    EAST LANSING, Mich. -- Zebra mussels are now infesting Michigan's
10th largest inland lake and, for the first time, two lakes in the Upper
Peninsula.  Higgins Lake (Roscommon County), Antoine Lake (Dickinson
County) and Fortune Pond (Iron County) were among the 16 lakes
confirmed infested for the first time in 2001, according to Michigan
Sea Grant.

 The total number of confirmed infested lakes stands at 165, an
11 percent increase over the 149 lakes listed in 2000.  Six of the
state's 10 largest lakes are now infested.

 In 2001, volunteers found the invasive species in lakes in the
following counties:  Antrim (Birch), Branch (Lake of the Woods), Cass
(Finch, Long), Dickinson (Antoine), Iosco (Long), Iron (Fortune Pond),
Lapeer (Nepessing), Livingston (East Crooked, Orr, Sandy Bottom),
Muskegon (Big Blue), Oakland (Angelus, Crescent, Greens) and Roscommon

 All of last year's reports came from lakefront property owners and
resource managers who found adult colonies of the mussels clinging to
boats, docks, dams, water pumps and equipment.  Twenty-five percent of
the reports came from participants in the Brick Watch program,
initiated in 2000 by Michigan Sea Grant, Michigan Lake and Stream
Associations (ML&SA), and the Michigan Department of Environmental

 Sea Grant Extension specialist Mike Klepinger said citizen
monitoring, especially for adult zebra mussels, has dramatically
increased scientists' knowledge and understanding of how and why
invading organisms spread once they arrive in the Great Lakes basin.

Citizen participation in monitoring has gradually increased the number
of lakes surveyed and the accuracy of surveys on individual lakes,
providing early detection of zebra mussel populations and helping
prevent damage to boats, beaches and lake ecosystems.

 "Inland lakes with a high level of transient recreational boating
activity due to their large size and public access and those in close
proximity to infested waters are particularly vulnerable," Klepinger

        Zebra mussels can contaminate lakes when boaters and anglers
unknowingly transport the clinging veligers (immature mussels) from
infested waters via boats, trailers and fishing equipment.  Early
detection allows lake managers and citizen groups to erect signs at
boat launches and develop volunteer programs for boat inspections and
cleanings.  It also lowers the incidence of unwitting movement to
neighboring lakes.

 Organizations and individuals interested in participating in Brick
Watch should contact ML&SA's Pearl Bonnell at (989) 257-3583.  For more
information about citizen lake monitoring and zebra mussels, including

        ML&SA is a statewide organization of more than 375 local lake and
stream associations.  Michigan Sea Grant is a cooperative program of
Michigan State University and the University of Michigan in Great Lakes
and marine research, education and outreach.
