New Sightings Elsewhere in the U.S.

From February 19, 1992 (update #12)

HENNEPIN, Ill. - Seven mussels were found by Doug Blodgett of the Illinois Natural History Survey in late December attached to a substrate sampler placed at the LTV Steel plant located on the Illinois River near here, about 40 miles upstream of Peoria.

SYRACUSE, Ind. - Zebra mussels were sighted in two inland lakes near here last fall, according to David Heckaman of Sudlow's Pier Shop, Inc. Heckaman first found the mussels attached to a pier on Sept. 20 at the southeast end of Lake Wawasee in northeastern Indiana's Kosciusko County, not far from the Michigan border. He said hundreds of zebra mussels continued to be found throughout the fall at the southeast end of the lake near a state-owned boat launch ramp, and that the mussels could be found approximately 1.5 miles in any direction from this ramp. Heckaman also found a single mussel in November when a dock was removed from Eagle Lake in Cass County, Mich., not far from Lake Wawasee.

ROCKPORT, Ind. - Zebra mussels were found attached to pumps in onshore caissons in early January at an American Electric Power Company power plant near here, according to AEPC senior biologist Alan Gaulke. The plant draws its water from the Ohio River at river mile 745, about 40 miles upstream of Evansville, Ind. The mussels were spotted by a maintenance worker with an "intense curiosity" about zebra mussels, Gaulke said.

CUMBERLAND RIVER, Ky. - A single zebra mussel was found attached to a piece of wood at mile 67.5 of the Cumberland River during January, according to Tennessee Valley Authority officials. Doug Blodgett of the Illinois Natural History Survey reports that the TVA told him the sighting was not far from last September's sighting of a zebra mussel in Kentucky Lake, an impoundment on the Tennessee River.

CLARKESVILLE, Mo. - Several hundred mussels were found in early January attached to concrete walls and gates at Lock & Dam #24 on the Mississippi River near here, according to U.S. Army Corps of Engineers lock master Lewis Kent. The sighting was confirmed by Illinois Natural History Survey and U.S. Army Corps of Engineers experts.

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.
