View recent monthly and daily groundwater levels in New England relative to long-term monthly statistics.

The U.S. Geological Survey (USGS) has partnered with North Carolina State University (NCSU), Louisiana State University (LSU) and University Corporation for Atmospheric Research (UCAR) to investigate hurricane-induced compound flooding and sediment dispersal using coupled hydrology and ocean models.

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.

The USGS is conducting research at uranium-bearing breccia pipe deposits to address data gaps related to the potential effects of uranium exploration and mining activities on the Grand Canyon watershed, its people, wildlife, and water resources. Study locations are primarily on Federal lands with a few locations on Tribal lands, and include historic and active mines.

This interactive map shares locations where per- and polyfluoroalkyl substances (PFAS) have been sampled by the Virginia and West Virginia Water Science Center in collaboration with partner agencies.

The Quaternary Fault and Fold Database of the United States database contains information on faults and associated folds in the United States that demonstrate geological evidence of coseismic surface deformation in large earthquakes during the past 1.6 million years (Myr).

The Lake Tahoe Hydro Mapper is web-based application that provides access to real-time and historical data for Lake Tahoe and surrounding areas.

A long string of Earth-observing orbiters began with NASA's Earth Resources Technology Satellite (ERTS). Launched in July 1972, it was the first satellite explicitly designed to study our planet. Three years later, the satellite was renamed Landsat 1. Outlasting its one-year design, Landsat 1 retired in January 1978.

After launch in 1975, Landsat 2 began to collect remote sensing data. Outliving its one-year design, Landsat 2 achieved seven years of operation. With two Landsats in orbit, scientists gleaned additional views of the planet. With this uninterrupted data, the record of the Earth's land surface could always be recorded, allowing for reliable imaging for scientists, policy makers, and land managers.

Although only two Landsats were originally anticipated, the program’s principal scientists sought to launch a third satellite for continued coverage because they found a wide variety of applications for the data. There was also interest in advancing the sensors and improving the data.

Landsat 4 was launched on July 16, 1982, with joint control of the program by NOAA, NASA, and the U.S. Geological Survey. Each federal agency took on a different role.

Landsat 5 remains the only Earth-observing satellite with a Guinness World Record , holding the title for "Longest Operating Earth Observation Satellite" after servicing our planet for nearly 29 years. Launched in 1984 and retired in 2013, Landsat 5 recorded many important events, including scientific discoveries, world events, and major disasters.
