MAYVILLE – Volunteers are invited to join in two major efforts this month to remove the invasive water chestnut from Chautauqua County waterways.

County Executive Gregory J. Edwards and County Watershed Coordinator Jeff Diers have announced a mass search for the aquatic weed at 8 a.m. next Saturday at the Stow Park landing of the Bemus Point-Stow Ferry.

“I encourage all available residents with access to boats, kayak and water boots to come out and help search for this invasive species before it establishes itself permanently in Chautauqua Lake,” Edwards said.

Meanwhile, the Jamestown Audubon Society is calling for volunteers to help in an effort that began in May to remove the plant from the Big Pond area at the Aububon Center & Sanctuary, 1600 Riverside Road, Jamestown. Aububon officials report that the plants are flowering and must be removed before they go to seed. Pulls are planned from 2 to 5 p.m. Sundays, 9 a.m. to noon Tuesdays and 5 to 8 p.m. Wednesdays for the rest of the month. For information, call 569-2345 or email
