Summary

This tabular data set represents the percentages of soils for each STATSGO2 Hydrologic Group compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. The source data is found in the component table from the "STATSGOs" soil database produced by the United States Department of Agriculture (USDA, 2010). The variables included are hydrologic groups. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes [...]

Purpose

This data set was created by the U.S. Geological Survey's (USGS) National Water-Quality Assessment Project (NAWQA) which is part of the USGS National Water Quality Program (NWQP). This effort was undertaken to estimate soil attributes for NHDPlusV2 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization.
