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.

Aquatic Weed Harvesting Update - The lake weed harvester began operation for the season on May 4th. This year it has been operating five days a week, with some of those days having extended hours. To date, 382 cubic yards of aquatic plants have been removed from the lake...which is 64 truckloads of lake weeds disposed of just this year! During the same period last year, 94 cubic yards of aquatic plants were removed from the lake.
