We found in them beauty, mystery, and tranquillity. Lakes continue to inspire our daily lives, while at the same time providing transportation, an abundant food supply, and water for drinking and bathing. By serving as a critical link in the ecosystem, lakes also are important sanctuaries for our fish and wildlife. Dredging may be appropriate for lakes whose sediments are high in nutrients.
Chemical precipitation is possible.
Dilution or flushing is possible if large quantities of low nutrient water are available. Harvesting of both algae and macrophytes can remove nutrients. Lake sediments can be sealed to prevent nutrient release. Artificial aeration techniques can be used to improve water quality, and provide suitable cold water habitat during periods of restricted circulation. The different pathways of phosphorus and nitrogen in lake metabolism make phosphorus the obvious choice for eutrophication control.
