hey all

i have been reading everywhere that "A primary use of the Flow Length tool is to calculate the length of the longest flow path within a given basin'
well i did all the steps until i got the flow length raster.
what is the next step in order to obtain the longest flow or stream in the watershed?

thanks for your help

The longest flow path function is part of ArcHydro. It is free. May take a little while to learn it though.
