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.
