Hello,

I'm trying to run the Create Sink Structures from ArcHydro tools in ArcMap 10.6.1 (upgrade is not an option). Whatever the size of the raster (I tried 3 Go, then cropped it to 37 Mo and now 1 Mo), the script just keeps running and then ArcMap falls into "not responding" mode. I tried working with .tif and gdb raster. I'm using a Nad83 CSRS MTM  projection for all the inputs. I have 8 Go ram, i5 core and SSD disk with 70 Go space left. 

I don't understand what's happening. Has anyone experienced similar issue and found a work around?

Cheers,
