GLENWOOD  (AP) — Officials are investigating the report of a zebra mussel in Lake Minnewaska near Glenwood.

Lakeshore residents recently found what appears to be an adult zebra mussel attached to a boat seat mount that was submerged in the water. A Department of Natural Resources snorkeling crew surveyed the area, but didn't find other zebra mussels.

Officials are continuing to search the lake.

If zebra mussels are not immediately confirmed, more thorough surveys will be conducted this fall when boatlifts and docks are pulled from the water.

This would be the first zebra mussel infestation reported in Pope County. The DNR will designate Lake Minnewaska as an infested water and educational and enforcement efforts to limit the spread of invasive species will increase at the lake.
