromPath(mysymbologylayerxpath) Get the layer's symbology: mysymbology=m.listLayers()[0].symbology Remove the layer from the map: m.removeLayer(m.listLayers()[0]) Assign the symbology to my new layer in the map: new_layer.symbology=mysymbology They are ways to update some of the symbology properties as well if needed. I did not need to in my case. I hope this helps until the issue gets resolved. Christine Dartiguenave Esri Water Resources Team  ... View more
