In response to recent harmful algal blooms (HABs) that have occurred in many of the large water storage reservoirs in the Willamette River Basin the USGS is measuring related water-quality parameters in Detroit Lake and Blue River Lake. The USGS has also developed profiler tools that allow users to see how the water quality parameters vary with depth in those reservoirs.

The USGS provides information and tools needed to help solve problems posed by invasive species across the country. Key components of USGS invasive species science include developing novel prevention, forecasting, early detection, decision support, and control tools.

USGS Scientists published a StoryMap showing projected changes in land use, flooded area, and wildlife habitat in California’s Central Valley for five scenarios of future climate and water management.

USGS scientists published a storymap explaining the impacts of sea-level rise on liquefaction severity around the San Francisco Bay Area, California for the magnitude 7.0 ‘HayWired’ earthquake scenario along the Hayward Fault.

Displaying water-quality data with depth over time at a single location has always presented a challenge. These data visualizations were developed as a response to that issue by Katherine Jones, USGS Office of Quality Assurance.

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.

This geonarrative provides an overview of Mauna Loa’s eruptive history and hazards and includes interactive maps and datasets to help residents prepare for the next eruption.

The Arctic Rivers Project will weave together Indigenous knowledges, monitoring, and the modeling of climate, rivers (flows, temperature, ice), and fish to improve understanding of how Arctic rivers, ice transportation corridors, fish, and communities might be impacted by and adapt to climate change.

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.

The U.S. Groundwater Conditions animated data visualization depicts groundwater levels at 2,281 well sites across the U.S. At each site, groundwater levels are shown relative to the historic record (using percentiles), indicating where groundwater is comparatively high or low to what has been observed in the past. The corresponding time series chart shows the percent of sites in each water-le
