Zebra Mussel Summary

From January, 1995 (update #23)

Zebra mussels brought no major surprises during the last quarter of 1994. Since the publication of ZMU 22, adult mussels were discovered in only one additional inland Wisconsin lake - Silver Lake. There were no zebra mussels sightings this year in the Dairyland Reservoir on the Flambeau River. Fourteen months ago, Dairyland Reservoir was the site of the only previous inland zebra mussel sighting in Wisconsin, other than the Mississippi River. Elsewhere in the Great Lakes region, new sightings were reported from a handful of inland Michigan lakes, in one new inland Indiana lake, and in an Ohio quarry last summer. Several of these sightings were in watersheds previously uninfested by mussels. To date, zebra mussels have not been found in any inland Minnesota lake. According to surveys by the National Biological Survey and the U.S. Army Corps of Engineers the zebra mussel population rose dramatically in the upper Mississippi River last summer.

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.
