Abstract The eutrophication process is described giving lake characteristics and classification. Causes of eutrophication are discussed, including factors influencing aquatic plant production, types of aquatic plant nutrients, together with concentration and sources of nitrogen and phosphorus, which include domestic and industrial waste waters, urban and agricultural drainage and natural sources; the role of lake sediments, atmospheric sources, ground waters, marshes, and nitrogen fixing bacteria and their interaction with nitrogen and phosphorus sources are outlined. The parameters to be considered in measurement of eutrophication are evaluated. Effect of eutrophication on domestic, industrial, and recreational uses of water are outlined. A summary of methods used in reducing and controlling effects and rate of eutrophication includes nutrient removal from waste waters, waste water diversion, dredging, flushing, chemical and biological control of nuisance plant growth, harvesting, lake aeration, control of agricultural sources of nutrients and control of urban drainage, hypolimnetic withdrawal, water level management, and immobilization of nutrients.
