USGS Flood Event Viewer
During large, short-term events, the USGS collects streamflow and additional data (including storm tide, wave height, high-water marks, and additional sensor deployments) to aid in documenting flood events. The USGS Flood Event Viewer provides convenient, map-based access to downloadable event-based data.
Federal Priority Streamgages (FPS) Mapper
This mapper identifies USGS Federal Priority Streamgages (FPS). FPS are monitoring stations that track the amount of water in streams and rivers across the Nation to meet long-term federal information needs. They are strategically positioned to serve as a backbone for the larger National Streamflow Network that is operated in cooperation with over 1,200 federal, state, tribal, and local agencies.
Mississippi Alluvial Plain: Regional Geophysical Survey
The USGS Mississippi Alluvial Plain (MAP) Regional Water Availability Study began airborne geophysical mapping to obtain high-resolution information about the hydrogeologic structure and properties of the aquifer. This geonarrative showcases the geophysical data collected in this effort and provides a three-dimensional view into the Mississippi Alluvial Plain subsurface.
Expanding Pacific Exploration and Research: Overview of the EXPRESS research campaign
A multi-agency team is mapping uncharted waters and exploring deep-sea ecosystems off the west coast of the United States.
Oceans cover 71% of the Earth's surface, yet little is known about these vast underwater worlds. Less than 20% have been explored. A global initiative seeks to change that, by pledging to complete detailed mapping of one-hundred percent of the seafloor by the year 2030..
USGS Science and Technology Help Managers Battle Invasive Carp: A Geonarrative

From Snow to Flow (data visualization story)
A majority of the water in the western U.S. comes from snowmelt, but changes in the timing, magnitude, and duration of snowmelt can alter water availability downstream. This data visualization story explores what changing snowmelt means for water in the West, and how new USGS efforts can advance snow science by modeling snowpack and snowmelt dynamics and linking these results to streamflow.
Multisource Water-Quality Trends in the Delaware River Basin
Water quality is essential for understanding water availability by providing insights into the drivers of change and possible availability constraints. Using data from eight monitoring organizations including the USGS, the Multisource Water-Quality Trends in the Delaware River Basin mapper shows changing water-quality trends from 2008-2018 in rivers and streams across the Delaware River Basin.
North American Bat Monitoring Program (NABat) Partner Portal
NABat is an international and interagency program that aims to conserve North American bat populations by providing standardized survey data from across the continent.
Mercury in Freshwater Fish of the Chesapeake Bay Watershed—Story Map
The US Geological Survey (USGS), working with the partners in the watershed, compiled mercury data for freshwater fishes to understand how mercury concentrations, and risk to consumers, varies across the watershed.
Data Query for the Water Quality of San Francisco Bay Project
Since 1969, USGS has collected water-quality data along the deep-channel longitudinal axis of the San Francisco Bay-Delta system at 37 fixed locations spaced 3-6 kilometers apart. The Water Quality of San Francisco Bay Data Query provides access to the entire dataset.
