The Mystic River Watershed Association, based in Arlington, is holding this event to manage the health of this important local, natural resource.
Help remove an invasive plant, the water chestnut, 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 and shoes you don't mind getting wet.
