Blow-Me-Down Brook, NH – An NHD Flowline Picked ‘Randomly’

I am working on some hydroaddressing / network traversing technical approaches for 3DHP – and needed an example of a multisegment flowline in NHD-sourced dataset, and so ‘randomly’ got this one - Blow-Me-Down, NH, from WBD HUC4-0108.
Although we map so many flowlines (~20 million in the USA for NHD-sourced spatial data, estimated 10x that for the EDH data still to be determined across the USA), I like trying to understand what a flowline or waterbody ‘is’ to the people on the ground as much as I can...
