Integrated Water Science (IWS) Basins

The U.S. Geological Survey is integrating its water science programs to better address the Nation’s greatest water resource challenges. At the heart of this effort are plans to intensively study at least 10 Integrated Water Science (IWS) basins — medium-sized watersheds (10,000-20,000 square miles) and underlying aquifers — over the next decade. The IWS basins will represent a wide range of...

Next Generation Water Observing System: Illinois River Basin

The Next Generation Water Observing System provides high-fidelity, real-time data on water quantity, quality, and use to support modern water prediction and decision-support systems that are necessary for informing water operations on a daily basis and decision-making during water emergencies. The Illinois River Basin provides an opportunity to implement the NGWOS in a system challenged by an...

National Atmospheric Deposition Program (NADP)

The National Atmospheric Deposition Program (NADP) is a multi-partner atmospheric monitoring program that measures the concentrations and deposition of atmospheric constituents across North America. The USGS has been an NADP partner agency since 1981 and participates by providing funds for 82 National Trend Network (NTN) sites.

Atmospheric Warming, Loss of Snow Cover, and Declining Colorado River Flow

Declining snow cover is playing a key role in decreasing the flow of the Colorado River, “the lifeblood of the Southwest,” by enabling increased evaporation. As the warming continues, increasingly severe water shortages are expected.

Integrated Water Availability Assessments using Cooperative Matching Funds

A group of new projects from across the U.S. will help to support development of National and Regional Integrated Water Availability Assessments (IWAAs). They will be conducted with State and local partners with the support of Cooperative Matching Funds and will focus on improving the data, tools, and information stakeholders need to make water-resource management decisions.

Water Availability and Use Science Program: National Water Census

The USGS National Water Census (NWC) is designed to systematically provide information that will allow resource managers to assess the supply, use, and availability of the Nation’s water. The goal of the NWC is to provide nationally-consistent base layers of well-documented data that account for water availability and use nationally.

Water Use in the United States

The USGS works in cooperation with local, State, and Federal agencies to collect water-use information, then compiles these data to produce water-use information aggregated at the county, state, and national levels. Every five years, data at the county level are compiled into a national water-use data system and State-level data are published in a national circular, Estimated Use of Water in the...

USGS Flood Information

The USGS collects flood data and conducts targeted flood science to help Federal, State, and local agencies, decision makers, and the public before, during, and after a flood. Our efforts provide situational awareness, drive predictive models, inform infrastructure design and operation, undergird floodplain mapping, assist flood constituent/load quantification, and facilitate flood impact...

Total Water Use

The USGS has estimated water use for the United States every 5 years since 1950. Estimates are provided for groundwater and surface-water sources, for fresh and saline water quality, and by sector or category of use. Estimates have been made at the State level since 1950, and at the county level since 1985. Water-use estimates by watershed were made from 1950 through 1995, first at the water...

Surge, Wave, and Tide Hydrodynamics (SWaTH) Network

During large coastal storms, the storm surge and waves are the main cause of destruction and landscape change, transporting saline water, sediment, and debris inland. The USGS, in collaboration with stakeholders, has constructed a national Surge, Wave, and Tide Hydrodynamics (SWaTH) Network for the Atlantic, Eastern Pacific, and Central Pacific. SWaTH monitors and documents the height, extent, and...
