Resource Abstract:
- description: This data set represents the estimated amount of phosphorus and nitrogen fertilizers applied to selected crops
for the year 2002, compiled for every catchment of NHDPlus for the conterminous United States. The source data set is based
on 2002 fertilizer data (Ruddy and others, 2006) and tabulated by crop type per county (Alexander and others, 2007). The NHDPlus
Version 1.1 is an integrated suite of application-ready geospatial datasets that incorporates many of the best features of
the National Hydrography Dataset (NHD) and the National Elevation Dataset (NED). The NHDPlus includes a stream network (based
on the 1:100,00-scale NHD), improved networking, naming, and value-added attributes (VAAs). NHDPlus also includes elevation-derived
catchments (drainage areas) produced using a drainage enforcement technique first widely used in New England, and thus referred
to as "the New England Method." This technique involves "burning in" the 1:100,000-scale NHD and when
available building "walls" using the National Watershed Boundary Dataset (WBD). The resulting modified digital elevation
model (HydroDEM) is used to produce hydrologic derivatives that agree with the NHD and WBD. Over the past two years, an interdisciplinary
team from the U.S. Geological Survey (USGS), and the U.S. Environmental Protection Agency (USEPA), and contractors, found
that this method produces the best quality NHD catchments using an automated process (USEPA, 2007). The NHDPlus dataset is
organized by 18 Production Units that cover the conterminous United States. The NHDPlus version 1.1 data are grouped by the
U.S. Geologic Survey's Major River Basins (MRBs, Crawford and others, 2006). MRB1, covering the New England and Mid-Atlantic
River basins, contains NHDPlus Production Units 1 and 2. MRB2, covering the South Atlantic-Gulf and Tennessee River basins,
contains NHDPlus Production Units 3 and 6. MRB3, covering the Great Lakes, Ohio, Upper Mississippi, and Souris-Red-Rainy River
basins, contains NHDPlus Production Units 4, 5, 7 and 9. MRB4, covering the Missouri River basins, contains NHDPlus Production
Units 10-lower and 10-upper. MRB5, covering the Lower Mississippi, Arkansas-White-Red, and Texas-Gulf River basins, contains
NHDPlus Production Units 8, 11 and 12. MRB6, covering the Rio Grande, Colorado and Great Basin River basins, contains NHDPlus
Production Units 13, 14, 15 and 16. MRB7, covering the Pacific Northwest River basins, contains NHDPlus Production Unit 17.
MRB8, covering California River basins, contains NHDPlus Production Unit 18.; abstract: This data set represents the estimated
