National Assessment of Coastal Vulnerability to Sea Level Rise

The original national coastal vulnerability index (CVI) assessment was motivated by expected accelerated sea-level rise (SLR) and the uncertainty in the response of the coastline to SLR. This research was conducted between 1999 and 2001, and is currently being updated using new data sources and methodology. This original study was part of the ...

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 Only 92,300 Mgal/d, or 27.3 percent of the water withdrawn, was consumptive use and thus lost to immediate further use; the...

Lake Meredith National Recreation Area takes its name from the water body it surrounds in the Texas Panhandle. The Amarillo-area lake sees more than a million visitors a year.

Visitor numbers were much smaller just a few years ago. More than a decade of drought shrank water levels at Lake Meredith until a rush of rain in 2017 brought a turnaround.
