Efforts to Eradicate Hydrilla from Cayuga Lake Continue

  • / Updated:
  • Staff Report 

The push to eliminate hydrilla from Cayuga Lake is set to continue this summer with aquatic herbicide treatments in Wells College Bay.

Starting the week of June 24, the US Army Corps of Engineers, in partnership with the New York State Department of Environmental Conservation, will conduct seven fluridone treatments through August, with a possible chelated copper treatment in August. Signs will be posted at public access points during applications.


The Cayuga County Health Department will monitor water quality for drinking and public bathing. Results will be available on their website. There are no restrictions on drinking, fishing, swimming, boating, or domestic use of treated water, but it should not be used for sensitive plants or certain vegetables.

Hydrilla, an invasive plant from Korea, grows rapidly and forms dense mats that harm native plants and aquatic life.
