Stacked bar chart of 1990-2019 agriculture, domestic, and industry freshwater withdrawals in the U.S., estimated by the World Bank. In all years, industry withdraws the most freshwater, followed by agriculture and domestic. From 2006 to 2010, industrial water dropped 5,000 cubic kilometers, then remained low.

Animation of five satellite images of the Tanana River in Alaska. The imagery is colored in shades of blue to show the degree of confidence that water is present. Two scatter plots show positive pairwise relationships between satellite river elevation and satellite river width and satellite streamflow.
