WaterWatch Toolkit
The USGS WaterWatch Toolkit provides online tools that allow users to search USGS sites in various ways; create a variety of maps, graphs, charts, animations, and tables; perform a variety of streamflow analyses, and retrieve summary statistics.
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.
USGS Water 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.
Flood Inundation Mapper
USGS Flood Inundation Maps, along with Internet information regarding current stage from the USGS streamgage, provide emergency management personnel and residents with information that is critical for flood-response activities, such as evacuations and road closures, as well as for post-flood recovery efforts.
Endangered, Discontinued, and Rescued Streamgages Mapper
This mapper identifies USGS streamgages that are in danger of being discontinued or converted to a reduced level of service due to lack of funding, gages that already have been discontinued, and gages that have been ‘rescued’ by a new funding source.
Science in Your Watershed
The Science in Your Watershed website helps you find scientific information organized on a watershed basis. This information, coupled with observations and measurements made by the watershed groups, provides a powerful foundation for characterizing, assessing, analyzing, and maintaining the status and health of a watershed.
National Environmental Methods Index (NEMI)
NEMI is a searchable database of environmental methods, protocols, statistical and analytical methods, and procedures that allows scientists and managers to find and compare methods for all stages of the monitoring process.
Estimated Annual Agricultural Pesticide Use
View the geographic distribution of Estimated Annual Agricultural Pesticide Use in the conterminous United States. A graph accompanies each map, which shows annual national use by major crop for the mapped pesticide for each year during the period.
Water-Quality Changes in the Nation's Streams and Rivers
This mapper provides results from the largest-ever assessment of water quality changes in the Nation's streams and rivers. More than 185 million water-quality records from over 600 Federal, State, Tribal, and local organizations were screened as part of this assessment.
Groundwater Quality: Decadal Change
Almost one-half of the U.S. population rely on groundwater for their water supply, and demand for groundwater for public supply, irrigation, and agriculture continues to increase. This mapper shows how concentrations of pesticides, nutrients, metals, and organic contaminants in groundwater are changing during decadal periods across the Nation.
GeoLog Locator
The USGS GeoLog Locator is a web-based tool that allows allows users to access more than 7,000 digital borehole geophysical logs and related data files at over 1,700 locations.
