Summary

This tabular data set represents percent of irrigated agriculture, based on 2012 MODIS Irrigated Agricultural Data (MIrAD) data 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 for percent of irrigated agriculture, 2012 MIrAD data was produced by the United States Geological Survey (USGS, 2015). Units are percent. 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 the percent of irrigated agriculture in 2012 for NHDPlusV2 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization.
