Description: This dataset includes flowline data that are contained by a subbasin that overlaps the 16-county NCTCOG region. The data are extracted from the NHD. The NHD is a digital vector dataset that contains features such as lakes, ponds, streams, rivers, canals, dams and stream gages. NHD Flowlines dataset consists of routes that make up a linear surface water drainage network. Flowlines have a reach code and a measure, allowing for the establishment of upstream/downstream relationships. This network allows for powerful analysis and modeling capabilities. Each Feature type is attributed with descriptive information by an Fcode. For more information about NHD features, see the Feature Catalog at http://nhd.usgs.gov/FeatureDirectory.swf. The NHD is a combination of USGS hydrologic digital line graph files (DLG) and EPA reach files, version 3.0 (RF3). The USGS files were used for spatial accuracy and the EPA files were used for attribute information. This dataset was downloaded from http://nhd.usgs.gov/data.html and processed but otherwise unaltered. This file is for reference use only. NCTCOG and its members are not responsible for errors or inaccuracies in the file.
