From June 14, 1991 (update #8)

CATSKILL, N.Y. -- Zebra mussels took a giant step out of the Great Lakes basin into the Hudson River basin in late May, when they were discovered in the vicinity of the Rip Van Winkle Bridge near here, according to New York Sea Grant coastal resources specialist Charles O'Neill. This sighting is the first confirmed sighting of zebra mussels in the United States outside of the Great Lakes basin. Catskill is about 30 miles south of Albany, N.Y., and 100 miles upstream of New York City.

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.
