WEID has scheduled the following canal treatments:

• Argos:
  • July 30 = Upper Canal (Phase I inlet to Division)
  • July 31 = Middle Canal (Division to Siphon)
  • August 1 = Boardman Canal (Siphon to End Spill)
• Acrolein: August 7, 2024 (Phase I Inlet to End Spill)

ARGOS - ARGOS is a liquid chelated copper that targets algae.  Treatments will start at approximately 7:00 am each day and take 6 hours at each application site.  It is applied at the rate of 1 ppm for a 6-hour set; this compares to the Copper Sulfate Crystals, which are applied at a rate of 5-6 ppm and have a lengthy holding time.  Treatments are done over 2-3 days due to the lengthy application time.

ACROLEIN (MAGNACIDE H) - Magnacide H (active ingredient Acrolein) targets pond weed and algae.  Treatments will start at approximately 6 am. 

If there are any changes to this schedule, this post will be updated.
