The USGS compiles water use information by State including estimated amounts, sources, and categories of use every five years since 1950. Sources include surface water and groundwater, both fresh and saline. Categories include public supply, domestic, livestock, industrial, irrigation, and thermoelectric power. These data provide a source of information about regional and national trends in...
Formation of arroyos in the late 1800s greatly increased erosion across the southwestern United States. Since the 1930s, however, this erosion has decreased, partly because of bank stabilization by introduced saltcedar. With Isleta Pueblo Indian Nation, the Aquatic Systems Branch developed a new sediment dating method using saltcedar tree rings. We applied the method in a landmark study of...
The USGS National Research Program (NRP), part of the USGS Water Mission Area, conducts research to develop and disseminate science-based information and tools needed for a fundamental understanding of the processes that affect the availability, movement, and quality of the Nation’s water resources. Our science supports a wide range of policies and activities.
Cooperative matching funds bring local, State, and Tribal water science needs and decision-making together with USGS national capabilities related to USGS nationally consistent methods and quality assurance; innovative monitoring technology, models, and analysis tools; and robust data management and delivery systems.
The National Water Census is a USGS research program on national water availability and use that develops new water accounting tools and assesses water availability at the regional and national scales. Through the Water Census, USGS is integrating diverse research on water availability and use and enhancing the understanding of connection between water quality and water availability.
Regional Groundwater Assessments provide objective scientific information and develop the interdisciplinary understanding necessary to assess and quantify the availability of the Nation's groundwater resources.
The U.S. Geological Survey's Water Use Science program is responsible for compiling and disseminating the nation's water-use data. USGS produces water-use information aggregated at the county, state, and national levels.
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.
At the National Water Census Data Portal you will find national estimates of water budget components for local watersheds, water withdrawal data for counties, tools to calculate statistics of daily streamflow records, modeled daily streamflow at ungaged stations, and access to records of aquatic biology observations.
The U.S. Geological Survey compiles water-use estimates every five years for each State, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. Archived datasets underlying the published "Estimated Use of Water in the United States" reports are available. Data incorporating any revisions can be found on NWISWeb.

In 1977, the Congress of the United States recognized the need for uniform, current, and reliable information on water use and directed the U.S. Geological Survey (USGS) to establish a National Water-Use Information Program (NWUIP) to complement the Survey's data on the availability and quality of the Nations water resources.
This video will provide a brief history and purpose for one of the oldest streamgages in Indiana. The gage is at the Wabash River at Lafayette, Indiana. The site number is 03335500. This video was produced at the request of the West Lafayette Parks Department where this historic gage is located. A QR code is displayed on an interpretive plaque next to the gage which is located in a high profile location within a city park adjacent to Purdue University. Park visitors can view a brief video on their smart phone which will educate them on the history of the gage and provide them with information on how to obtain current readings. The USGS WaterAlert text or email notifications is also featured. Our goal is to better educate the public on the importance of USGS streamgages in Indiana and the data we provide to the nation.

The new Great Salt Lake breach was opened on Dec. 1 by the Union Pacific Railroad Company. This created a new opening between the north and the south arm of the lake, allowing water to flow between the two sides. This time-lapse video shows the breach opening, which took about two hours. Before the new breach was opened, the north arm of the Great Salt Lake was at an historic low. Water had stopped flowing through the old Great Salt Lake causeway breach, preventing water to travel between the southern and northern portions. Water levels in the south arm were approximately 3.3 feet higher than the north arm when the breach was opened. The USGS will begin to monitor discharge through the new breech in cooperation with Utah Department of Environmental Quality. The USGS provides real-time lake elevation readings for both the north arm (Great Salt Lake near Saline, UT) and south arm (Great Salt Lake at Saltair Boat Marina, UT) of the Great Salt Lake. These gauging stations will be a valuable resource to observe the water level changes as the two portions of the lake combine and even out. The USGS maintains a record of Great Salt Lake elevations dating back to 1847 and has continuously measured the elevation of the lake since 1938.

As part of the assessment of the binational San Pedro aquifer, the effects of urbanization on runoff in ephemeral streams was studied. Ephemeral streams are those that flow in response to precipitation. Runoff in tributaries to the San Pedro River is important in understanding the water budget of the river. In addition, in arid watersheds such as the San Pedro, flow in ephemeral channels is potentially one of the most significant ways in which aquifers are recharged. To track runoff, we installed a network of 11 streamgages in ephemeral stream channels in and near Sierra Vista and Ft Huachuca, Arizona. The largest flow measured totaled nearly 70 acre-feet which is greater than the water contained in 1,000 14 ft x 34 ft backyard swimming pools, and we found that greater runoff occurred in the more urbanized stream.
