This covering on the surface of lakes and other water bodies is known as eutrophication. The excess level of nutrients that algae depend on results from human activities that cause pollution, such as fertilizer, wastewater, manure, and sewage runoff. Eutrophication can also be a natural occurrence from moderate accumulation of organic matter, silt, nutrients, and sediments gradually from the watershed.
