The North Unit Irrigation District (NUID) will begin applying aquatic herbicides to its irrigation canals beginning May 2026 and periodically as needed through October 2026.
The aquatic herbicide applications may include the following products: Copper Sulfate and Magnacide H with active ingredient Acrolein. The intended applications will control aquatic weeds and algae growth in canals within NUID boundaries.

Waters within the irrigation delivery system of NUID are intended for agricultural purposes. Customers are advised not to use the treated water for recreation, aquaculture, human or animal consumption.
Interested persons can call the NUID office at (541) 475-3625 to obtain more information and request to be notified in advance of treatments.
