The mechanical harvester in June collected huge amounts of the invasive water chestnut plants from the Res. But there were still some left that it couldn't reach. About thirty volunteers in canoes and kayaks with shore-side helpers collected 169 baskets of what remained. There are still more left though for future volunteer efforts. This event was organized by the Mystic River Watershed Association (MyRWA) and the Arlington Reservoir Committee. The water chestnut harvesting work is the responsibility of the Conservation Commission through its Water Bodies Working Group.
