**UPDATE** CANAL TREATMENT SCHEDULED

UPDATE – DATE CHANGE FOR MIDDLE AND BOARDMAN

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

  1. Upper Canal (Phase 1 Inlet to Division) – Wednesday July 17
  2. Middle Canal (Division to I-84) – FRIDAY JULY 19
  3. Boardman Canal (Siphon to end) – THURSDAY JULY 18

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.

Please call the office if you have any questions at 541-922-3814.
