4. The lake Baikal is in the south-siberian mountains on the border between the
“Oblast Irkuts” on the western and northern bank and the Republic of Burjatian

5. Geographic Dimensions
The lake Baikal, which surface is 31.429 km² big, is with an age of 25 million
years the oldest and with a deepness of 1.637 m the deepest lake of our planet.
The lake, which scale ca 2.125 km amounts, is from south-east to north-east 637
km long (centreline of the lake) and maximal 82 km wide.
The average width is 48 km.
Climate
In the area around the lake dominates a continental climate.
Over the year are ca. 2000 sun hours, in wich the month December is the one
with the poorest solar radiation and the month June with the biggest. The annual
precipitation is 458mm and the average temperature is -1,2 °C.

Flora and Fauna
The Baikal area has a very high density of plants and animals which just life in
this area. This a inimitably flora and fauna.
Over 1.500 animal-and 1000 plant species are endemic. (they live just there and
nowhere else)
There are many spices of fish and other animals which live in the water. A
reason for this diversity of water animals is, the fact that the lake Baikal constant
becomes deeper and deeper. That's why the animals have enough time to change
their way of life and can acclimatize the situation.
But there are much more animals in this area which doesn’t live in the water.
Maybe more than 300 different species of birds live in the Baikal area. Also
many different plants grow in the area around the lake Baikal.
The National Park Lake Baikal is over 2 million hectares big.
In that national park live many different animals e.g. lynxes, bears and harts,
here they can grow up and live under healthy conditions. Many rare kinds of
plants are also in the national park. The vegetations zone around lake Baikal is
called Conifer-Forest.

The Baikal-Rift
The lake Baikal is part of continental Rift zone (Rift break). This Baikal-Rift has
developed in million years and every year it becomes 2 cm deeper.
That rift develops because of splits in the earth's crust, conditioned of collisions
with the southern Indian-Plate wich pushes between the the Amuran-Plate and
the Euroasian-Plate. That's why the Baikal-Rift accrues, on which the lake
Baikal is situated.
The split on that the lake is, is 1.600 km long and soon as 6 km deep.

Islands
In the lake Baikal are 22 bigger islands and on the banks are many isles. The
biggest island is Olchon near the west-bank. That island is is 730 km² big and 72
km long, the mountains are 1.276 high (821 over sea level).
The biggest peninsula is Swjatoj Nos (“holy nose”) at the east-bank.

10. Economy
After the second World war the industrialisation was promoted with much
money. Many factories and mines were build. In special the manufacturing of
cellulose and paper.
The fishing became more import end and many cities around the lake became
bigger. One of the greatest projects and new factories is the Paper- and Cellulose
factory in Baikalsk. 2003 the company got 22,4 million $ for modernization.
But the the hoped success didn’t came and so many people lost their jobs. Also
many hectares of forest were destroyed.
But there are much more different sectors of industry in the Baikal area. Also
very importend for that region is mining. Marble, oil, gas and more is won
around the lake Baikal.
In other ways the shipbuilding is very important too. There are much big
dockyards around the lake. Because many people and company's need ships to
transport things over the lake.
The giant forests in the area are used for timber. But because of deforestation
many areas of forest were destroyed.

11. Infra Structure
Cities and Towns:
Here some Examples for cities and towns near and around lake baikal:
Babuschkin- a small town at the southern bank
Baikalsk- at the southern bank
Irkutsk- a bit away from the south-western bench
Nischneangarsk- city in the north of lake Baikal
Irkutsk
Trafic:
Most of the people live in the cities and towns a bit away from the lake.
Near the benches the region is sparsely populated. There are not so many roads
which come direct to the lake.
In the north and in the south are 2 importend railways. In the north the “Baikal-
Amur-Magistral” and in the south the “Transsiberrian Railway”.
This railways are very importend for the infra structure of that region.
International Airports are for example in Irkutsk or Ulan-Ude.

12. the Transsiberian Railway
When the Baikal lake is frozen over the winter months, it is used as street. That
´s why you can just reach some villages and islands over that “frozen streets” in
winter, which are called “Zimink”.
Nature Conservation
Because of a big destroying of the environment around the lake, the government
began to start projects against pollution and such things.
In many areas reservations and national parks were opened to save rare species
of animals and plants.
There for example the Lena-Naturereservat in the west of the lake or the
Bargusin-Naturereservat in the east.
There are much more national park, e.g. on the island of Olchon.
The lakel is surrounded by a “coast-saving zone”
In 1966 the Baikal-Region became a UNESCO World-Nature- Legacy.

13. Tourism
In some regions around the lake new areas for tourists were build. Many people
enjoy the quietness and the in some region healthy environment. On some
islands you can relax and so on. People how like holidays with adventures will
like the Baikal area, there they can climb and hunt or make interesting walks in
the wild.
A very popular hobby is fishing, because of the many different fish in the lake.
In some parts of the lake is the water temperature in July and August sometimes
around 18 °C. But that s not so often. The most time of the year the temperature
is around 10 °C and in winter it is frozen.
In wintertime ice-skating and races with cars on the frozen lake are popular.
Sometimes people can surf on lake Baikal, because often there are waves which
are more than 3m high.
