Mechanical Harvesting Removes Water Chestnut on the Charles River

The Charles River Watershed Association and local citizens have obtained funding to conduct large-scale mechanical harvesting to remove roughly 50 acres of water chestnut and other invasive weeds.

The Charles River Lakes District in Massachusetts is a popular destination for canoeists, kayakers and rowers, but the pollution from stormwater runoff resulted in an increase in nutrients resulting in the growth of water chestnut, Eurasian watermilfoil and fanwort which interfered with those activities.

The weed harvesters have will harvest for a few weeks in August before the water chestnuts drop their seeds and will start up again in the spring of 2014.

Water Chestnut Spreads in New York and Harms Aquatic Ecosystems and Recreation

Trapa natans is native to Western Europe and Africa and northeast Asia, including eastern Russia, China, and southeast Asia to Indonesia. Trapa natans was first introduced to North America in the mid- to late-1870s, when it is known to have been introduced into the Cambridge botanical garden at Harvard University around 1877.

A decade later later, the aquatic invasive species made its way to New York and now stretches fro Long Island, inland to the Hudson River Valley and up to Lake Champlain and is spread throught the Finger Lakes.

The water chestnut most directly impacts aquatic ecosystems by blocking sunlight from penetrating the water and preventing other aquatic vegetation from photosynthesizing. At the same time, the water chestnut photosynthesizes at the surface, restricting oxygen exchange under its cover. Other aquatic life, particularly fish, can be sensitive to low-oxygen environments. For the recreationist, water chestnuts make boating, fishing and swimming a crowded feat.
