This tabular data set represents the number and density of major National Pollutant Discharge Elimination System (NPDES) sites, as defined by Environmental Protection Agency (EPA), compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) number and desnity of major sites per individual reach catchments and 2) number and density of major sites 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 was acquired by James Falcone (USGS, written commun., 2010) from the EPA. Reach catchment information characterizes data at the local scale. Reach catchments...
This tabular data set represents percent of irrigated agriculture, based on 2012 MODIS Irrigated Agricultural Data (MIrAD) data 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 percent of irrigated agriculture, 2012 MIrAD data was produced by the United States Geological Survey (USGS, 2015). Units are percent. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river...
This tabular data set represents percent of irrigated agriculture, based on 2007 MODIS Irrigated Agricultural Data (MIrAD) data 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 percent of irrigated agriculture, 2007 MIrAD data was produced by the United States Geological Survey (USGS, 2015). Units are percent.

This tabular data set represents the estimated percent area of subsurface drainage for the year 1992 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 are "Subsurface Drains on Agricultural Land in the Conterminous United States, 1992: National Resource Inventory Conservation Practice 606" produced by the United States Geological Survey (Wieczorek, 2004). Units are percent. Reach catchment information characterizes data at the local...
This tabular data set represents the estimated percent area of subsurface tile drainage extent from the early 1990's 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 are "Estimates of subsurface tile drainage extent for the conterminous United States, early 1990s" produced by the United States Geological Survey Nakagaki, 2016). Units are percent of catchment. Reach catchment information characterizes data at the local scale. Reach catchments...
This tabular data set contains decadal information on dams 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 dam information was produced by the United States Army Corps of Engineers. The information provided here contains the number of dams (both major and minor), dam storage (acre feet) and decade of construction compiled as described above. Reach catchment information characterizes data at the local scale. Reach catchments accumulated...
This tabular data set represents percent of irrigated agriculture, based on 2002 MODIS Irrigated Agricultural Data (MIrAD) data 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 dataset describes attributes of surface-water impoundments derived from the National Inventory of Dams (NID), National Land Cover Data (NLCD) and the National Hydrography Dataset Plus (NHDPlus). Reservoir surface areas were determined using National Inventory of Dams Reservoir Surface area, NHDPlus Waterbody area, and National Land Cover Data (NLCD) open water body area as data sources. National Inventory of Dams were indexed on NHDPlus V2.1 using several sources and methods which are described in detail in the Process_Description section. The open-water classification in the NLCD was used to extract open water areas.
This tabular data set represents the estimated percent area of agricultural land drained by field ditches for the year 1992 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 are "Surface Drainage, Field Ditches on Agricultural Land in the Conterminous United States, 1992: National Resource Inventory Conservation Practice 607" produced by the United States Geological Survey (Wieczorek, 2004). Units are percent of catchment. Reach catchment...
