Filamentous Algae


Dear Friends of the Lake;

The FLLA has recently received several inquiries regarding the green alga that is in all of Forest Lake. The Comfort Lake Forest Lake Watershed District has provided some information on this alga. There are 2 attachments which really explain what it is.

It is important to note that Forest Lake is not the only lake in the area that has filamentous algae but as many of us have noticed it has never been as bad as this year.

It is also important to note that this algae is not the blue-green which can produce harmful toxins. Usually the blue - green alga occurs later in the summer.

Please read the following information and most importantly read how you as homeowners on the lake can help to reduce nutrients such as phosphorous from entering the lake and contributing to algae growth.


More importantly make sure your neighbors are not contributing to the nutrient load. With only 33% of the lake homeowners belonging to the FLLA it is important to help educate your neighbors. We all use the lake for various activities and we all must help protect it.
If you have any questions please feel free to contact me.

Forest Lake Lake Association Board of Directors
Jerry Grundtner, President
