Hybrid Milfoil in Michigan Lake Raises Control Challenges

Pentwater Lake Improvement Board President Joe Primozich recently issued an update on changes going on in overall health of Pentwater Lake in Michigan.

Primozich said according to Progressive AE, the Grand Rapids company that monitors the lake vegetation, the aquatic invasive water milfoil has now changed to the hybrid form.

“This means that it has a greater tolerance to herbicides and will require a more costly treatment than dealing with the native northern milfoil or the exotic Eurasian milfoil of the past 16 years,” Primozich said. “This appears to be a more aggressive growth pattern.”

Pentwater Lake shoreline owners (riparians) have petitioned the Pentwater Lake Improvement Board to substitute suction harvesting for the chemical treatment of floating vegetation mats for 2017. A presentation on mechanical harvesting will be held on December 14th.

Lake Hallie Lake Association is making some headway in the war they’ve been waging against the hybrid watermilfoil weed.

First discovered in Lake Hallie in 2005, watermilfoil is an invasive aquatic plant that has an aggressive tendency to form a thick mat-like layer as it floats on the water. If left unchecked, this plant can cover huge areas of water, blocking sunlight from reaching more desirable plants and making boat traffic difficult.

Using a weed harvesting machine, the Lake Association harvests from May to September, multiple times per week. Over the course of the season, from 200-300 tons of the plant are removed from the lake.
