Water Resources
Announcing the National Water Dashboard!
Our new interactive, mobile-friendly tool provides real-time water, weather, and flood information all in one place
Explore the NWDData and Tools
The USGS Water Resources Mission Area provides water information that is fundamental to national and local economic well-being, protection of life and property, and effective management of the Nation’s water resources. Below, find data and tools relevant to a wide range of water resources and conditions including streamflow, groundwater, water quality, and water use and availability.

Geochemical Characteristics of the Conterminous United States: % Na2O
This raster depicts the percentage of lithological sodium oxide (Na2O) content in surface or near surface geology. We derived these rasters by calculating the average percent Na2O content for each map unit in combined surficial-bedrock geologic maps. We used state geologic maps (Preliminary Integrated Geologic Map Databases for the United States, Open File Reports 2004-1355, 2005-1305%2
Geophysical Characteristics of the Conterminous United States: Lithology - Major Oxides Data
This workbook summarizes geochemical data for each lithology contained within the USGS Preliminary Integrated Geologic Map Databases for the United States (Open File Reports 2004-1355, 2005-1305, 2005-1323, 2005-1324, 2005-1325, 2005-1351, and 2006-1272). The geochemical attributes in the “Lith Summary” spreadsheet (tab) are measures of central tendency for all
Geophysical Characteristics of the Conterminous United States: Hydraulic Conductivity (µm/s)
This raster depicts the percentage of lithological the hydraulic conductivity (in micrometers per second) of surface or near surface geology. We derived these rasters by calculating the average conductivity for each map unit in combined surficial-bedrock geologic maps. We used state geologic maps (Preliminary Integrated Geologic Map Databases for the United States, Open File Reports 2004-1355...
Preliminary spatial parameters for PRMS based on the Geospatial Fabric, NLCD2001 and SSURGO
This record serves as a specification of a pre-configured subset of the tables in the Geospatial Fabric Attribute Tables for PRMS (Preliminary)data set(https://www.sciencebase.gov/catalog/folder/537a3ec1e4b0efa8af08150a). This subset provides an initial set of values corresponding to many of the spatial...
GIS Features of the Geospatial Fabric for National Hydrologic Modeling
The Geopspatial Fabric provides a consistent, documented, and topologically connected set of spatial features that create an abstracted stream/basin network of features useful for hydrologic modeling.The GIS vector features contained in this Geospatial Fabric (GF) data set cover the lower 48 U.S. states, Hawaii, and Puerto Rico. Four GIS feature classes are provided for each Region
