Where is deepest lake in the world

Russia's Lake Baikal is the deepest lake in the world by far. Lake Baikal is about 25 million years old, making the lake the oldest in the world, too. The Lake's incredible age has allowed a rich, unique assemblage of life to flourish, including the Baikal seal, the Baikal oil fish, and the Baikal omul fish. The lake's diversity has led some to refer to it as the "Galapagos of Russia".

Map from the CIA Factbook. Crater Lake: Panorama view of Crater Lake showing the steep crater wall that surrounds the lake and Wizard Island, a small volcano within the crater. Its deepest measured depth is 1, feet meters. It is the ninth-deepest lake in the world. It is an amazing lake because no rivers flow into it or out of it.

The water level in the lake is a balance between rainfall, groundwater flow and evaporation. The lake is a volcanic crater that formed about years ago in the aftermath of one of the largest volcanic eruptions in recent geologic history. The explosive eruption ejected about cubic kilometers of material, then the volcano collapsed into the empty magma chamber below to form a deep basin known as a caldera.

The deepest areas are in the northeast portion of the lake. Enlarge map. It is worth noting that estimated lake depths are just that - estimates. In fact, they are estimates of depths that change over time! Searching online, a person may find several different depths listed for the same lake. Why is this? Crater Lake, for example, does not have any streams or rivers flowing into or out of the lake. The water level is relatively constant because, remarkably, the amount of water coming into the lake via rainfall and snowfall generally equals the amount of water going out of the lake via evaporation and seepage.

Since the depth of Crater Lake is directly influenced by the climate, it is easy to imagine how the water level would drop in a year of drought, or how the lake would become deeper in a year of record precipitation. These ideas can be applied to lakes fed and drained by rivers as well.

Local legend holds that Jesus visited Lake Baikal, according to Smithsonian magazine. Russia expanded its territory to include Lake Baikal during the 17th-century Russian conquest of Siberia. The age, isolation and deep oxygenated water of Lake Baikal have resulted in one of the world's richest freshwater ecosystems.

About 80 percent of the more than 3, species found at Lake Baikal are endemic, meaning they are found nowhere else on Earth. Probably the most famous of these species is the nerpa, the world's only exclusively freshwater seal.

Scientists are unsure how the nerpa came to Lake Baikal and evolved, but they suspect the seals might have swum down a prehistoric river from the Arctic, according to LakeBaikal. Other endemic species include the oily, scaleless golomyanka fish and the omul, a white fish that is one of Lake Baikal's most famous dishes.

Other land-based species around Lake Baikal include bears, reindeer, elk, wild boar, Siberian roe deer, polecats, ermine, sable and wolves. Aquatic invertebrate species include more than species of flat worms, more than species of anthropods insects, arachnids and crustaceans and more than species of mollusks.

These invertebrates all help purify the water. There are dozens of tree species, including cedar, fir and spruce, growing in the Lake Baikal area. Some of the trees are up to years old. The Angara pine tree is native to the area, according to Baikal World Web. As Russia and Mongolia have become increasingly industrialized and tourism has increased, Lake Baikal has faced more and more threats to its environment.

Additionally, climate change is threatening its ecosystem. Water temperatures and ice cover have already changed, according to BioScience. Castner described several of the dangers facing Lake Baikal. The biggest threat is probably the "huge problem with algae on the lake and government failure to develop an adequate response to it," she said.

Massive green algae blooms plague bodies of water like the Great Lakes, but for a long time Russian scientists assumed that Lake Baikal was too big to be affected by them. But since at least , Spirogyra algae blooms have appeared on the bottom of the lake, according to National Geographic.

The algae blooms are found in shallow water and wash up on shore, where they emit a horrible stench. The algae are toxic to other species. The algae have damaged water snails, sponges, fish and crustaceans — which pass the toxins along to people, according to the New York Times. The concentration of algae in shallow water and the fact that algae blooms have historically appeared in areas with untreated sewage suggest that untreated sewage is a significant contributing factor to the problem.

She added, "There's a huge increase in tourism on shores all around the lake and there's not a real understanding of how that's affecting the lake. But at least one effort to healthily manage tourists at Lake Baikal is succeeding: the Lake Baikal Trail, which will surround the entire lake, is being built slowly but surely.

Mongolia is actively planning to build the dams in order to obtain energy.
