Document Summary

Changes in the lake: water has become clearer as the quanity of pariculate mater in the water column has been greatly reduced. This is one of the byproducts of the huge abundance of zebra mussels, whose ilter-feeding aciviies cycle massive amounts of water every day. The beach does not show other signs of zebra mussel infestaion, but the dock is covered in zebra mussels below the water line. One can witness the efects of zebra mussels even while on vacaion on georgian bay and lake. Dr. gregory saw how abundant zebra mussels could be, and how this can impact our enjoyment of lakes. The fact that they are able to atach to just about any solid surface has made them a real menace as they clog pipes and cover industrial equipment, docks, and boats. The economic damage by zebra mussels and the eforts to control them have already cost billions.
