Notice of Upcoming Euasian WaterMilfoil Treatment

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.

Euasian Watermilfoil

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.

2021 Phragmites Treatment Successful

On Thursday, September 23, 2021, forty-two stands of invasive Phragmites were treated with the DNR approved herbicide, glyphosate or imazapyr. In the past three years, CLLA has found and treated over 60 stands of the invasive Phragmites on North Lindstrom, South Lindstrom and Chisago Lake. No invasive Phragmites stands have been found on Kroon Lake.


The Chisago Lakes Area Foundation provided CLLA with a grant in 2017 that enabled us to inform the local community of the invasive Phragmites problem. Once invasive Phragmites gets established, it quickly pushes out native plants and takes over shorelines.

CLLA collaborated with the University of Minnesota MAISRC (Minnesota Aquatic Invasive Species Research Center) to develop a management plan to identify and treat the invasive Phragmites. Also, our local lake associations have worked closely with MAISRC and the MN DNR to define the state-wide protocol for the eradication of Phragmites.


Funding for the actual treatments was obtained from the Chisago Lake Lakes Improvement District and our lake association (through member dues). The invasive Phragmites stands were treated by Lakes Management, Inc.


We expect the eradication of invasive Phragmites will be an ongoing project as more infested stands are likely to be found and any treated stands will have to be revisited each year to ensure that regrowth does not occur. If you would like to be part of the AIS weed inspectors, please contact us at chisago.lindstrom.lake.assc@gmail.com.

Eusasian Milfoil found In Kroon Lake

On October 7, 2021 Chris Jurek, the MN DNR aquatic invasive species specialist for our area confirmed the presence of Eurasian Milfoil in Kroon Lake. The Chisago Lakes Lake Improvement District’s AIS Specialist, Camden Droppo mapped out the different locations of the invasive milfoil using a sonar device. The coordinates will be used to draw up a recommended treatment area for next spring.

The Chisago-Lindstrom Lakes Association will apply for the permit to treat this invasive and request grant funding from the Chisago Lakes LID for any Eurasian Milfoil present 150 feet away from the shoreline. Please note that the LID will not approve grant funding for any invasive weed treatments within 150 feet of the shoreline.

Therefore, the CLLA will help facilitate homeowners on Kroon Lake that are interested in treating inside of the 150 feet from the shoreline. If you would like to be part of the group, please contact the CLLA via the contact form on this website or emailing chisago.lindstrom.lakes.assoc@gmail.com.

2021 Invasive Phragmites Survey Completed

The Chisago-Lindstrom Lakes Association (CLLA) Aquatic Invasive Species Subcommittee has finished surveying the lakes in our association and found an additional five stands of the Invasive Phragmites. All of the stands that were treated last year were revisited and notations were made as to which need additional treatment this year. There are currently 60 stands in various stages of treatment. Five new sites, 37 previously treated sites that need retreatment and 18 eradicated stands.

This treatment will occur in mid September and the DNR approved herbicides glyphosate or imazapyr, alone or in combination will be used. This treatment is at no cost to the lakeshore property owner. Funds for treatment come from our lake association (member dues) and grant funding from the Chisago Lakes Lake Improvement District.

Notice in the Chisago County Press dated August 26, 2021

If you have invasive Phragmites on your shoreline and would like to opt out of this treatment, please fill out the opt-out form located on our Phragmites Eradication Project webpage located at https://clla-lakes.com/phragmites-eradication-project/ and mail back to us at the address listed on the form.
