Water chestnut eradication begins Aug. 5th

Local News

ONONDAGA COUNTY, N.Y. (WSYR-TV) — Beginning August 5th, the Onondaga County Health Department will use a herbicide to eliminate water chestnuts on the Seneca River in Baldwinsville and the Three Rivers area.

Water chestnuts are plants that are rooted in the river bottom and spread quickly. Their seeds can remain dormant for years, so water chestnut eradication can take years. Due to the way these plants grow, they can hinder navigation and crowd native plants.

The Onondaga County Health Department will be using a herbicide called Clearcast. The Health Department says, “Clearcast is considered safe for the control of vegetation in and natural bodies of water and noncropland sites. However, Clearcast is harmful if absorbed through the skin or inhaled and can cause moderate eye irritation. As a precautionary measure, we are asking the public to avoid the areas while they are being treated.”
