AQUATIC TREATMENTS
Aquatic Treatments
Sunnyside Valley Irrigation District will be continuing its aquatic weed treatment program to control aquatic plants and algae in our irrigation conveyance system. The District will be applying aquatic herbicide chemicals under a Department of Ecology NPDES and SWD General Permit.
Treatments made with Acrolein (Magnicide H), are labeled as being toxic to fish. If you use your irrigation water for fish rearing, you are advised to discontinue using the irrigation water, beginning on the day of treatment and for at least two days thereafter.
We will also be treating with Cascade and/or Teton (Endothall). If you do not wish to use treated water for any reason, you are advised to discontinue using the irrigation water, beginning on the day of treatment and for at least two days thereafter.
Treatments made with copper are labeled as being toxic to fish. If you use your irrigation water for fish rearing, you are advised to discontinue using the irrigation water, beginning on the day of treatment and for at least two days thereafter.
Aquatic herbicides will be applied by licensed SVID personnel. The SVID main office can be reached at (509) 837-6980 if there are any questions.
The Washington State Department of Ecology contact is the Central Regional Office at 1250 Alder Street in Union Gap, WA 98903, and can be reached at (509) 575-2490.
Below is the list of scheduled treatments.
