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.

IPS – All pumps are up and running.

DIVISION STREET – The pump stayed on overnight last night, and went off this morning on its regular schedule. Will be turned back on in the morning.

May 10, 2022 – 1:30 p.m.

IPS – The 4th Street Booster Station has electrical problems. It will remain off until the electrician can get it fixed. All other booster stations are on.

DIVISION STREET – Will be left on overnight tonight, then turned off Wednesday morning (its normal schedule). It will come back on Thursday morning and we are hopeful there will be enough use to keep it on, back on schedule.

May 9, 2022 – 9:45 am.

IPS – River pumps were turned on at 7:45 this morning. After the system has filled, crews will begin turning on the booster stations. Keeping the booster stations on will depend entirely on how much usage is on each station. NIGHT IRRIGATION IS IMPORTANT to keep the boosters on overnight. We really need your help to keep the system up

DIVISION STREET – The pump was turned on Saturday during the day, and we will do the same today. It will be turned off by the ditchrider on her way home. As will all of the pump stations, there needs to be enough use to keep it on. If your systems are set up for night irrigation, please call the office and let us know. We really want to be able to keep it on all night on its regular schedule.
