This dataset contains watershed means of estimated percent impervious surfaces for three time periods: 1992, 2002, and 2012. Estimates are based on coefficients derived from comparing land use of the 2012 NAWQA Wall-to-wall Anthropogenic Land-use Trends (NWALT) product to the 2011 National Land Cover Database (NLCD) imperviousness, then applying those coefficients to previous years (1974-2002) of the NWALT dataset.

The dataset contains estimates for total phosphorus flux from wastewater treatment plants that discharge to surface water within the Red River of the North Basin in the United States and subbasins. Shapefiles defining the subbasins are available as part of the same data release in which these data are published. Estimates of wastewater treatment plant total phosphorus flux (or load) were calculated by Tammy Ivanhnenko for the years 1978, 1980, 1982, 1984, 1986, 1988, 1990, 1992, 1996, 2000, 2004, 2008, and 2012. Flux estimates were based on the average discharge from the wastewater treatment plants and treatment level, both reported as part of the U.S. Environmental Protection Agency's Clean Watershed Needs Survey,...

This dataset contains values of normal reservoir storage in units of acre-feet per km2, for three time periods: 1992, 2002, and 2012. Values are derived from a slightly-modified version of the National Inventory of Dams (NID) 2013 dataset, for which approximately 10% of records had the dam completion date estimated.

This dataset contains values of soils, climate, hydrologic, topographic, and other geographic characteristics such as drainage area. These are considered "static" characteristics, which do not change over the time period of this study.

These data report the percent of crop acreage, within each basin (basins 1-8, see accompanying shapefiles), enrolled in the Conservation Reserve Program (CRP).
These data describe the percent of cropland harvested as wheat, corn, and soybean within each basin (basins 1-8, see accompanying shapefiles). Data are available for other crops; however, these three were chosen because wheat is a traditional crop that has been grown for a long time in the Basin and corn and soybeans have increased in recent times because of wetter conditions, the demand for biofuels, and advances in breeding short-season, drought-tolerant crops. The data come from the National Agricultural Statistics Service (NASS) Census of Agriculture (COA) and have estimates for 1974, 1978, 1982, 1986, 1992, 1997, 2002, 2007, and 2012. Years with missing data were estimated estimated using multivariate imputation...
This product contains 1,297 watershed boundaries for water quality study sites of the U.S. Geological Survey (USGS) National Water Quality Program (NWQP) Surface Water Trends project. These include sites where water quality information was collected by both USGS and non-USGS agencies. The data consist of 1,285 boundaries in the conterminous United States, and 12 in Puerto Rico. Twenty-seven percent of boundaries were assembled from other efforts within the USGS which are using the same sites, and 73 percent of boundaries were created new for this project. The data are posted as a single shapefile with separate polygons for each boundary.

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.

Monthly mean precipitation for the Red River of the North Basin upstream of Emerson, Manitoba, and subbasins
Land-use estimates for the period 1970-2012 for eight subbasins of the Red River of the North Basin.
This dataset is available from the typeName 'NWC:gagesii_basins' in the referenced Web Feature Service. This dataset, termed "GAGES II", an acronym for Geospatial Attributes of Gages for Evaluating Streamflow, version II, provides geospatial data and classifications for 9,322 stream gages maintained by the U.S. Geological Survey (USGS). It is an update to the original GAGES, which was published as a Data Paper on the journal Ecology's website (Falcone and others, 2010b) in 2010. The GAGES II dataset consists of gages which have had either 20+ complete years (not necessarily continuous) of discharge record since 1950, or are currently active, as of water year 2009, and whose watersheds lie within the United States,...

This dataset contains values of the Palmer Hydrological Drought Index (PHDI) for annual and seasonal periods from 1985-2012. Values are derived from data based on National Climatic Data Center (NCDC) climate divisions, of which there are 344 in the U.S.
Phosphorus estimates, from fertilizer and manure, for the period 1970-2012 for eight subbasins (see accompanying shapefiles) of the Red River of the North Basin in kilograms per square kilometer.
