Many lakes throughout the world are undergoing eutrophication (accelerated ageing) due to man’s activities. These lakes often become an environmental nuisance, because of impaired water quality, fermentation processes during anoxic periods, prolific weed growth, excessive algal blooms, and deteriorating fisheries. International concern has stimulated research on the nature and causes of the lake-aging process including the development of various control techniques. Lake restoration has become a subject of considerable interest (Bjork, 1974a, Dunst et al, 1974) and several measures have been proposed to restore lakes. But lakes are complicated ecosystems and the ability to predict the response of a lake to various measures is as yet limited. Moreover, each lake has its own “unique personality” which means that it is impossible to establish a standardised treatment. A co-operative effort with public administrators, politicians and technicians is necessary when planning restoration of lakes.
