I am trying to identify stream networks of a certain area and also differentiate between ones with flowing water year round, intermittently and dry creek beds. What kind of threshold value would I use for the Con tool Expression. Online examples give 100 but that is way too small and has too large of an output of stream networks. I don't want to go too high but also not too low. My max upper value for the Flow Accum tool is 357399264. If anyone has any advise I greatly appreciate it. Thank you.
