Interactive Maps

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. 

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.

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.

The Geo Data Portal (GDP) provides access to numerous datasets, including gridded data for climate and land use. Datasets can be subsetted or summarized before download using several algorithms, and these algorithms can also be applied to other datasets hosted elsewhere.

Since 2000, the Colorado River Basin has been experiencing a historic, extended drought that has impacted regional water supply and other resources, such as hydropower, recreation, and ecologic services. This visualization is part of a multi-agency effort to showcase the usefulness of open data by exploring the current 16-year drought and its effects on the Colorado River Basin.

The U.S. Geological Survey compiles water-use estimates every five years for each State, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. Archived datasets underlying the published "Estimated Use of Water in the United States" reports are available from the above link. County data incorporating any revisions can be found on NWISWeb.

Depth-to-water is measured periodically to evaluate hydrologic conditions at important aquifers throughout Puerto Rico. The water-level measurements from observation wells can be computed to understand the hydrologic stresses acting on aquifers and how these stresses affect groundwater conditions. 

Both the GOM Dashboard and the Sea-level Tool feature interactive maps for viewing either water data and associated weather data or the potential for flooding. Both maps are specific to regions along the Gulf of Mexico.

The Biomonitoring of Environmental Status and Trends (BEST) Program's Large River Monitoring Network (LRMN) has examined fish health in multiple river basins by using a suite of organismal and suborganismal endpoints, which monitor and assess the effects of environmental contaminants in fish.

This site provides hydrologic data collected or compiled by the USGS in the Yucaipa area; some additional data may be available from the USGS database National Water Information System (NWIS).

The Geologic CO2 Sequestration interactive web map includes investigated basins, assessed areas, stratigraphic columns, and well density information.

This website is a data visualization companion to the U.S. Geological Survey (USGS) report titled Federal Lands Greenhouse Gas Emissions and Sequestration in the United States: Estimates 2005-14. The maps and charts on this site include the estimated emissions and sequestration from both fossil fuel activities and ecosystem processes on Federal lands only.
