River Basins
Wake County is split between two River Basins (6-digit Hydrologic Unit Code), the Cape Fear River Basin and Neuse River Basins. River basins are determined by the US Geological Survey (USGS). USGS delineates drainage areas at 6 different levels all nesting within each other. These levels start at a regional scale and are given a 2-digit Hydrologic Unit Code (HUC). Two digits are added to the code at each level as it progresses to a smaller drainage area. River basins are at the third level and designated with a 6-digit HUC.,

Major Utility Easements
공공데이터포털
,Major Utility Easements in Wake County, North Carolina. This dataset was compiled from multiple reputable sources. Liquid and gas pipeline data were obtained from the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) National Pipeline Mapping System (NPMS). Electric transmission and gas easement data were derived from NC OneMap, specifically the Duke Energy Transmission Easements layer.,
Attributes for NHDPlus Version 2.1 Catchments and Modified Routing of Upstream Watersheds for the Conterminous United States: Major Sites of the National Pollutant Discharge Elimination System (NPDES)
공공데이터포털
This tabular data set represents the number and density of major National Pollutant Discharge Elimination System (NPDES) sites, as defined by Environmental Protection Agency (EPA), compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) number and desnity of major sites per individual reach catchments and 2) number and density of major sites accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data was acquired by James Falcone (USGS, written commun., 2010) from the EPA. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions. Network-accumulated values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing database to navigate the NHDPlus reach network to aggregate (accumulate) the metrics derived from the reach catchment scale. (Schwarz and Wieczorek, 2018).
