Description: Unclassified Drainage Flowlines, 20190426 (1:2,400) - Shows unclassified drainage flowlines in Indiana. Unclassified flowlines are drainages that may or may not have water present outside of a rain even, and may or may not exhibit channelization associated with streams. This layer is derived from the local-resolution National Hydrography Dataset (NHD), and provides currently available data as of April 26, 2019. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. Also, high-resolution NHD, generally developed at 1:24,000 to 1:12,000 scale, adds detail to the original 1:100,000-scale NHD. The local resolution NHD is developed at 1:2,400 scale, and adds even more detail to the NHD. This dataset is complete and includes data for all of the following thirty-eight HUC08 subbasins in Indiana: Auglaize (0410007), Blue-Sinking (05140104), Chicago (07120003), Driftwood (05120204), Eel (05120104), Eel (05120203), Flatrock-Haw (05120205), Highland-Pigeon (05140202), Iroquois (07120002), Kankakee (07120001) Little Calumet-Galien (04040001), Lower East Fork White (05120208), Lower Great Miami (05080002), Lower Ohio-Little Pigeon (05140201), Lower Wabash (05120113), Lower White (05120202), Middle Wabash-Busseron (05120111), Middle Wabash-Deer (05120105), Middle Wabash-Little Vermilion (05120108), Middle Ohio-Laughery (05090203), Mississinewa (05120103), Muscatatuck (05120207), Patoka (05120209), Salamonie (05120102), Silver-Little Kentucky (05140101), St. Joseph (04050001), St. Joseph-Maumee (04100003), St. Mary’s (04100004), Sugar (05120110), Tippecanoe (05120106), Upper East Fork White (05120206), Upper Great Miami (05080001), Upper Maumee (04100005), Upper Wabash (05120101), Upper White (05120201), Vermilion (05120109), Whitewater (05080003), Wildcat (05120107). The following is excerpted from metadata provided by the IDNR: "In order to meet the USGS NHD data model for flowlines, all new flowlines resulting from the Indiana NHD local resolution upgrade project that could not be categorized (artificial path, canal/ditch, coastline, connector, pipeline, stream/river perennial, stream/river intermittent, or underground conduit) were given an FTYPE of Stream/River and an FCODE of Stream/River (46000). Water may or may not be present outside of rain events and may or may not exhibit channelization typically associated with streams. Those features are considered to be Unclassified Flowlines. Records from the reprojected NHDFlowline feature class where FCODE = 46000 were loaded into this dataset. An INDIANA_CLASS field was added to the feature class and all records were given a value of “drainageway.” The FCODE and FTYPE fields were then deleted. All records from the source NHDFlowlines where FCODE <> 46000 can be found in the Classified Flowline dataset."
