Stupid Policy that Endangers Species: Army Corps of Engineers Scorched Earth Levee Vegetation Removal
Posted on Aug 17, 2010 by Jennifer Lance.
Last summer, we reported about the Army Corps of Engineers plans to cut down trees along levees, even though their roots provide soil stabilization.

The Great Lakes have their shores full with issues around the invasive Asian carp, but that’s not the only danger facing the region. With 20% of the world’s freshwater, the health of the Great Lakes is critical- and this summer all of the lakes are registering temperatures far above what’s normal for the end of July. Lake Superior alone is estimated to be 10 to 15 degrees warmer than normal, and with another month of summer warming, experts think they could reach record-braking highs.

So it happened. The first Asian carp was found past the electric barrier designed specifically to keep them out of Lake Michigan. And the thing weighed 20 pounds.

WaterAlert: Customized, Real-Time Water Conditions
Posted on Jun 08, 2010 by Scott James.
For anyone who spends a lot of their time dealing with water, having up-to-the-minute information on water conditions is a tough proposition. Whether it’s a boater who wants current river level information, a groundwater manager who needs to know what pumps to keep working, or crisis management officials dealing with flood or drought conditions, having current information can be vital to safety. The USGS has created a system called WaterAlert that makes the information from all of the bodies of water across the country that they monitor available in real-time through text-message or email alerts.
