The Chisago-Lindstrom Lakes Association’s Aquatic Invasive Species subcommittee has been busy this spring taking care of business! Weed inspectors surveyed North/South Lindstrom and Chisago Lakes for the presence of Curly Leaf and Eurasian Milfoil. Most of the weeds were found in areas within 150 feet of shore or intermixed heavily with native weeds. Matching treatment funding is not available for these areas, so the committee will continue to monitor them. Inspections on Kroon Lake will happen next week.
The inspectors also checked on the Phragmites stands that were sprayed last fall and recorded that 87% of them show significant die-back. The committee will continue their inspections throughout the summer looking for new stands. A fall treatment is being planned to spray any new growth and stands that weren’t mitigated last year.
Today a carp barrier was installed on a small creek that leads from Kroon Lake to the slough area off Schlimmer’s Bay on Chisago Lake. This barrier will keep the carp from spawning in Kroon Lake. These invasive fish start looking for a place to spawn when the water temps are over 62.5 degrees. This is the third year that the barrier has been installed and a big thank-you to the owners for letting us on their properties. CLLA volunteer, Gary Schumacher and LID Supervisor, Jerry Spetzman assisted with the efforts.
