2018 AIS Inspections and Background Data

Curly-leaf (sometimes called curly-leaf pondweed) is an Aquatic Invasive Species (AIS) that was introduced into our area lakes around 1910 and can probably not be eradicated. It grows in the winter-time; and when there is not a lot of snow, you get more curly-leaf. Since about 2014 our past years’ winter conditions have been perfect for the growth of curly-leaf, unfortunately. The best time for removal of curly-leaf is within weeks of when the ice melts. Trying to harvest the weeds in the spring and summer merely spreads the seeds around.
There are certain areas of Farm Island Lake that have curly-leaf. The FILIA Board Members ask that people with curly-leaf work together to determine any action taken.
The MN DNR has a section on their website devoted to Aquatic Invasive Species - Programs, Reports, and Partners. Click here to learn more. Contact information can be found there, along with a website page specific to curly-leaf.
