Oh Buoy, Missed Mussels Found

From April 30, 1991 (update #7)

CHARLEVOIX, Mich. - Dozens of small mussels were discovered in crevices on a navigation buoy from the Calumet Harbor, Ill., area as it was being prepared for service this spring, according to U.S. Coast Guard Lt. Cmdr. P.L. Hawkins. Calumet Harbor is near the boundary of the Lake Michigan and Mississippi River basins. The Coast Guard originally had reported finding no mussels on buoys decommissioned from southern Lake Michigan last fall.

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.
