Data Access Tools

Search an archive of more than 500,000 still photographs, slides, glass plate slides, lantern slides, negatives, and sketches dating from the 1870s and taken by USGS scientists as part of their field studies.

Search the authoritative catalog for USGS peer reviewed scientific publications including USGS publication series, journal articles, books, book chapters, other government and nongovernment publications, cooperator publications, and conference proceedings.

Many USGS water-resource monitoring sites have webcams installed to allow remote visibility of current water and environmental conditions, identify technical issues, verify remote measurements, and gather data for visual analyses. The Hydrologic Imagery Visualization and Information System (HIVIS) provides access to still-frame images and timelapse videos from our active webcams.

We estimated food availability among five main wetland cover types used by overwintering American Black Ducks: subtidal, fresh water, high marsh, low marsh, and mudflat. Bioenergetics models used to inform North American Waterfowl Management Plan (NAWMP) can be simplified into two major components: energetic demand and energetic supply.

The Test Site Catalog contains information about worldwide radiometric, geometric, and spatial calibration sites used for post launch characterization and calibration of Earth observation sensors.

This application provides a set of interactive data visualization tools to explore datasets generated by USGS researchers for the RESTORE project. The purpose of this tool is to help stakeholders, decision makers and other interested users access these datasets and develop a better understanding of spatial and temporal streamflow patterns in the Lower Mississippi-Gulf Region.

The National Water Dashboard (NWD) is a mobile, interactive tool that provides real-time information on water levels, weather, and flood forecasts - all in one place on a computer, smartphone, or other mobile device. The NWD presents real-time stream, lake and reservoir, precipitation, and groundwater data from more than 13,500 USGS observation stations across the country.

WaterQualityWatch provides access to real-time water-quality data collected at more than 2,000 stream sites throughout the United States, including streamflow, water temperature, specific conductance, pH, dissolved oxygen, turbidity, and nitrate.

WaterWatch displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States, including flood and droughts. Real-time information generally is updated on an hourly basis.

The U.S. is sub-divided into successively smaller hydrologic units which are classified into four levels: regions, sub-regions, accounting units, and cataloging units. Each unit is identified by a unique hydrologic unit code (HUC) consisting of two to eight digits based on its classification. This site provides information and data for current and historical hydrologic units, names, and numbers.
