The USGS Active Groundwater Level Network includes about 20,000 wells that have been measured by the USGS or USGS cooperators at least once within the past 13 months. The animation shows a daily snapshot of water-level statistics in the network for January 2021.

The St. Mary and Milk Rivers cross the U.S. and Canadian border and supply water to both countries. Managing that resource in the interest of both nations is a matter of international collaboration and cooperation, and Landsat data is helping offer objective information on water use. On today’s episode of Eyes on Earth, we hear from Roy Sando of the USGS, who’s working

Map indicates groundwater sites within the USGS Active Groundwater Level network where the most recent groundwater-level measurement is in the 24th percentile or lower in the month of measurement over the period of record for the well.

This is an animation showing the changing conditions of USGS streamgages from October 1, 2020 to December 31, 2020. The river conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). A purple outer ring around a gage indicates it is flooding. As hurricane season came to a close, two final hurricanes made

Hydrologic Technician Matt Bach measures discharge in Ashwaubenon Creek near Little Rapids, WI (NWIS site: 04085068) on May 21, 2020, as part of a cooperative project with NEWWater (Green Bay Metropolitan Sewage District) utilizing an adaptive management approach to meet phosphorus

Katy O’Donnell monitors readings from different instruments of the flow-through system during a high-resolution water quality mapping survey onboard the RV Landsteiner along the Sacramento River in West Sacramento, CA. The flow-through system pumps water onto the boat while underway and directs sample water to a multiparameter water quality sonde, thermosalinograph,

Brian Bergamaschi and Katy O’Donnell onboard the RV Landsteiner during a high-resolution water quality mapping survey. The boat is equipped with a flow-through system that pumps water onto the boat while underway and directs sample water to a multiparameter water quality sonde, thermosalinograph, fluorometers, nitrate and ammonium analyzers. Data is logged every 1 second
