The West Siberian Plain is a large plain that occupies the western portion of Siberia and Russia. Much of the plain is poorly drained and consists of some of the world’s largest swamps and floodplains. In fact, it is one of the world’s largest areas of peatlands, which are characterized by raised bogs. Here some of those marshy areas appear as greyish streaks across the white, snow-covered landscape.

The plain covers an area of more than 975,000 sq.mi. It has been described as the world’s largest unbroken lowland—more than 50 percent is less than 330 feet (100 m) above sea level— and covers an area of about 2.6–2.7 million km² which is about one third of Siberia. It extends from north to south for 2,400 km, from the Arctic Ocean to the foothills of the Altay Mountains, and from west to east for 1,900 km from the Yenisei River to the Ural Mountains.

The principal rivers in the West Siberian Plain are the Ob, Irtysh, and Yenisei. Here, the Ob River is visible in the upper right quadrant. Glacial deposits on the plain extend as far south as the Ob-Irtysh confluence, forming occasional low hills and ridges, but otherwise the plain is exceedingly flat and featureless.

A series of emerald colored lakes dot the landscape of the West Siberian Plain in south-central Russia.

Just over two months ago, during the winter, this whole area was covered with snow and the lakes appeared slate blue or were covered with ice and snow and thus hardly visible (click here for original article). Now, they stand out, a vivid green amidst the brown landscape.

The two large lakes near the center are Lake Kulundinskoye (right) and Lake Chany (left).

Lake Chany is a shallow, freshwater lake that has a fluctuating water level, which can change from season to season and year to year.

A variety of ecosystems that surround the lake include a mixture of wetlands, salt marshes, and a mixture of birch and aspen forests. Lake Chany in particular is critically important for the migratory birds of Siberia.

The Ob River and the Novosibirsk Reservoir, Russia

River, Russia - February 25th, 2009

Snow blankets this part of the West Siberian Plain in south-central Russia.

A series of lakes are visible as black areas in the lower left quadrant, on the southern edge of the plain. The largest and easternmost of these is Lake Kulundinskoye.

North of this lake, bright white due to the snow covering it, is the Novosibirsk (or Novosibirskoye) Reservoir, informally called the Ob Sea.

It is the largest artificial lake in Novosibirsk Oblast and Altai Krai, created by a hydroelectric dam on the Ob River near Novosibirsk. The reservoir is 160 km long and up to 20 km wide.

The Ob River, Russia’s fourth-largest, can be seen in the upper left quadrant above the reservoir.
