The East Columbia Basin Irrigation District (District) will be making aquatic herbicide treatments beginning in May 2024 and continuing through the end of the 2024 irrigation season.
These herbicide treatments will be made pursuant to a Department of Ecology Irrigation System
Aquatic Weed Control Permit (WAG991010).
The District’s service area is located in the Moses Lake, Warden and Othello areas of Grant and Adams Counties.
The District operates the East Low Canal and all laterals, drains and wasteways within the district’s service area. Treatments will be made when necessary to control the growth of algae, moss and pondweeds. Treatment frequency varies from as often as biweekly to as seldom as twice per irrigation season contingent upon weed conditions.
The pesticides being used for aquatic weed control are: Magnacide-H (acrolein), Copper sulfate, Aquatic Weed Killer (xylene), Captain and Captain XTR (chelated copper), Argos 8% (chelated copper), F-30 Algae Control (chelated copper), Clearcast, Cascade, and Teton (endothall). Water remains suitable for irrigation use during aquatic herbicide treatments. Treated water (and untreated water) is not suitable for drinking or swimming. Individuals desiring additional information about these treatments should contact the District’s main office in Othello at (509) 488-9671 and ask to speak to the Water Quality Supervisor.
Inquiries may also be directed to the Department of Ecology Headquarters, telephone (360) 407-7118, fax: (360) 407-6426.
