West Extension Irrigation District will be applying the aquatic herbicide “Argos” (liquid chelated copper) in its Main Canal over 2 days::

Wednesday, June 29, 2022 (2 treatments): Upper Canal (Phase 1 Inlet (East of Power Line Road) to Division) and Middle Canal (Division to I-84)

Thursday, June 30, 2022: Boardman Canal (siphon to end)

Treatments will start each day at approximately 6 am and last for 6 hours. 

Argos targets algae and is applied at the rate of 1 ppm for a 6 hour set.  This low rate of application means there are no holding restrictions on the water.  This compares to the Copper Sulfate Crystals which are applied at a 5-6 ppm rate and have lengthy holding time.

Please call the office with any questions at 541-922-3814.


West Extension Irrigation District is committed to water conservation within the District. To further that goal, the Board of Directors approved a rebate program for conservation upgrades to landowners on the Irrigon Pressurized System (IPS). WEID will reimburse 50% of costs for new sprinklers, controllers, valves, etc. up to $200 max for each landowner. Look for your informational postcard in the mail.
