2025 Aquatic Invasive Species Control

The Commission will be treating Lower Twin Lake in Robbinsdale, Eagle and Pike Lakes in Maple Grove, and Meadow Lake in New Hope for curly-leaf pondweed sometime in Spring 2025, exact dates TBD. The proposed treatment maps are shown in the figures on this page. Check the Commission's Facebook page for notification of treatment once scheduled.

The Minnesota Department of Natural Resources has granted to the Commission a waiver of the requirement to obtain the signatures of approval of owners of lake-shore property.  Instead, the Commission is notifying property owners of the treatment by posting public notice. The treatment is for curly-leaf pondweed which is a non-native plant that grows in the spring and early summer.
 
Key information:
1) Date range of treatment: April-May 2025
2) Target Species: curly-leaf pondweed (Potamogeton crispus), an aquatic invasive species. 
3) Chemical treatment will be applied by an MnDNR certified applicator. Diquat will be applied to Lower Twin Lake (Robbinsdale), Eagle (Maple Grove), and Pike (Plymouth and Maple Grove); and flumioxizin will be applied to Meadow Lake (New Hope).
 
Please contact the Commission with any concerns or questions.

Note that the Meadow Lake treatment map is dated 2023. The commission is proposing to use the same treatment areas in 2025.
