The National Weather Service of the National Oceanic and Atmospheric Administration (NOAA) has launched the River Watch site, providing up-to-date river forecast information for the nation's largest river basins: the Mississippi, Missouri, Illinois, and Ohio River Basins). Daily river level summaries are provided for each basin, in addition to five-day forecasts for river stage heights (in feet). This site also offers hyperlinks to river forecast sites for the other major regions of the US (Southern, Central, and Eastern Regions), and other related sites. For current information on river level conditions in the US, this is a top-notch resource, made more valuable by the geographical extent of its coverage.
