On YouTube: Volunteers battle water chestnut growth in Oswego County
Coastal Community Development Program - News

A group of volunteers, including members of New York Sea Grant's Waterfront Launch Steward Program (pictured above, in red T-shirts), gathered in Oswego County Saturday morning to help battle an invasive species that has taken over several bodies of water in that area. YNN's Candace Hopkins shows us water chestnut, and the problems the weed creates.


Pulaski, NY, July 13, 2013 -  On first glance water chestnut looks like an average plant, but the invasive species has overtaken shorelines on both the Oswego and Salmon Rivers (as pictured below). Thick patches of it make boating nearly impossible, and it can damage the local ecosystem.



"It has a tendency to sprout, come up to the surface, and then it's just like taking a Venetian blind and pulling it across the water surface; it shades out and shadows out the sunlight. So, it prevents the sunlight from penetrating down and providing that additional warmth and growth to the vegetation," said Oswego County Soil and Water Conservation District Manager John DeHollander.

Last August Oswego County officials treated one area of the Oswego River with herbicide, hoping to wipe the water chestnuts out. And Saturday morning a group of volunteers gathered at the Pine Grove Boat Launch in Pulaski to do their part. They headed out in boats and kayaks to hand-pull the weed. It's a battle some of these residents, like Dick Drosse of Minetto, have been fighting for years.

"Basically with us living by the Battle Island area, they've had this infestation of the water chestnuts for quite a few years, and the mats have developed there. So, what we've done is gone out and found areas where you can do some hand-picking of the chestnuts," said Drosse.

Hand-pulling has been successful here, because the plant was attacked before it was able to spread. In addition to hurting the environment, local boat captains worry the problem could impact their fishing businesses.

"I mean, it affects us, even people that are full time guides or captains but even people that are just recreational boaters. I know there's one river in Oswego County that's become completely choked off. You couldn't get a boat with a motor up or down the river because it would just clog your prop," said Oswego County River Guides Association President Phil Bortz.

Now local officials hope the problem will get more attention, before it produces far-reaching consequences.

This is the third year of the event. Another pull will be held in Minetto in August. For more information on that event, you can contact Dick Drosse at 315-343-4565, or you can reach out to the Oswego County Soil and Water Conservation Department as well.
