Total renewable freshwater resources

Where this number comes from

DerivedMedium confidence2022

Source: World Bank — World Development Indicators, World Bank WDI indicator ER.H2O.INTR.K3. Licence: Open — attribution required (attribution required).

Method: Renewable internal freshwater resources: the long-term average annual flow of rivers and recharge of groundwater generated from precipitation within the country. Internal resources exclude inflow from upstream countries, so this is the measure of self-sufficiency rather than of total availability. Originating body: FAO AQUASTAT.

Method: Renewable internal freshwater resources divided by population. Because the population denominator updates annually while the resource figure is a long-term hydrological average, movement in this series is largely population change rather than hydrological change. Originating body: FAO AQUASTAT and World Bank population estimates.

ReportedMedium confidence2022

Method: Total annual freshwater withdrawn for agricultural, industrial and domestic use. Withdrawal is not consumption: much of what is withdrawn is returned to the source catchment.

Method: Industrial withdrawal as a percentage of total freshwater withdrawal. Countries differ in whether thermoelectric cooling is counted here, and where it is the share reflects cooling arrangements rather than manufacturing intensity. Originating body: FAO AQUASTAT.

How water is used

Freshwater withdrawal by sector — United States

Share of total freshwater withdrawal. Withdrawal is not consumption: much of what industry and energy withdraw is returned.

Sector shares are reported for varying reference years by country, and countries differ in whether thermoelectric cooling is counted as industrial withdrawal.

Snow, as water

851 snow monitoring sites in United States report how much water is held in the snowpack. The seasonal shape below is from the longest record among them.

The snow year at Lick Creek

Typical and highest water content of the snowpack in each calendar month, across 1963–2026.

Typical month (median across the record)
Highest that month has been

Twelve separate statistics, one per calendar month, computed across the whole record rather than from any one year. A median August of zero is not a dry August: it is a site that has no snow in August in most years, which is why Hydrionis does not report a percentile for months a site spends on its floor.

Drought

The U.S. Drought Monitor publishes, every week, the share of United States its authors place in each of its severity categories. This is that record — an expert assessment, not a measurement, and not a legal declaration.

Share of United States in each drought category

Weekly, 2000–2026. Categories are cumulative as published: D2 or worse includes the area in D3 and D4.

D0 or worse — abnormally dry
D1 or worse — moderate
D2 or worse — severe
D3 or worse — extreme
D4 — exceptional

An expert assessment combining precipitation, soil moisture, streamflow, reservoir and snowpack indicators with reports from local observers. Being in a Drought Monitor category is not a statement that any authority has declared a drought or imposed a restriction. The figure is a share of land area, which is not the share of people, farmland or water supply affected.

Attribution you are required to give

These are conditions of the licences the underlying data is published under. They are obligations to the publishers, not to Hydrionis, and they apply to you directly whether or not you mention Hydrionis at all.

Suggested citation for Hydrionis

Hydrionis (2026), Water data for United States, accessed 2026-10-05, hydrionis.com/countries/united-states/

Cite Hydrionis where you rely on the compilation, the normalisation, the eligibility judgements or a chart. Where you use an unmodified published value, the publisher’s attribution is the one that is required; crediting Hydrionis as well is welcome and is not something Hydrionis can require of you.

Recommended, not required. Hydrionis does not claim rights over unmodified public data it relayed, and doing arithmetic on somebody else’s measurements does not make them Hydrionis’s. Cite the version and the access date: the United States record changes as publishers release and as methods are revised, and a citation without both cannot be checked later. Full guidance is on cite and reuse.

Hydrionis works to make data accurate, traceable and internally consistent through source validation, automated checks and documented methodology. Errors can still occur in original source data or in Hydrionis processing. For critical decisions, review the cited original source, the methodology and the known limitations. See accuracy and corrections.
