Hydrilla Treatment in Cayuga Lake

The U.S. Army Corps of Engineers applied a single treatment of Komeen to the shallow waters off of Stewart Park on August 13th 2018, a pin-point treatment of 20 hydrilla plants growing there. Testing afterwards indicates that at all times, regular water quality standards were maintained. For more information, check out the page on the right entitled “Cayuga Lake Hydrilla Treatment.” 

Who We Are, Where to Get Information & Report Possible Hydrilla Infestations: 

The Hydrilla Hunters is an informal, trained group of Cayuga Lake watershed residents working together to prevent takeover of our lake and creeks by the aquatic invasive plant, Hydrilla verticillata. We are affiliated with the Hydrilla Task Force of the Cayuga Lake Watershed. This newsletter provides information about hydrilla and its eradication on Cayuga Lake.

Lakefront Hydrilla Hunters Needed Around Cayuga Lake: 

Chemical treatments in 2011-2017 have shown to be a success. No hydrilla found in the Cayuga Inlet since 2015 and no hydrilla found in Fall Creek since 2016. The Hydrilla Task Force continues to develop and modify the management plan in order to combat the invasive plant.

The professional monitoring teams need the assistance of Hydrilla Hunters patrolling and reporting on lakefront properties and checking your boats and docks! YOU. Contact  to learn how to identify hydrilla, and get ready for the summer 2018 “hydrilla season.”

NEW – IMPROVED! Hydrilla I.D. Sheets Available: We are mailing (free) Hydrilla I.D. sheets, which include other lake plant look-a-likes for comparison, printed in high-quality color on clear plastic sheets. Please contact Hilary at   to obtain one or more copies for your use in watching for hydrilla along the lake and in the creeks. Thanks to the West Shore Homeowners Association for funding these detection tools and to Josh Teeter, NY State Parks, for conception and design!

How to Report Observed Hydrilla

Fill out the following google form if you suspect that you have seen hydrilla:

You will need to include your

  • Name 
  • Date of observed hydrilla
  • Location of observed hydrilla
  • At least one image of the plant is required

Photos of plant specimens are preferred to be close up against a light/white background.

One image should be close up of the plant -enough to count the number of leaves on the whorls (the “circle” of leaves coming off the main stem) and then a second image to show the edge of the leaves to better detect serrations (toothed).

Maximum file size that can be uploaded is 1 MB.

The same individual may submit multiple entries. After your first submission, you will receive a message that you have already submitted this form. That does not mean you cannot submit another.
