The USGS produces national estimates of water withdrawal and consumptive water use. Withdrawal estimates are currently being finalized for a 20-year period from 2000 to 2020 for the three largest water use categories nationally (public supply, self-supplied thermoelectric power, and self-supplied crop irrigation). Six additional categories of use (self-supplied industrial, domestic, mining, livestock, aquaculture, and golf irrigation) will be available near the end of 2024.

The USGS works in cooperation with local, State, and Federal partners to compile and integrate water-use information with other datasets of climate, population, social, and economics in a modeling framework to produce national estimates of water withdrawal and consumptive use. Models allow for water use estimates to be available more frequently, data outliers to be identified more readily, and a means to consistently evaluate estimate uncertainty. Using methods that enhance understanding of what influences water use enables more informed forecasting of water use under different climate and social/economic futures.
Withdrawal estimates are being finalized for a 20-year reanalysis period from 2000 to 2020 for the three largest water use categories nationally (public supply, self-supplied thermoelectric power, and self-supplied crop irrigation). The estimates are for each month of that 20-year period for all watersheds at the 12-digit hydrologic unit code level in the continental United States. The public release of these withdrawal estimates is anticipated towards the end of 2023.
Six additional categories of use (self-supplied industrial, domestic, mining, livestock, aquaculture, and golf irrigation) will be available near the end of 2024, as the development of those models will be started in 2023. Furthermore, all models will be expanded to include Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands during this next phase of model development.
At present, the most recent water use estimates are from 2015.

National Water Census
The National Water Census will deliver routinely updated water availability information in the United States.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...Trends in Water Use
Total withdrawals for all categories of use in 2015 were estimated to be 322 billion gallons per day (Bgal/d), a level of withdrawal not reported since before 1970. Total withdrawals in 2015 were 9 percent less than in 2010, continuing a sharp but steady downward trend since 2005. Freshwater withdrawals were also 9 percent less than in 2015.Surface-Water Use
Surface-water sources include streams and rivers, lakes and reservoirs, and oceans. For the purposes of the USGS water-use reports, surface water with less than 1,000 milligrams per liter (mg/L) of dissolved solids is considered freshwater, and the remainder is considered saline.Surface-water resources are often evaluated by watershed. The most recent USGS water-use estimates by watershed are in...Groundwater Use
Groundwater refers to all subsurface water, specifically that part of groundwater which is in the saturated zone. Groundwater sources are called aquifers: geologic formations that contain sufficient saturated permeable material to yield significant quantities of water to wells and springs. For the purposes of the USGS water-use reports, groundwater with less than 1,000 milligrams per liter (mg/L)...Water-Use Terminology

Estimated use of water in the United States in 2015
Water use in the United States in 2015 was estimated to be about 322 billion gallons per day (Bgal/d), which was 9 percent less than in 2010. The 2015 estimates put total withdrawals at the lowest level since before 1970, following the same overall trend of decreasing total withdrawals observed from 2005 to 2010. Freshwater withdrawals were 281 Bgal/d, or 87 percent of total withdrawals, and salinFilter Total Items: 20Summary of estimated water use in the United States in 2015
A total of 322 Bgal/d of water withdrawals was reported for eight categories of use in the United States in 2015, which was 9 percent less than in 2010 (354 Bgal/d), and continued a declining trend since 2005. The decline in total withdrawals in 2015 primarily was caused by significant decreases (28.8 Bgal/d) in thermoelectric power, which accounted for 89 percent of the decrease in total withdrawSummary of estimated water use in the United States in 2010
About 355,000 million gallons per day (Mgal/d) of water was withdrawn for use in the United States during 2010, a decline of 13 percent from 2005 and a substantial change from the level of about 400,000 Mgal/d reported from 1985 to 2005. Withdrawals for 2010 were lower than withdrawals estimated for 1970. Fresh surface-water withdrawals (230,000 Mgal/d) were almost 15 percent less than in 2005, anEstimated use of water in the United States in 2010
Water use in the United States in 2010 was estimated to be about 355 billion gallons per day (Bgal/d), which was 13 percent less than in 2005. The 2010 estimates put total withdrawals at the lowest level since before 1970. Freshwater withdrawals were 306 Bgal/d, or 86 percent of total withdrawals, and saline-water withdrawals were 48.3 Bgal/d, or 14 percent of total withdrawals.

Estimates of water use at thermoelectric plants were developed by the U.S. Geological Survey based on linked heat and water budgets, and complement reported thermoelectric water withdrawals and consumption. The heat- and water-budget models produced withdrawal and consumption estimates, including thermodynamically plausible ranges of minimum and maximum withdrawal and consumption, for 1,290 water-Summary of estimated water use in the United States in 2005
About 410,000 million gallons per day (Mgal/d) of water was withdrawn for use in the United States during 2005. About 80 percent of the total (328,000 Mgal/d) withdrawal was from surface water, and about 82 percent of the surface water withdrawn was freshwater. The remaining 20 percent (82,600 Mgal/d) was withdrawn from groundwater, of which about 96 percent was freshwater. If withdrawals for therEstimated use of water in the United States in 2005
Estimates of water use in the United States indicate that about 410 billion gallons per day (Bgal/d) were withdrawn in 2005 for all categories summarized in this report. This total is slightly less than the estimate for 2000, and about 5 percent less than total withdrawals in the peak year of 1980. Freshwater withdrawals in 2005 were 349 Bgal/d, or 85 percent of the total freshwater and saline-watEstimated withdrawals from principal aquifers in the United States, 2000
Fresh ground-water withdrawals from 66 principal aquifers in the United States were estimated for irrigation, public-supply, and self-supplied industrial water uses for the year 2000. Total ground-water withdrawals were 76,500 million gallons per day, or 85,800 thousand acre-feet per year for these three uses. Irrigation used the largest amount of ground water, 56,900 million gallons per day, follEstimated Use of Water in the United States in 2000
Estimates of water use in the United States indicate that about 408 billion gallons per day (one thousand million gallons per day, abbreviated Bgal/d) were withdrawn for all uses during 2000.

Estimates of water use in the United States in 1970 indicate that an average of about 370 bgd (billion gallons per day)about 1,800 gallons per capita per day--was withdrawn for the four principal off-channel uses which are (1) public-supply (for domestic, commercial, and industrial uses), (2) rural (domestic and livestock), (3) irrigation, and (4) self-supplied industrial (including thermoelectricEstimated use of water in the United States, 1965
Estimates of water use in the United States for 1965 indicate that an average of about 310 bgd (billion gallons per day) were withdrawn for public-supply, rural domestic and livestock, irrigation, and industrial (including thermoelectric power)uses--that is, about 1,600 gallons per capita per day. This represents an increase of 15 percent over the withdrawal of 270 bgd reported for 1960. Fresh wat
