The Ignalina nuclear power plant is in the immediate vicinity . |
Lake Drūkšiai ( Belarusian Дрысвяты Dryswjaty ) is located on the border between Lithuania and Belarus . It is the largest lake in Lithuania and is located near the town of Visaginas in the Utena district . The lake was used as a cooling water reservoir by the nearby Ignalina nuclear power plant .
General
The lake has an area of 49 km² and includes seven islands . The nearby nuclear power plant is connected to the lake via two canals. In the lake and near the coast there are over 500 different species of higher vascular plants , as well as 95 species of aquatic and semi- aquatic plants. Many of these plants are rare or protected. In addition, the lake is a habitat for many different types of fish and crustaceans that are very rare in the Baltic Sea region. Over 250 plankton species and 25 different fish species are housed in the lake. There are also some protected mammal species in the area around the lake.
The lake was threatened by the discharge of sewage from the Ignalina nuclear power plant, which is polluting the lake. In addition, the warm cooling water introduced led to increasing eutrophication of the lake. However, after the Ignalina nuclear power plant was shut down in 2009, the entire ecosystem of the lake may change again. The successor nuclear power plant Visaginas will either get the cooling water from the lake like the nuclear power plant Ignalina or get a cooling tower . No decision has yet been made. All options were declared feasible. The new nuclear power plant, like the Ignalina nuclear power plant, will only use 20% of the lake's surface water for cooling and heat it to a maximum of 26 ° C.
Data on the flora , fauna and hydrology of the lake and its surroundings have been recorded since the beginning of the 20th century . Six research institutes from Lithuania as well as other scientific institutions from several other countries are examining some data from the lake area. This research led to publications and monographs .
