Greetings All.

I have a network dataset of a river, with fish stocking locations as origins and sample sites set as destinations.  For point barriers I have all known barriers which restrict fish passage.  I can solve the ND just fine, and I get distances from my destinations to origins with the barriers working properly.  My problem is: I only want to select the closest barrier to the origin which acts as a barrier to all fish upstream from it, and not ALL the barriers within the system.  Is there a way to select those features without running a fancy script?

Appreciation graciously doled out!

Phil
