Abstract
Problems relating to the disappearance and eutrophication of lakes as a result of human activity are presented. A study area was selected located in an agricultural/forest region where human influence on lakes used to be minimal.
In the past 25 years a number of lakes have completely disappeared and others have become rapidly enriched. Human interference has included: the pulling down of water mills, drainage and river canalisation, construction of holiday resorts, development of intensive farming, increased mineral fertilization, and the extension of roads and road traffic.
