This metadata record describes 26 30-meter raster data sets that estimate the percent of agricultural land that may be subject to select conservation practices for each year during the period 2000-2012. The data were derived from U.S. Department of Agriculture (USDA) National Resources Conservation Service (NRCS) National Resource Inventory (NRI). One set of rasters (denoted by the ICP prefix) represents an estimate of the percent of agricultural land potentially subject to Alley Cropping, Contour Buffer Strips, Contour Farming, Contour Orchard/Other Fruit Area, Cross Wind Trap Strips, Field Border, Filter Strip, Grassed Waterway, Hedgerow Planting, Herbaceous Wind Barriers, Irrigation System, Tailwater Recovery,...
This tabular data set represents the percent of land cover classes from the 2006 National Land Cover Dataset 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 is the "National Land Cover Database 2006" produced by the United States Geological Survey (Fry and others, 2011). Units are percent. The "National Land Cover Database 2006" (NLCD 2006) is a 16-class (additional four classes in Alaska only) land cover classification scheme that...
This metadata record describes three best management practice scenarios for Nitrogen, Phosphorous, and Sediment based on information from the National Resource Conservation Service. The potential benefits of agricultural management practices were developed by USDA using estimates of nutrient and sediment reductions from agricultural fields due to the implementation of a suite of Best Management Practices (BMP's) (USDA, 2012). Estimates of losses were developed by the USDA Conservation Effects Assessment Program (CEAP) using a sampling and modeling approach. Data collected by the National Resources Inventory (NRI) Program were utilized to characterize representative agricultural areas for features such as soils,...

This dataset represents 9,097 basin boundaries (rdews_gages.shp) of select U.S. Geological Survey's (USGS) active and historical stream gages derived from the published datasets of stream gage basins (Wieczorek, 2006), GAGESII (Falcone, 2011), and delineated from digital elevation models found in the NHDPlus version 1 data suite (NHDPlus, 2006). These basins were created to assist in spatial processing of model inputs for the U.S. Geological Survey's (USGS) Data-Driven Drought Prediction Project of the Drought Science Program within the Water Resources Mission Area's Water Resource Availability Program.
The Geospatial Fabric version 1.1 (GFv1.1 or v1_1) is a dataset of spatial modeling units covering the conterminous United States (CONUS) and most major river basins that flow in from Canada. The GFv1.1 is an update to the original Geospatial Fabric (GFv1, Viger and Bock, 2014) for the National Hydrologic Modeling (NHM). Analogous to the GFv1, the GFv1.1 described here includes the following vector feature classes: points of interest (POIs_v1_1), a stream network (nsegment_v1_1), and hydrologic response units (nhru_v1_1), with several additional ancillary tables. These data are contained within the Environmental Systems Research Institute (ESRI) geodatabase format (GFv1.1.gdb).

The Transboundary Geospatial Fabric (TGF) is a dataset of spatial modeling units consistent with the Geospatial Fabric for National Hydrologic Modeling (abbreviated within this document as GFv1, Viger and Bock, 2014). These features were derived from National Hydrography Dataset Plus High Resolution data (NHDPlus HR, U.S. Geological Survey [USGS], 2018) in the following conterminous United States (CONUS) - Canada transboundary four-digit Hydrologic Units (HUC4): 0101, 0105, 0108, 0901, 0902, 0903, 0904, 1005, 1006, 1701, 1702, and 1711. The data described here include the following vector feature classes: points of interest (POIs), a stream network (nsegment), major waterbodies (waterbodies), and hydrologic response...
This metadata record describes the average of annual maximum duration of consecutive dry and wet days per event, where precipitation totals are 0 or equal and exceeds 1 millimeters respectively, during the 30-year period 1981 – 2010 for the conterminous United States. A wet event is defined as a period when the number of consecutive days with precipitation equals or exceeds 1 millimeter. A dry event is defined as a period when the number of consecutive days with precipitation equals 0 millimeters. The source data was produced and acquired from DAYMET (2018) and is presented here as a 1-kilometer resolution GeoTIFF file.
This tabular data set represents estimated loads of nitrogen and phosphorous from fertilizer and manure applied on agricultural land for the year 2012 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 estimated loads of nitrogen and phosphorous from fertilizer for 2012 was produced by Brakebill and others, (USGS, 2017) and the source data for estimated loads of nitrogen and phosphorous from manure for 2012 was produced by Gronberg...
This tabular data set contains information on percent of wild fires per catchments for the years 2000 through 2012, and 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.

This metadata record describes a computed ratio of county acres of farmland reported in agricultural conservation programs to the total acres of farmland reported for the county. Acres in conservation programs are for the 2012 time period, and reported by survey from the U.S. Department of Agriculture, Farm Field Survey. Acres of total farmland were used from the U.S. Department of Agriculture, 2012 Census of Agriculture. The ratio is intended to provide an indication of the intensity of agricultural management practices.
