Sea Grant staffers take new interactive watershed planning tool for a spin
November 6th, 2013 by Irene Miles
Staff members from six Great Lakes Sea Grant programs met at Purdue University last week to preview a new web-based tool that will help local planners make sustainable land use decisions. The two-day workshop gave Sea Grant specialists a chance to work through the tool’s four-step process and suggest changes before they start using it with planning groups and communities next spring.The Tipping Points and Indicators tool uses watershed data and cutting-edge research to show planners where aquatic ecosystems in their region are stressed by various factors to the degree that they are in danger of crossing a “tipping point,” triggering rapid and sometimes irreversible shifts in their functioning. With help from a Sea Grant facilitator, planners can use the tool’s interactive maps and simulators to specify important regional priorities, pinpoint specific land use practices that threaten ecosystem health, and test how further development, restoration, or conservation projects would help or hurt. Together with suggested policies, ordinances, and outreach efforts, these features help planners develop watershed management plans that prevent ecosystems from being degraded beyond repair.
The tipping points tool is part of a four-year project funded by NOAA and EPA and coordinated by Illinois-Indiana Sea Grant. Research and outreach partners include Purdue University, University of Michigan, Michigan State University, University of Minnesota Duluth, University of Windsor, the Great Lakes Environmental Research Laboratory, the Cooperative Institute for Limnology and Ecosystem Research, the Great Lakes Restoration Initiative, NOAA, and the Sea Grant Great Lakes Network.

In the news: Great Lakes lawmakers consider a ban on harmful pavement sealant
November 14th, 2012 by Irene Miles“Negative effects on fish and other aquatic animals include inhibited reproduction, fin erosion, liver abnormalities, cataracts and death, according to Geological Survey reports.Coal-tar sealcoat makes up about half of the PAHs in lake sediment, according to Environmental Science and Technology. It is why PAH levels have increased in the sediment of urban and suburban lakes since 2000 even when other major PAH producers, like power plants, have been decreasing emissions.”
Local water travels a long, long way
June 25th, 2012 by Irene MilesWatersheds are areas where water comes together and drains to a common place. In addition to the streams and rivers and creeks that we can see, though, watersheds encompass a huge range of pathways for water, and your nearby water supply might be part of a very large system that spans multiple states.
“Of course, obtaining sustainable development in town isn’t enough, in and of itself, to guarantee high quality, fishable and swimmable rivers and streams. Industry plays a part; utilities and waste water treatment plants play a part; sensitive farming, ranching, and/or timbering play a part, all in different proportions depending upon the particular watershed in question.”
