Eutrophication: A Silent Killer of Lakes
Eutrophication is the nutrient enrichment of waters that stimulates an array of symptomatic changes that can include increased phytoplankton and rooted aquatic plant (macrophyte) production, fisheries and water quality deterioration, and other undesirable changes that interfere with water uses. For a layman eutrophication is simply a nutrient enrichment or fertility of lake. The impacts of eutrophication are more severe than recognized. Vonlanthen and his co-workers (Nature, 2012) provided an evidence that eutrophication can lead to extinction or ‘speciation reversal’ and ‘demographic reversal’ in Whitefish across European Lakes.

Eutrophication is most often the result of an elevated supply of nutrients, particularly nitrogen and phosphorus, to surface waters that results in enhanced production of primary producers, particularly phytoplankton and aquatic plants.

Apple River Harvester Removes 1200 tons of Aquatic Plants - The strategy of the Apple River Protection and Rehabilitation District was to remove as much of the curly leaf pondweed as possible early, then systematically move up and down the Flowage keeping the main navigation channel clear plus providing access channels to the resident along the shoreline whenever practical.
