Database of modified routing for NHDPlus version 2.1 flowlines: ENHDPlusV2_us This database (ENHDPlusV2_us) contains a topologically reconditioned (enhanced) version of the U.S. Environmental Protection Agency (USEPA) and the U.S. Geological Survey (USGS) NHDPlus Version 2.1 (NHDPlusV2) flowline network. The comma separated file included in this release contains routing and stream connection information, with the intention of improving accuracy and networking capabilities. The enhancements described here include corrections to inconsistencies in network and routing information, filling-in missing attribute values of associated characteristics, and revisions to diverted flow routing. The database is intended for routing purposes only; no cartographic changes were made to the original NHDPlusv2...
