Quick Link to Real-Time Data   ( Quick look: Real-time data typically are recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events. Data from real-time sites are relayed to USGS offices via satellite, telephone, and/or radio and are available for viewing within minutes of arrival.

USGS Mississippi Data Highlights

USGS Flood Inundation Mapper

Floods are the most common and widespread of all natural disasters in the United States and are the leading cause of weather related deaths. Advances in technology have improved warning systems and have helped to decrease the loss of life over the past 50 years. Several sources of information are available to citizens and public officials to help make timely decisions regarding flood awareness and flood loss mitigation. One recently developed source of information is the USGS Flood Inundation Mapper.

Digital maps are displayed through the interactive web mapper, and details of the project and modeling process are available in an online report. The availability of these maps, when combined with real- time stage information from USGS streamgages and forecasted stream stage from the National Weather Service, provides emergency management personnel and residents with critical information during flood-response activities, such as evacuations and road closures, as well as for post-flood recovery efforts.

2012 Mississippi Water Data Report Now Available

The 2012 USGS Water Data Report is now available online and improves on the previous online reports with a new interactive feature designed to make site data retrieval easier and more convenient.

The new report includes a national map interface that can be used to identify an area of interest, locate sites where water data were collected for Water Year 2012, and access most of that data. The annual Water Data Report provides a snapshot of water conditions for a given year. Access the Water Data Report using a text ( ) or map ( ) interface.

National Water Information System: Mapper

The new NWIS Mapper provides an interactive map interface to all USGS water data (historical and current). (Note: To access data, zoom in on the map to level 11 or greater to make the individual sites clickable.)

Instantaneous Data Archive (IDA)

The Instantaneous Data Archive makes available as much intra-day streamflow data and historical instantaneous data continuous (measurements from every 5 to every 60 minutes), as possible, often several years' worth of data.

Informative Tools & Links

USGS StreaMail

USGS StreaMail is a system for accessing real-time river stage and streamflow from hand-held wireless devices, such as cell phones and Blackberries. All you have to do is send an email or text message to "streamail@usgs.gov" and use a USGS station number in the "Subject" line. In a few minutes you'll get back an email/text message with the most recent stage and streamflow.

USGS WaterAlert

Now you can receive instant, customized updates about water conditions by subscribing to WaterAlert, a new service from the U.S. Geological Survey. WaterAlert allows users to receive updates about river flows, groundwater levels, water temperatures, rainfall, and water quality at more than 9,500 sites where USGS collects real-time water information. The Mississippi Water Science Center collects real-time water information at more than 130 sites throughout Mississippi and makes that data available to the public through WaterAlert.
