Help remove an invasive plant from the Mystic River! Volunteers will head out in canoes to hand-pull water chestnut from the river or stay on land to help put the chestnuts in the dumpster to be composted. All supplies are provided. Bring sunblock, shoes you don't mind getting wet and a water bottle.

The volunteer event will be held at 100 Auburn St., Medford (across from Whole Foods on Route 16 in Medford). The event starts at 9:00 am and runs until 12:00 pm, followed by a pizza lunch.
