thumbnail Real-time Alerts for Flooding and Droughts across the Nation –Sign up for "Project Alerts" to keep up with USGS scientists as they respond to floods, droughts, and chemical spills. These "real time" notifications are official, and yet informal, and describe flood, drought, or water quality conditions across the country, as well as how USGS field crews are responding to the event. Stay up-to-date on flows in flooded streams, drought-depleted groundwater, water quality in a lake, stream, or well, and deployment of USGS storm surge sensors in anticipation of a hurricane. A link to the RSS feed and the web archive can be found at http://water.usgs.gov/alerts/. (Press release)


thumbnail New Google Maps Deliver Current Air Temperatures in Maine Linkable and scrollable maps show real-time air temperature for monitoring sites in Maine and links to view the air temperature charts for the last seven days. Popup boxes show the most recent stage and streamflow, the USGS site name and number, and a link for more data through USGS's NWIS Web home page.


thumbnail Stream bank erosion in south-central Alaska –USGS, in cooperation with the Alaskan Matanuska-Susitna Borough, tracked stream bank erosion along the Matanuska River, a braided, glacial river in south-central Alaska, showing impacts to property, roadways, and public facilities over the last 5 decades (USGS report). The study mapped river geomorphology and stream bank characteristics from the Matanuska Glacier to the mouth of the Matanuska River (about 65 miles), establishing erosion hazard information from 1949-2006.
