Hi all 

      I tried to use Arcgis 10.6.08321 to generate stream link in a large basin. It provides strange results. A lot of zero on stream cells.  While I tried with Arcgis 10.5.1, it is working well. 

      For watershed function, Result from ArcGIS 10.6.08321 has watershed is from 1 to 255. While the pourpoints Id range from 1 to 409. I use Arcgis 10.5.1, the problem disappeared, each watershed has a unique id. 

     How to solve this problem? 

Best Regards

Hong

same data set?

Can you confirm that the extent, cell size, snap raster and coordinate system were the same?

I can confirm everything are the same. I also try arc hydro "stream segmentation "  function. it provides the same result in Arcgis 10.6.08321.

So what you are saying is that Hydro and 10.6 provide the same results, but 10.5 doesn't

Has something changed in the way that things are being calculated?

Is it a visualization/symbology issue?

Have you tried a simple subtraction of the different results to see if the cell values are different?
