14, 15, 18, 22 The water purification systems of the towns of Salcininkai, Druskininkai, Svencioneliai and Kaunas have only the mechanical stage of purification. Biological cleaning is absent. The untreated waste waters are drained directly to the rivers in the amounts mentioned accordingly: 0,2 million m3, 1,2 million m3, 0,1 million m3 21,4 million m3.

24, 25 - The HPP of the Valtunai on the river of Siesartis and the HPP of Kavarskas on the river of Sventoji.
The dams have broken the natural water mode of the rivers. Inspite of the existing fish laders the majority of the fish species are not able to overcome them.

4. The National Park “Narochansky”
The National Park “Narochansky” was established in 1999. The park's total area is 117000 hectares of which 17 % are covered by wetlands including 36 lakes and numerous small rivers which provide good habitat for brook trout and grayling. Majority of the small rivers in the park are part of the river Vilia basin.

9. The river Tartak is a spawning ground for the Atlantic salmon species
There are more then ten brown trout (Salmo trutta) spawning nests in the river recorded recently. According to some records the Baltic salmon species (Salmo salar) have also been found in the Tartak river.

13. River Vilia
The river Vilia downstream the Vileyskaya dam is a natural habitat for brook trout, grayling and a migration route for Atlantic salmon species.

6. Vileyskaya dam.
Vileysky reservoir was built to provide water to Minsk, the capital city of Belarus. Because the dam did not have any fish ladders installed it cut the migrating salmon species from their spawning grounds upstream. Drop in water discharges from Vileysky reservoir during dry seasons leading to a significant reduction in the river flow downstream. It makes an adverse impact on the river ecology downstream and causes water shortages in the Vilnius area.

7. Agricultural pollution.
There is a large livestock unit near Belaya village with 2000 cows (used to be 4000) currently kept. All the unit farm yard manure storage ponds are uncovered and almost constantly overfilled with slurry which drains down the channel connected to the river Vilia.

8, 5. Dams on rivers Stracha and Oshmyanka do not have any fish passages.
The Stracha and Oshmyanka rivers lost their significance as a migration route for salmon after the dams were built near the Olkhovka (8) and Snigyany (5) villages.
