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
Water is one of the most important of Alabama's natural resources. Water is not only a vital component of human existence, it is critical to the overall quality of life. In order to protect and preserve this resource for future generations, we must have a baseline of information to make decisions. Decision and policy makers must know the answers to three fundamental questions: where is the...
In June, 2004, the Black Warrior - Cahaba Rivers Land Trust (Land Trust) was awarded a Brownfield Grant from the Region 4 US Environmental Protection Agency for 2005. The Land Trust will utilize funding from the Brownfield Assessment Grant program to perform assessment of sites which may have handled hazardous substances from former industrial or commercial activities. The Land Trust is...
The magnitude and frequency of floods are important factors in the design of bridges, culverts, highway embankments, dams, and other hydraulic structures near streams. Information on flood magnitude and frequency is also used in flood plain management and development, and in establishing flood insurance rates. The objective of this project is to develop improved methods and equations for...
The U.S. Geological Survey (USGS), in cooperation with the Louisiana Department of Transportation and Development (DOTD), has collected and published information on water withdrawals and use on a 5-year basis since 1960. The reports present information on withdrawals from ground- and surface-water sources for use in water supply, industry, power generation, rural domestic, livestock,...
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. Since 1985 site-specific water-use data for several categories have...

Simulated hydrologic response to climate change during the 21st century in New Hampshire
The U.S. Geological Survey, in cooperation with the New Hampshire Department of Environmental Services and the Department of Health and Human Services, has developed a hydrologic model to assess the effects of short- and long-term climate change on hydrology in New Hampshire. This report documents the model and datasets developed by using the...Bjerklie, David M.; Sturtevant, Luke P.
Hydrogeologic framework and groundwater conditions of the Ararat Basin in Armenia
Armenia is a landlocked country located in the mountainous Caucasus region between Asia and Europe. It shares borders with the countries of Georgia on the north, Azerbaijan on the east, Iran on the south, and Turkey and Azerbaijan on the west. The Ararat Basin is a transboundary basin in Armenia and Turkey. The Ararat Basin (or Ararat Valley) is...Valder, Joshua F.; Carter, Janet M.; Medler, Colton J.; Thompson, Ryan F.; Anderson, Mark T.
Use of flow cytometry and stable isotope analysis to determine phytoplankton uptake of wastewater derived ammonium in a nutrient-rich river
Anthropogenic alteration of the form and concentration of nitrogen (N) in aquatic ecosystems is widespread. Understanding availability and uptake of different N sources at the base of aquatic food webs is critical to establishment of effective nutrient management programs. Stable isotopes of N (14N, 15N) are often used to trace the sources of...Schmidt, Calla M.; Kraus, Tamara; Young, Megan B.; Kendall, Carol
Processing of next generation weather radar-multisensor precipitation estimates and quantitative precipitation forecast data for the DuPage County streamflow simulation system
The U.S. Geological Survey, in cooperation with DuPage County Stormwater Management Department, is testing a near real-time streamflow simulation system that assists in the management and operation of reservoirs and other flood-control structures in the Salt Creek and West Branch DuPage River drainage basins in DuPage County, Illinois. As part of...Bera, Maitreyee; Ortel, Terry W.
Nutrient and metal loads estimated by using discrete, automated, and continuous water-quality monitoring techniques for the Blackstone River at the Massachusetts-Rhode Island State line, water years 2013–14
Flow-proportional composite water samples were collected in water years 2013 and 2014 by the U.S. Geological Survey, in cooperation with the Massachusetts Department of Environmental Protection, from the Blackstone River at Millville, Massachusetts (U.S. Geological Survey station 01111230), about 0.5 mile from the border with Rhode Island. Samples...Sorenson, Jason R.; Granato, Gregory E.; Smith, Kirk P.
A conceptual framework for effectively anticipating water-quality changes resulting from changes in agricultural activities
Agricultural activities can affect water quality and the health of aquatic ecosystems; many water-quality issues originate with the movement of water, agricultural chemicals, and eroded soil from agricultural areas to streams and groundwater. Most agricultural activities are designed to sustain or increase crop production, while some are designed...Capel, Paul D.; Wolock, David M.; Coupe, Richard H.; Roth, Jason L.
PDEPTH—A computer program for the geophysical interpretation of magnetic and gravity profiles through Fourier filtering, source-depth analysis, and forward modeling
PDEPTH is an interactive, graphical computer program used to construct interpreted geological source models for observed potential-field geophysical profile data. The current version of PDEPTH has been adapted to the Windows platform from an earlier DOS-based version. The input total-field magnetic anomaly and vertical gravity anomaly profiles can...Phillips, Jeffrey D.

Hydrologic Technician, James Albrecht, from the North Platte Field Office making a measurement of discharge under ice using a Flowtracker acoustic velocity meter on a top-setting wading rod. The string going across the picture is a tagline, used for measuring distance across the channel so that he can note the location of the ice hole he is working in. Typically, the technician will drill...
Sometimes the whole is actually *less* than the sum of its parts. In this case, it turns out that cadmium and zinc, when combined in ratios like you'd see in the environment, they are actually less toxic to aquatic insects than adding up their individual toxicities. Read more:...
Two new streamgages recently installed by the U.S. Geological Survey in the cities of Greenfield and Elwood, Indiana will provide continuous, real-time streamflow and water level information in areas that have demonstrated a need for reliable flood warning and flood-related data.
