Interactive Maps

The Groundwater Conditions of Georgia web tool has interactive maps and graphs, that calculate water level trends over time. The application is a continuation of a series of reports begun in 1978.  

How wet was 2023 when compared to historical averages? This geonarrative compares precipitation and streamflow amounts observed during the 2023 water year with historical conditions in the Colorado River Basin over the last 30 years. While the 2023 water year was a wet year with above-average precipitation at many locations, it was not uniformly good or record-setting. 

To help resource managers plan and mitigate long-term drought impacts in the Colorado River Basin, the USGS has launched a platform that brings together science, data, and mapping and analytical tools from across the basin in a central location.

The Alaska Geochemical Database Version 4.0 (AGDB4) contains geochemical data compilations in which each geologic material sample has one “best value” determination for each analyzed species. Best values are for mineral exploration and assessment purposes and should not be assumed to be appropriate for other uses.

The U.S. Geological Survey National Produced Waters Geochemical Database Viewer (ver. 3.0) provides access to an updated compilation of geochemical and related information for water from oil and gas wells in the United States. The information includes identification and location information, well descriptions, dates, rock properties, physical properties of the water, organic chemistry and more.

This Web Tool explores the count of water bottling facilities across the U.S.

Facility types include bottled water facilities, breweries, distilleries, ice facilities, soft drink manufacturing plants, and wineries.

Reported volumes withdrawn (water use) for bottled water facilities are also explored for the small number of facilities for which data are currently available. 

This tool shows the presence of aquatic chlorophyll-a in select waterbodies. Note: This tool indicates the presence of aquatic chlorophyll-a and should not be used to determine if a toxic cyanobacterial bloom (harmful algal bloom) is present. 

This interactive map summarizes historical groundwater sampling for nitrate in the Albuquerque Basin, potential sources of nitrate in groundwater, and other complementary data.

The Baseflow Forecast Web Tool allows you to access baseflow forecasts at thousands of locations across the Nation.

This geonarrative is an interactive online presentation of the USGS Pennsylvania Water Science Center's data collection efforts related to Hurricane Ida. This geonarrative includes a summary of the storm in Pennsylvania, USGS data collection methods, embedded interactive maps of flood extents in 5 southeastern Pennsylvania localities, and visual depictions of the storm’s impact across the state.

This application is intended to help emergency, environmental, and public health managers at the federal, state, and local levels in West Virginia evaluate, plan for, and respond to potential drought conditions in at-risk communities. It uses estimated public water supply withdrawal rates to symbolize modeled drought conditions once every hour using National Water Model streamflow estimates.

For 50 years, the EROS Center has been archiving and distributing satellite, aerial, and mapping data amidst farmland north of Sioux Falls, South Dakota. We invite you to explore the surprising history and cutting-edge science and research performed at EROS every day.
