Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Water use in the U.S., 2015

How do we use water in the U.S.?

We all depend on water every day, ranging from the water from our faucets, to the food we eat, to much of the electricity we use. The U.S. and its territories used nearly 322 billion gallons of water per day in 2015. This would cover the continental U.S. in about two inches of water over the course of a year. The national breakdown of...
