Seneca Falls, N.Y. - Environmentalists say an invasive plant poses a risk to the Finger Lakes.
Hydrilla was spotted last year in Cayuga Lake.
Thick mats of the plant can form, and eat up oxygen that other animals need to live.
Hydrilla can also clog up waterways and make them impassible for boaters and swimmers.
Cornell Cooperative Extension is sponsoring an information session on hydrilla later this month. The meeting, titled "Hydrilla's Threat to the Finger Lakes and What You Can Do" is scheduled for 7p.m. - 8:30 p.m. on June 13 at the Fayette Fire Department at 4200 Route 414 in Seneca Falls.
