The State DE- and volunteers spent Monday tackling an invasive weed that is choking out Otisco Lake.
Volunteers from the Otisco Lake Preservation Association spent the day Monday picking Water Chestnut from the lake.
Left unchecked the weed will crowd out natural habitats in the lake and for prevent swimming and boating.
The DEC say the manual effort is paying off over the last decade as biologists have seen a decline in the invasive plant. The first year of the program volunteers removed 35 boat loads of weeds. This year it was one boat load.
The plant can harm water quality in Otisco Lake.
