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
Lower Mississippi Gulf Water Science Center
The Lower Mississippi-Gulf multimedia gallery is a collection of images and videos that help vizualize our mission. We strive to provide first-class science and data to the public and our cooperators.
Each one these blue dots represents a site where a storm-tide sensor bracket has been installed for the Gulf of Mexico pre-defined network. There are currently 85 brackets in Florida, 6 in Alabama, 3 in Mississippi, 18 in Louisiana and 26 in Texas, for a total of 138 bracketed sites. (Not all brackets will be used in all storms.)
Groundwater use from the Ozark Plateaus aquifer system, 1900 to 2010” is a short video showing modeled groundwater withdrawal rates from the Ozark Plateaus aquifer system (Ozark system) in the central United States. The Ozark Plateaus Groundwater Availability Study aims to quantify current groundwater resources in the Ozark system, evaluate how these resources have changed...

Daniel McCay and Chris Henry, USGS hydrologic technicians, use a level to draw a line on a high-water mark August 26. In most circumstances, when a high-water mark is flagged it would then be surveyed with GPS equipment to obtain its exact coordinates and elevation. However, because of the possibility of more storms hitting Louisiana the teams were initially only...
