CANAL TREATMENT SCHEDULED

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

Wednesday, June 23, 2021 (morning)                 Upper Canal (Phase 1 Inlet east of Power Line Road to Division)

Wednesday, June 23, 2021 (afternoon)               Middle Canal (Division to I-84)

Thursday, June 24, 2021  (morning)                    Boardman Canal (siphon to end)

Treatments will start 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 is applied at a 5-6 ppm rate and have lengthy holding time.
