Elsewhere in Wisconsin: No News is Good News

From June 14, 1991 (update #8)

GREEN BAY -- No zebra mussels were found in the City of Green Bay Water Utility intake in Lake Michigan north of Kewaunee during an inspection of their two intakes June 6-7. The inspections were performed in 30 feet of water by a contract diver at distances of 3,000 and 6,000 feet from the shoreline. The pipeline connecting their Kewaunee intake with the city of Green Bay is 27 miles long.

RACINE -- No zebra mussels were found during an inspection of a 250-foot-long dewatered section of concrete tunnel under Lake Michigan near here, according to Herb Schmidt, water treatment plant superintendent for the Racine Water Utility. The tunnel is located downstream from an area in which mussels were found in April. The only major difference between the two areas was that the "clean" section was downstream from the point at which potassium permanganate has been injected for the last 12 years to control taste and odor problems and serve as a coagulant for particulate material.

MILWAUKEE -- Divers found no signs of zebra mussels during inspections of offshore cribs at the lakebed entrance to the South Milwaukee and Oak Creek municipal water intakes in late May, according to Paul Lohmiller, an engineer with Larsen Engineers.

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.
