Water is one of seven science mission areas of the U.S. Geological Survey (USGS). Water's mission is to collect and disseminate reliable, impartial, and timely information that is needed to understand the Nation's water resources.Read Science Plan
The Water-Use Open Forum allows those involved in water-use data collection, data management, and regulation to communicate about challenges and solutions to water-use data issues, such as data collection, storage, QA/QC, analysis and data dissemination.
Static flood-inundation map libraries consist of maps that have been created in advance of a flood that are ready to be served through the Internet. Each library consists of a set of flood extent and depth maps developed for predetermined stream stage intervals (for example, a map for each one foot of stage). A user can view real-time or forecast stage data from a USGS streamgage or National...
StreamStats is a Web-based tool that provides streamflow statistics, drainage-basin characteristics, and other information for USGS streamgaging stations and for user-selected ungaged sites on streams. When users select the location of a streamgaging station, StreamStats provides previously published information from a database. When users select a site on an ungaged stream, StreamStats will...
The USGS collects, analyzes, and distributes data on a wide variety of water-related issues and resources. Much of our data is publicly available through the National Water Information System (NWIS), but additional datasets and analytical tools are also available.Access NWISWeb

This USGS Data Release represents the synthetic and real data from hydrologically diverse streams used to test the performance and limitations of the Two-tracer Ratio-based Mixing Model (TRaMM) which uses high-frequency measures of two tracers (A and B) and streamflow to separate total streamflow into water from slowflow and fastflow sources.
Stream water-quality characteristics provide scientists and water managers with a better understanding of the effects of natural and anthropogenic (human) activities on streams and ecosystems. The USGS operates a network of near-real-time water-quality monitoring stations that provide data for temperature, specific conductance, pH, dissolved oxygen, and turbidity of surface water.
Electrical Conductivity Data for the Snake River, Yellowstone National Park and Grand Teton National Park
The U.S. Geological Survey (USGS) and the National Park Service (NPS) have collaborated on monitoring the chloride flux in the major rivers of Yellowstone National Park by periodically sampling the rivers and analyzing chloride concentrations in discrete water samples since the 1970's. However, restrictions of winter travel, great distances between sites, and sampling and analytical costs have...

Scientists are expecting that this year’s Chesapeake Bay hypoxic low-oxygen zone, also called the “dead zone,” will be approximately 1.37 cubic miles – about the volume of 2.3 million Olympic-size swimming pools. While still large, this is 10 percent lower than the long-term average as measured since 1950.
