Water Resources

Data 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.

USGS Flood Event Viewer

During large, short-term events, the USGS collects streamflow and additional data (including storm tide, wave height, high-water marks, and additional sensor deployments) to aid in documenting flood events. The USGS Flood Event Viewer provides convenient, map-based access to downloadable event-based data.

StreamStats Application

StreamStats provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. The map-based user interface can be used to delineate drainage areas, get basin characteristics and estimates of flow statistics, and more. Available information varies from state to state.

Annual Water Data Reports

Annual Water Data Reports were published annually for many decades as static archival products that supplemented direct access to current and historical water data provided by the National Water Information System (NWIS). This site helps users access historical Water Data Reports, electronic Site Data Sheets, or current on-demand, print-ready Water-Year Summaries.

Data Analysis Tools in the R Programming Language

USGS-R is a community of support for users of the R scientific programming language. USGS-R resources include R training materials, R tools for the retrieval and analysis of USGS data, and support for a growing group of USGS-R developers.

geoknife (R package)

The geoknife package was created to support web-based geoprocessing of large gridded datasets according to their overlap with landscape (or aquatic/ocean) features that are often irregularly shaped. geoknife creates data access and subsequent geoprocessing requests for the USGS’s Geo Data Portal to carry out on a web server.

USGS Water Web Services

This site serves USGS water data (streamflow, groundwater, water quality, site information, and statistics) via automated means using web services and extensible markup language (XML), as well as other popular media types. Services are invoked with the REST protocol. These services designed for high fault tolerance and very high availability.

Dissolved Solids Sources, Loads, and Yields For the Conterminous U.S.

Using the SPARROW (SPAtially-Referenced Regression on Watershed Attributes) model, long-term mean annual conditions for dissolved-solids sources, loads, and yields were predicted for nearly 66,000 stream reaches and their corresponding incremental catchments that drain the Nation.
