This dataset is a continuous parameter grid (CPG) of baseflow index values (percent of discharge as baseflow) estimated at U.S. Geological Survey (USGS) streamgages in the Pacific Northwest. Source data was produced by David Wolock of USGS.

This dataset is a continuous parameter grid (CPG) of mean depth to water table in the Pacific Northwest. Source data come from the Digital General Soil Map of the United States, produced by the Natural Resources Conservation Service, United States Department of Agriculture.

This metadata record describes a series of data sets of climate and land-use/land-cover features (provided in parquet file format) linked to NHDPlus Version 2.1’s (NHDPlusV2) stream segments, their associated catchments and their upstream watersheds within selected regions in the conterminous United States. All data can be linked to NHDPlusV2 using the COMID field in these tables and the ComID in the flowline shapefiles or FEATUREID in the catchment shapefiles in the NHDPlusV2 data suite.

This metadata record documents four 30-meter raster data layers; 1) elevation, 2) hydro-enforced elevation, 3) flow direction, and 4) flow accumulation for the conterminous United States. The datasets are derived from the NHDPlus Version 2.1 regional raster datasets and presented here as Cloud Optimized GeoTIFFs (COGs).

This tabular data represents the area of combined landuse and surficial materials for the conterminous United States linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data are the National Land Cover Dataset (NLCD) representing 2011 ground conditions (Homer, 2013) , and the "Map database for surficial materials in the conterminous United States" produced by the United States Geological Survey (USGS Soller and others, 2009). Surficial materials are defined as an unconsolidated blanket of sediments in which soils commonly are developed. These sediments generally were eroded from underlying rock, and then were transported and deposited (USGS Soller and others, 2009). Reach catchment information characterizes data at the local scale.

This tabular data set represents the percent of surficial materials 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 "Digital data set describing surficial geology in the conterminous US," produced by the United States Geological Survey (Price and Clawges, 1999). Units are percent. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions. Network-accumulated values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing database to navigate the NHDPlus reach network to aggregate (accumulate) the metrics derived from the reach catchment scale. (Schwarz and Wieczorek, 2018).

This tabular data set contains annual information on forestry activity, 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 from the NAWQA Wall-to-Wall Anthropogenic Land Use Trends (NWALT) produced by James Falcone (USGS, 2015). The data provided here contains yearly information from 1999-2012, compiled as described above. The units are percents. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions.
