County fresh-water withdrawal water use allocated to relevant land uses in the United States: 1985 to 2010

This product is a series of six national 1-kilometer (km) raster datasets, for five year intervals between 1985 and 2010, representing USGS Water Use "Total Fresh Water Withdrawals", allocated to areas of land use representing anthropogenic use. Pixels representing anthropogenic uses (urban, agriculture, and mining land uses) are derived from the NAWQA Wall-to-wall Anthropogenic Land-use Trends (NWALT) product (Falcone, 2015), a series of decadal national raster datasets for the period 1974-2012. The raster datasets created here are intended as a source of information for estimating water use for watersheds, at the scale of HUC12 watersheds and coarser. Units are millions of gallons per day (mgd) per square km.
