Inland Lake Sighting

From June, 1994 (update #21)

Given the high volume of boat traffic between infested and uninfested inland waters, the overland spread of zebra mussels may have proceeded more slowly than has been generally acknowledged. University of California-Santa Barbara's Ladd Johnson and the author of this publication have prepared a list of eight zebra mussel-infested inland lakes which required overland transport for colonization. We have only included lakes reported to contain populations of adult mussels. They are: Eagle, Loon and Portage lakes in Michigan; Lake Wawasee in Indiana; White Star Quarry and Hargus Lake in Ohio; and Conesus Lake and Hinkley Reservoir in New York. This list excludes New York's "Finger Lakes," the drowned river mouths of western Michigan, and lakes on the Trent-Severn Canal or Rideau Canal systems in Canada, all of which have navigable connections with infested waters of the Great Lakes and nearby waterways. We invite additions or corrections to our list. Johnson can be reached at (805) 893-7295; Kraft at (414) 465-2795, or via email at KRAFTC@UWGB.EDU.

The Zebra Mussel Update was a 4- to 8-page quarterly national newsletter published by the University of Wisconsin Sea Grant Institute from May 1990 through May 1997. The ZMU documented the spread of the zebra mussel -- an exotic nuisance mussel -- through North America's freshwater environments, especially the Great Lakes, and on efforts to control it.
