Mike, I was reading through the posts and remembered that NHDPlus (I'm
pretty sure) has contributing area information associated with the
monitoring stations. Check it out!

Subject: shrug-l: proportion of watershed upstream of monitoring
location
I have a point shape file of monitoring locations on rivers. I have a
shape file of the watershed polygons in which those monitoring stations
are located. For a particular monitoring location, how do I calculate
the proportion of the watershed that is upstream from that location?
Thanks,
Mike
