Summary

This tabular data set represents the contribution of phosphorus (P) to streams from weathering and erosion of surficial geologic materials compiled for two spatial components of the NHDPlus version 2.1 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 from the publication, Watershed Potential to Contribute Phosphorus from Geologic Materials to Receiving Streams, Conterminous United States, (Nardi, 2014). Units are Mean bed sediment phosphorus value in parts per million (ppm). Reach catchment information characterizes [...]

Purpose

This effort was undertaken to estimate the contribution of phosphorus (P) to streams from weathering and erosion of surficial geologic materials for NHDPlusV2 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization. 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).
