I have a river line feature class for Oregon for which I have calculated the number of river obstructions for each river segment. What I want to do know is add a new count for each segment that is essentially an accumulation of those values heading up stream. So basically, starting with the coastal river segments, each up-river segment would add its obstruction_count to the count of the downstream section. The result should be a data-set that can be used to visualize the accumulation of river obstructions towards the headwaters.

What tools should I be looking at for this? Is this a network analyst process? Geometric Network? Any tips on where to start would be greatly appreciated.
