Map of the U.S. by state, showing total water withdrawals, 2015

Real-time flow meter installed on a center-pivot irrigation well in Mississippi County, Arkansas as part of a cooperative project conducted between USGS and the Arkansas Natural Resources Commission. The meter will measure water use for irrigation, providing data which will help improve water-use information in other locations as well.

Flooding in Soldier Pond, Maine, following rainfall and snowmelt that led to high water levels in the Fish and St. John Rivers in April and May of 2018. 

USGS field crews installed a temporary rapid deployment gage on May 2, 2018, at Soldier Pond in the Fish River to monitor flooding near Fort Kent in Maine.

Did you know that changes in the amount of water in aquifers cause small changes in Earth’s gravitational field? When the amount of groundwater in an aquifer changes, either by recharge or by discharge to surface water or wells, the gravitational acceleration at the land surface also changes.
