Actively Taking Part in Projects that Promote the Conservation & Successful Future of Lake Osakis
Throughout the year the Osakis Lake Association, with the endorsement and support of various agencies, groups, and volunteers, has accomplished and been an active partner on many projects. Donating our time, talents, and often nominal resources, the OLA has assisted with the following projects, and will continue to be involved whenever possible.
Curlyleaf Pondweed (CLP) is an Aquatic Invasive Species (AIS) that has supported algae blooms and
contributes to shoreline plant residue on Lake Osakis. CLP was identified in MN around 1930 and likely
introduced to Lake Osakis shortly after. CLP was reduced substantially with a state pilot project in 2007-
2009, on parts of the lake. Due to limited funding continued maintenance was not implemented resulting
in the CLP population spreading substantially. The project purpose is to reduce the algae and shoreline
plant residues resulting from the CLP.
The Petition of Todd and Douglas County Commissioners and City of Osakis asking them to create a Lake
Improvement District (LID) is enclosed. This would result in lake property assessments by the county. The
county would be the taxing authority. Osakis Lake Association Fund raisers, Donations and Grants would
contribute to decrease the 848-Lake Property owner’s cost. A public meeting will be part of this process
which will be announced later. The LID will be vital for us to fund the much-needed improvements to Lake
Osakis making it more enjoyable for years to come.

Curlyleaf Pondweed /Planning 2022 6/24/2021
Curlyleaf Pondweed (CLP) is an Aquatic Invasive Species (AIS) that has supported algae blooms and shoreline plant residue on Lake Osakis. The entire Lake Osakis has been surveyed to determine the locations of CLP. This survey was completed by Blue Water Science (see attached map). There are 367 acres identified to potentially obtain a DNR Permit in 2022 to apply. Aquathol K is the herbicide of choice for CLP management and pricing can be variable. A spring survey will also be required prior to DNR permitting. There are Aquatic Invasive Species (AIS) grants available from DNR and County AIS programs, the amounts available varies based on county demand.
The 2022 cost is estimated to be $547 per acre. If there is enough funding to spray all 367 acres the total cost will come to $200,749, before the grant money is applied (unknown amount at this time). It is recommended the areas be treated 3-5 consecutive years based on survey results each spring.
The Local County Commissioners and City of Osakis have been asked to consider creating a Lake Improvement District (LID). This would result in property assessments. Osakis Lake Association Fund raisers and Grants would contribute to decrease the 883-property owner’s cost. A public meeting is being planned for the near future to discuss the process for LID creation on Lake Osakis. The LID will be vital for us to fund the much-needed improvements to Lake Osakis making it more enjoyable for years to come.
