Water Chestnut Pull

The invasive water chestnut (Trapa natans) creates dense, floating mats that choke waterways, devaluing waterfront properties and disrupting local ecosystems. However, these populations can be effectively managed by manually harvesting their floating rosettes and seeds.

Key Impacts & Solutions
Environmental Damage: Aggressive growth alters delicate aquatic habitats and displaces native species.
Economic & Social Toll: Thick mats obstruct boating and swimming while dragging down property values.
Management Strategy: Manual removal of the rosettes and nutlets serves as a primary method for suppressing spread.

Save The River has worked with SLELO PRISM and the NYS Dept of Environmental Conservation for many years with removal efforts on Lake Ontario and in the watershed regions of the St. Lawrence River.  

Join Save The River for our annual Water Chestnut Pull in Guffin Bay, Dexter, NY, on Friday, August 7, 2026!

What to Expect: Using a kayak or canoe to paddle around a given area to collect the floating rosettes and nutlets of water chestnut and bring them ashore to be disposed of.
