It's time to celebrate Grand Calumet River and Roxana Marsh cleanup In northwest Indiana, life may just be a little more hopeful than it used to be. The Great Lakes Legacy Act (GLLA) project to remove contaminated sediment from portions of the Grand Calumet River and adjacent Roxana Marsh is done. Unlike before the cleanup, these waterways will now likely attract birds, aquatic life, and people. “This river was lifeless,” said Cameron Davis, senior advisor on the Great Lakes to EPA Administrator Lisa Jackson. “Today, because of this effort, you can see the Grand Cal working and fighting to come back to life, and with it, the community.” A celebration and press event in June to mark this moment brought together many play- ers and partners involved in the process. And, thanks to work done by Caitie McCoy, Illinois-Indiana Sea Grant (IISG) social scientist, local school children capped off their semester-long learning expe- rience about the restoration project by planting native seedlings along the marsh’s shores. “Legacy Act projects provide oppor- tunities for residents to get involved in the river restoration process and learn about local water issues,” said McCoy. “As the Grand Cal project moved for- ward we have been ensuring that this includes local students too.” McCoy and Nishaat Yunus, a fellow in the U.S. EPA Great Lakes National Program Office (GLNPO), worked closely with students in two northwest Indiana schools, engaging them in Bringing AIS information to Page 2 hands-on water monitoring activities and other boat ramps learning opportunities.

And this can depend on where they live. including yellow perch, mottled sculpin, longnose sucker, and various invertebrate prey, have declined. University of Illinois graduate student Austin Happel studied the diet of juvenile yellow perch. He found “Our objective is to describe the nearshore food web that those on the rocky structure and how this varies with location, season, western shores along and bottom substrate,” said Czesny. “We are also Illinois and Wisconsin interested in how invasive species interact with native have a healthy diet of biota, which will ultimately help us manage this unique invertebrates whereas ecosystem that is Lake Michigan,” added Czesny. perch on the sandy east Courtesy of Austin Happel side have a skimpier diet The larger results of the study are still to come, but of zooplankton. smaller aspects of the project, such as Happel’s work with yellow perch, are beginning to tell a story.

Stable isotopes provide a picture of an even longer time frame.” “All these approaches have unique advantages, which, when combined, provide detailed informa- tion on the nearshore food web structure,” said Sergiusz Czesny, Lake Michigan Biological Station director.

Students took water samples to monitor water quality in restored sites— the results were shared with EPA and GLLA project partners. The students have gone back to the river to view progress on the restoration project. They have also learned data analysis, data reporting, and how scientists use data to make project-level decisions. At the East Chicago Lighthouse Charter School, about 50 fourth grade students from Andrea Bock's science classes grew native plants, provided by EPA. These plants were brought to Roxana Marsh to put in the ground as part of the celebration. McCoy and Yunus engaged students in key concepts associated with habitats and restoration projects. The children de- signed their own Roxana Marsh habitat by construct- ing a colorful classroom mural. McCoy is working with IISG’s education team— Robin Goettel and Terri Hallesy—to package the classroom programming developed through these efforts. This programming will be ready to apply at other GLLA sites, hopefully in conjunction with Sea Grant programs in other states. Altogether, more than 600,000 cubic yards of polluted sediment were remediated from 2.5 miles of the Roxa- na Marsh and Grand Calumet River. The project’s $52 million cost was shared by U.S. EPA and the state of Indiana. But there are many players in this project— EPA GLNPO, the U.S. Fish and Wildlife Service, the Indiana Department of Environmental Management, the Indiana Department of Natural Resources, the U.S.
