Phragmites Treatment

The Chisago Lakes Phragmites Eradication Project reached a milestone last week, with the commencement of Non-native Phragmites treatment on North and South Center Lakes.

Lakes Management Inc. is spraying Imazapyr, which is a non-selective herbicide used to control emergent aquatic weeds like Phragmites australis . They are following the recommended protocol set up by the Minnesota Aquatic Invasive Species Research Center (MAISRC) and the Minnesota Department of Natural Resources (DNR).

Treatment of Chisago Lake, North and South Lindstrom Lake stands happened today. Lakes Management and a team of volunteers will go back out in two weeks to assess the effectiveness of the treatment. If needed the Non-native Phragmites stands will be retreated. This winter lake association volunteers will cut or burn the dead stands.

We anticipate this project to be ongoing until we successfully eradicate this menace weed from our shorelines. Please continue to inspect your property and report any phragmites present using our contact form. We will be happy to come out and inspect your shoreline!

If you couldn’t attend the Eradicating Phragmites Meeting, Cable Television Public Access Channel 10, Cable Commissioner, Jack Doepke filmed the meeting. You can watch the video at:

Letters were sent out to landowners that have invasive Phragmites with an option to opt-out of the free treatment. Written notice must be received by August 15th. See the Phragmites Eradication Project tab on our website for the opt-out form.

Please contact your local lake association if you have any questions.

Biological Control for Purple Loosestrife

Members of the CLLA Aquatic Invasive Species committee attended a MN DNR Workshop on how to collect beetles (black-margined loosestrife beetle and golden loosestrife beetle) that only eat invasive Purple Loosestrife. Over the last four years the group has manually pulled these plants from our lake shores.

This workshop gave us the tools and one-year permit to harvest and transport beetles to a local site. Hopefully the beetles we collected and released will like their new location. We want to establish a local colony of beetles that will biologically take care of this invasive plant in our area.

Here are some pictures from the day …

Water Action Day 2019

Representatives from Chisago-Lindstrom Lakes Association and Green Lake Association met with  Representative Ann Neu and Senator Mark Koran at Water Action Day at the State Capitol today. Both our legislators were receptive to our concerns regarding Aquatic Invasive Species treatment funding and the economic impact of water quality on our local economy.


Hiding in Plain Sight – Invasive Phragmites

Phragmitres Meeting
Invasive Phragmites Meeting – Thursday, October 25, 2018

Great turnout to hear MAISRC Researcher, Julia Bohnen talk about the non-native Invasive Phragmites invasion in the Chisago Lakes Watershed.  Over 86 sites have been identified in our area and good news is the sites are small enough to be effectively treated. Various stakeholders will be putting together a management plan to be implemented next fall.

Ms. Bohnen described how to identify Invasive Phragmites and provided the following handout:  mnphrag_identification_guide_v6-18

The best time to treat Invasive Phragmites is late August – September using the following treatment plan:  invasive_phragmites_management_recommendations

Phragmites – Hiding in Plain Sight

The Chisago Lakes Coalition of Lake Associations (CLCLA) is concerned with the explosion of non-native Phragmites (Phragmites australis) along our area lakes shorelines. We will be hosting a meeting of stakeholders from local governmental entities, Minnesota Aquatic Invasive Species Research Center and area Lake Associations to develop an effective management plan to deal with this invasion.

The meeting will be held on Thursday, October 25th from 3:00 to 4:30 at the Chisago Lake Township Hall at 12400 316th Street, Lindstrom, MN. MAISRC Phragmites Photo

Since multiple years of treatment will be needed to achieve effective control of non-native Phragmites, we hope to slow the growth before it overtakes our shorelines and roadside ditches. But we can’t do it without your help. Please join us to stop the spread!


How to inspect for Zebra Mussels

Benjamin Franklin was quoted as saying, “An ounce of prevention is worth a pound of cure.” An apt saying when it comes to dealing with Zebra Mussels. Best practice is to CLEAN your boat of any aquatic weeds before leaving the launch area, DRAIN water-related equipment such as your boat, bait-bucket or livewells of any water and DISPOSE of unwanted bait in the trash. If you want to keep your bait please replace the lake water with  tap or bottled water.

Another way to be proactive is to be on the look out for Zebra Mussels on your dock posts as you pull your equipment out of the water for the season. The Chisago-Lindstrom Lakes Association has seven monitoring samplers on all four of our lakes: North Lindstrom, South Lindstrom, Chisago Lake and Kroon Lake.

If you don’t have access to a Zebra Mussel plant sampler and would like to assist our efforts – tie a rope around a small cinderblock and place it under your dock.  The following link shows How to inspect a Zebra Mussel plant sampler

The Chisago Lake Lakes Improvement District has developed a rapid response plan in the event of Zebra Mussel detection. The earlier these Aquatic Invasive Species are detected the quicker we can start treatment.
