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.

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.

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

Provides access to more than 100,000 geologic maps and other types of geoscience reports and data published from the early 1800s to the present day, by the USGS, the State Geological Surveys, and hundreds of other organizations.

Both the GOA 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 America.

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.

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.

Hurricane Harvey approached the U.S. Gulf coast on August 25, 2017. The Hurricane Harvey Water Footprint data visualization shows the hurricane's impact on precipitation and streamflow.

Hurricane Irma, the most intense hurricane observed in the Atlantic in the last decade, approached the west coast of Florida on September 10th, 2017. This Hurricane Irma Water Footprint data visualization animates the hurricane's path, cumulative precipitation, and its impact on river gage height.
