This past year has produced some record-breaking high streamflow conditions in the Northeast, as well as some near-record lows in other areas of the country, according to the U.S. Geological Survey (USGS). In a new USGS publication, "Streamflow of 2006--Water Year Summary," changes in streamflow over the course of 2006 are examined relative to conditions over the past 75 years.
This first-ever USGS summary of seasonal, regional, and national streamflow conditions for water year 2006 can be accessed at http://water.usgs.gov/waterwatch/2006summary/.
For more than 125 years, the USGS has monitored flow in selected streams and rivers across the U.S. The USGS collects data from more than 7,400 streamgages, many of which provide real-time data in 15 minute increments (explore this information at http://water.usgs.gov/waterwatch/). The information is routinely used for water supply and management, monitoring floods and droughts, bridge and road design, and for many recreational activities.
Access an even larger variety of USGS data, such as for ground water and water quality, through the National Water Information System Web Interface (NWISWeb), which contains over 1.5 million sites, and averages over 25 million hits per month (log onto at http://waterdata.usgs.gov/nwis/.
