The attributes included are: comid, tocomid, ftype, fcode, gnis_name, gnis_id, \nfromnode, tonode, divergence, streamleve, streamorde, streamcalc, reachcode, frommeas, tomeas, \nlengthkm, arbolatesu, pathlength, areasqkm, totdasqkm, hwnodesqkm, hydroseq, dnhydroseq, levelpathi,\nterminalpa, dnlevelpat, terminalfl, terminalfl, wbareatype, wbareacomi, slope, slopelenkm, \nroughness, vpuin, vpuout, rpuid, vpuid. These attributes are\navailable in four formats: csv, fst, parquet, and geopackage. \"fst\" is a high-performance format for\nuse with the R programming language \"fst\" package. \"parquet\" is a high-performance format\nfor use with multiple programming languages (including python) that support the Apache Arrow\nParquet format. Geopackage is an open standard geodatabase format and includes both the \nattributes and geometry included in this data release.\nThe comid field of these data can be used to join to the National Hydrography\nDataset Plus V2.1 (NHDPlusV2) flowline comid or catchment featureid attributes. The included\nattributes follow the same data model as the NHDPlusV2 but include numerous updates and\nimprovements to network connectivity. All attributes that depend on network connectivity\nhave been recalculated.\nVersion 3.0 includes updated flowline geometry in a geopackage geodatabase file with node geometry \ndigitized in agreement with the network topology and all derived attributes compatible with non-dendritic network\nassumptions. Version 3.0 also now includes specific records of edits applied to the NHDPlusV2 from the NWMV2.1\nand E2NHDPlusV2 in seperate geopackage geodatabases.
