See Full Metadata Here This dataset contains the initial 3D Hydrography Program (3DHP) flow network based on the final High Resolution National Hydrography Dataset(NHD) and a set of mainstem rivers built on the Medium resolution NHDPlus Version 2(NHDPlusV2). Two key pieces of information have been added to the flow table of the National Hydrography Dataset: 1) at every junction, one and only one main upstream and downstream connection have been identified 2) every "in network" flowline has been assigned a mainstem identifier that places it into a hierarchy of rivers and drainage basins. For description of 1 and 2 and additional background, see supplemental information. Files included: - HU6_mainstem_outlets.geojson...
