I am using Arc Hydro tools, but whenever I reach stream definition, it fails, giving error 000860. Yet I think I have done everything right. What could be the problem?
I have run DEM reconditioning, filling sinks and store my work on local disk C:. I projected my datasets to the same cordinate system but all in vain. I am using ArcGIS 10.3 and Arc Hydro 10.3
