The Chisago-Lindstrom Lakes Association has received permission from the MN DNR to treat for the Aquatic Invasive Species, Euasian Water Milfoil in the lakes of our Association. Treatment will occur on Wednesday, June 22, 2022, weather permitting. If treatment is postponed, we will post a notice with the rescheduled date.
The CLLA has levereaged our member dues with Chisago Lakes Lake Improvement District funds and MN DNR Grants to pay for the treatment of the areas outside of the 150 foot mark. In some instances, property owners on North Lindstrom and Kroon Lake have authorized and will pay for treatment within 150 feet of shore. Weed surveys (delineations) were conducted earlier in the month and treatment plans were approved by the MN DNR.
Lakes Management, a DNR certified/trained application company will be conducting the weed spraying. They will either be using the systemic herbicide chemical, 2-4 D or Triclopyr. Both of these chemicals are safe to use around the water ecosytem. Out of extreame caution, please refrain from swimming or letting your pets in the areas that have been treated for 24 hours.
The maps linked below indicate the areas to be treated.

Is this treatment for blue algae?
Just moved to South Lindstrom so not familiar with harmful lake algae.
Thanks
No, this treatment is to reduce the amount of Eurasian Watermilfoil weeds in our lakes. This Aquatic Invasive Species forms dense mats on the water reducing the recreational use of the lake.
Blue Green Algae (a bacteria) is formed from excess nutrients the water usually due to fertilizer or urban runoff.
