  3. 3. The Lena River The River Lena is one of the planet’s greatest rivers. It carries its waters as far as 4,400 km from its source in the mountains near Lake Baikal to the Arctic Ocean. In the middle of the stream the distance between its banks reaches 15 km; it is as wide as 20 – 25 km in the downstream. And the width of the river mouth is mentioned in Guinness book. The area of the Lena river basin is calculated at 2,490,000 square kilometres (961,394 sq mi), and permafrost is typical of the whole territory.
  4. 4. The Lena River The river gets much water supply from rain and snow. For seven months the river is frozen in ice more than 1 m thick. Freeze up starts in late October, ice breaking and ice-floating starts in the second half of May. The river is home to many kinds of animal and plant life, 37 species of fishes are found in its waters, silver salmon (taimen), lenok, grayling, bass, whitefish, pike are among them.
  5. 5. The banks of the river are covered with thick forest – taiga: there you willsee huge pines with golden-red trunks, thick cedars, dark spruce, fir-treesand tall larches. Vast area of the River Lena basin is homeland for manySiberian people: yakuts, evens, evenks who have close ties with thenature.
  6. 6. The Lena River Some of the Lena tributaries, such as Vitim, Olekma, Viluy, Aldan are greater than many big rivers of Europe. The river doesn’t have any weirs, or dams, or hydro power stations. The river flows along its natural riverbed like millions years ago. You still can drink its water right from the river. Yakutia is the land of amazing picturesque, severe and beautiful nature that inspires artists and poets. A traveler will meet kind, interesting and hospitable people here; and charms of local nature will make him visit this land again.
  7. 7. Besides the Lena River there are lots of other big and small rivers and lakes on the territory of our region and republic. Many of them are of vital importance for he population. The students of different schools monitored water quality in the Lena River and other small rivers and lakes. When we started the project there were 10 schools participating in it. Later a few schools from other regions of the republic joined us in the project.

  20. 20. The Lena Cantata by Peter Bernov, the local poet Ах ты, Лена, красавица Лена, Ты как песня, мне в душу вошла, И протоки с черемухой белой, И разливов твоих зеркала. Много рек, и больших, и не очень, Зазывали меня на причал. Но признаюсь тебе, между прочим- Красивее тебя не встречал. Многих ты красотой покорила, Разноцветьем прибрежных полян,Словно мать, своей грудью вскормила Не одно поколенье землян. Много песен, душевных и славных, В твою честь я исполнить готов. Ты проходишь артерией главной Через сердце моих земляков. Свои чувства к тебе и признанье, свою радость и легкую грусть Мне не выразить даже словами – Просто в пояс тебе поклонюсь.
