Resource Abstract:
- description: This data set represents the 30-year (1971-2000) average annual precipitation in millimeters multiplied by 100
compiled for every catchment of NHDPlus for the conterminous United States. The source data were the "United States Average
Monthly or Annual Precipitation, 1971 - 2000" raster dataset produced by the PRISM Group at Oregon State University.
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
