Aquatic Plant Life

Since 2016, the Lake Manitou Association Board of Directors has contracted with Clarke Aquatic Systems to monitor the plant life in our lake. Clarke performed a series of samplings in 2016 and 2017 to monitor our aquatic growth.  So far they have seen a healthy comeback of native plantlife following the last few years of hydrilla treatment. In 2017, treatment for hydrilla was completed. The DNR has been on the lake to evaluate any signs of hydrilla and thankfully, it has not returned.


Clarke Aquatic Goals for Lake Manitou:

To enhance and preserve the natural balance of the lake in the most environmentally-friendly manner so you and your community can enjoy the recreational and aesthetic value of your lake to the fullest.

"We want to encourage native vegetation to reestablish itself back in the lake so that exotic invasive species have less of a chance to take over the lake as it has in the past. Water quality, clarity and fish habitat will all improve once more native species are introduced. This will happen naturally with time and our job is to monitor what species are coming back, the density and the locations.  If exotic invasive species are found, we will target those plants only to ensure we do not disturb the natural habitat."

-Joe Haufle, Aquatic Specialist, Midwest, Clarke Aquatic

A series of three separate samplings were performed in 2016 to measure the species and growth rate of plant life in Lake Manitou.  The results were very favorable.  A summary of Clarke's findings is below.  The Plant Life Sampling (Aquatic Vegetation Summary Sheet) shows the names of weeds found and densities.  The Plant Life Map is a visual of these findings.  You can see the progression of growth throughout Summer 2016.  2017 data should be available from Clarke soon.
