The National Water-Use Science Project Active

By Water Resources February 22, 2019

The U.S. Geological Survey's National Water-Use Science Project (formerly the National Water-Use Information Program) is responsible for compiling and disseminating the nation's water-use data. Established by USGS in 1978, the USGS National Water-Use Science Project built on the legacy of the Estimated Use of Water in the United States report series, begun in 1950 and produced every 5 years.

The National Water-Use Science Project is a part of the National Water Census (NWC), which supports research focused on improving methods of collection and estimation of water-use data. Water use is a key component of the water-budget approach of the NWC.

Goals of the National Water Use Science Project:

  • Analyze the source, use, and disposition of water resources at local, State, and national levels
  • Reply to water-use information requests from the public
  • Document trends in water use in the United States
  • Cooperate with State and local agencies on projects of special interest
  • Develop water-use data bases
  • Publish State and national water-use data reports

A number of guidelines and methods reports are available for the USGS water-use compilations and related work, both for specific categories of water use and for more recent compilations as a whole.

Below are related water-use topics.

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...

Methods for estimating water consumption for thermoelectric power plants in the United States

Water consumption at thermoelectric power plants represents a small but substantial share of total water consumption in the U.S. However, currently available thermoelectric water consumption data are inconsistent and incomplete, and coefficients used to estimate consumption are contradictory. The U.S. Geological Survey (USGS) has resumed the estimation of thermoelectric water consumption, last don

Estimating irrigation water use in the humid eastern United States

Accurate accounting of irrigation water use is an important part of the U.S. Geological Survey National Water-Use Information Program and the WaterSMART initiative to help maintain sustainable water resources in the Nation. Irrigation water use in the humid eastern United States is not well characterized because of inadequate reporting and wide variability associated with climate, soils, crops, an

Description of 2005-10 domestic water use for selected U.S. cities and guidance for estimating domestic water use

Domestic water-use and related socioeconomic and climatic data for 2005-10 were used in an analysis of 21 selected U.S. cities to describe recent domestic per capita water use, investigate variables that potentially affect domestic water use, and provide guidance for estimating domestic water use. Domestic water use may be affected by a combination of several factors. Domestic per capita water use

Methods for Estimating Water Withdrawals for Aquaculture in the United States, 2005

Aquaculture water use is associated with raising organisms that live in water - such as finfish and shellfish - for food, restoration, conservation, or sport. Aquaculture production occurs under controlled feeding, sanitation, and harvesting procedures primarily in ponds, flow-through raceways, and, to a lesser extent, cages, net pens, and tanks. Aquaculture ponds, raceways, and tanks usually requ

Methods for Estimating Water Withdrawals for Mining in the United States, 2005

The mining water-use category includes groundwater and surface water that is withdrawn and used for nonfuels and fuels mining. Nonfuels mining includes the extraction of ores, stone, sand, and gravel. Fuels mining includes the extraction of coal, petroleum, and natural gas. Water is used for mineral extraction, quarrying, milling, and other operations directly associated with mining activities. Fo

Method for Estimating Water Withdrawals for Livestock in the United States, 2005

Livestock water use includes ground water and surface water associated with livestock watering, feedlots, dairy operations, and other on-farm needs. The water may be used for drinking, cooling, sanitation, waste disposal, and other needs related to the animals. Estimates of water withdrawals for livestock are needed for water planning and management. This report documents a method used to esti
