I am pretty new to using ArcMap but I am hoping someone may be able to help me with my issue anyway. I have a HUC8 overlay(watershed boundary map) and a digital elevation dataset. I want to be able to examine any watershed and know what upstream watersheds are contributing flow to a particular watershed. I have been shown the flow direction tool, watershed tool, and flow accumulation tool but am still having some issues. Basically, I just want to be able to look at an individual watershed and know what watersheds flow into it. Is there a way to do this?
