September 24, 2013--Obama Administration moves to protect drinking water for millions of Americans (Water World)

The Obama Administration proposed a rule to restore protections to small streams and wetlands under the Clean Water Act (CWA) after those protections were eroded following two Supreme Court decisions. The ruling has been supported by some environmental organizations, inlcuding American Rivers.


November 16, 2012--How does groundwater pumping affect streamflow? (Science Daily)

Groundwater provides drinking water for millions of Americans and is the primary source of water to irrigate cropland in many of the nations most productive agricultural settings. Although the benefits of groundwater development are many, groundwater pumping can reduce the flow of water in connected streams and rivers -- a process called streamflow depletion by wells.


October 19, 2011--U.S. rivers and streams saturated with carbon (Science Daily)

Rivers and streams in the United States are releasing substantially more carbon dioxide into the atmosphere than previously thought, according to researchers publishing their results in the current issue of the journal Nature Geoscience. Their findings could change the way scientists model the movement of carbon among land, water and the atmosphere.


August 30, 2011--Get real-time data on floods and water flow at USGS' WaterWatch (USA Today)

As rivers leap out of their banks in New England in the aftermath of Irene, the U.S. Geological Survey provides a fascinating interactive site for real-time information on stream flows, generally updated on an hourly basis. WaterWatch provides maps that show the location of more than 3,000 long-term USGS streamgages, which show the amount of water flowing in streams and rivers.


Didymo Mystery Solved

According to research results published in the journal Geophysical Research Letters, the pristine state of unpolluted waterways may be their downfall.


April 28, 2011--President Obama seeks to extend Clean Water Act protections (Los Angeles Times)

More of the West's small streams and wetlands would be protected by the Clean Water Act under an Obama administration proposal announced Wednesday. The new guidance would replace policies of the President George W. Bush administration and clear up some of the legal murkiness created by two U.S. Supreme Court rulings that threw into question the reach of federal water pollution laws.


April 6, 2011--Biodiversity improves water quality in streams through a division of labor (Science Daily)

Biologically diverse streams are better at cleaning up pollutants than less rich waterways, and a University of Michigan ecologist says he has uncovered the long-sought mechanism that explains why this is so. Bradley Cardinale used 150 miniature model streams, which use recirculating water in flumes to mimic the variety of flow conditions found in natural streams.
