Most of the lakes are a focus of public interest and are subject of different types of utilisation. The production of energy and drinking water, regulation of the water level, fish farming, local recreation, bathing, fishing and different water sports such as sailing, surfing or water skiing as only some examples. At the same time lakes are also ecosystems reacting differently on the utilisation and other influences from outside.
Due to these influences many of the lakes have changed and now show the typical problems of eutrophication, such as an extreme increase of algae, lack of oxygen, silting and a depletion of aquatic habitats.
It is necessary to gain knowledge about its evolution/origin, its catchment area, its morphology, its temperature regulation and its overall balance of matter in order to sustainably guarantee the utilisation and at the same time the function of a lake as ecosystem. The science dealing with these correlations of inland water ecosystems is the limnology. The planning and implementation of remediation and restoration measures has to be based on limnological investigations and evaluations.
