National water summary 1987: Hydrologic events and water supply and use
Water use in the United States, as measured by freshwater withdrawals in 1985, averaged 338,000 Mgal/d (million gallons per day), which is enough water to cover the 48 conterminous States to a depth of about 2.4 inches. Only 92,300 Mgal/d, or 27.3 percent of the water withdrawn, was consumptive use and thus lost to immediate further use; the...

A growing number of wildfire-burned areas throughout the western United States are expected to increase soil erosion rates within watersheds, causing more sediment to be present in downstream rivers and reservoirs, according to a new study by the U.S. Geological Survey.
A carbonatite here, a glacial moraine there, a zig-zagging fault or two, even a behemoth of a batholith. The geology of the 50 States is an enormous patchwork of varied forms, beautiful in their variance but challenging to present as a single map.
