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!
