How to select stream network between points? Report this article as Inappropriate to us !!!Login to Reply

I'm trying to select features of a stream network from the NHD (national hydrography dataset) between related points on the network. 

I can select the network upstream or downstream from a point to the end of the network using NHD tools, but I'm uncertain of a practical method for terminating the selection at these specified points. The big issue I'm finding is that the selection needs to work upstream from a point and include all branches up to where the network either terminates or there is another boundary point. I'm thinking there may be options in Network Analyst or ArcHydro that I am not familiar with - anyone with more experience with these tools have any ideas?
