West Extension Irrigation District will be applying the aquatic herbicide “Argos” (liquid chelated copper) in its main canal in 3 treatments:

Wednesday, August 26, 2020      Upper Canal (Phase 1 Inlet to Division)

Thursday, August 27, 2020          Middle Canal (Division to I-84)

Friday, August 28, 2020               Boardman Canal (siphon to end)

Treatments will start at approximately 7 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.
