Summary

This tabular data set represents Principal Aquifers and Rock Types 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. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data is the "Principal Aquifers of the 48 Conterminous United States, Hawaii, Puerto Rico, and the U.S. Virgin Islands," produced by U.S. Geological Survey, 2003. Units are percent of catchment underlain by each Principal Aquifer. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions. Network-accumulated [...]

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 the underlying area of principal aquifers for NHDPlusV2 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization.
