12-Digit Hydrologic Unit Outlet Locations for Selected Watersheds Draining to the Gulf of Mexico in the South-Central and Southeastern United States, Derived from the USGS Watershed Boundary Dataset (dated August 13, 2020) and NHDPlus version 2.1

This USGS data release includes a shapefile of outlet point locations for 12-digit hydrologic units (HU12s) from the Watershed Boundary Dataset (WBD), dated August 13, 2020 (U.S. Geological Survey and others, 2020), draining to the Gulf of Mexico in the south-central and southeastern United States. The outlet locations were derived by combining the WBD boundaries with flow direction grids from the National Hydrography Dataset Plus (NHDPlus) v 2.1 (U.S. Environmental Protection Agency and U.S. Geological Survey, 2012). Most of the outlet locations were determined by finding the cell with highest flow accumulation from the NHDPlus flow-direction grids within each WBD HU12 boundary. Some locations were found to be...
