Yenisei is the biggest river system that flows to the Arctic Ocean. It is one of the three extraordinary Siberian waterways (the other two being the Ob and the Lena). Rising in Mongolia, it follows a northerly course to the Yenisei Gulf in the Kara Sea, draining a large part of Siberia’s mainland.

Key Facts & Information
- Yenisei is the fifth-longest river on the planet. It is somewhat shorter than the Mississippi River, yet it has 1.5 times the outflow. It originates in Mongolia and follows a northern course to the Kara Sea.
- From the split, the Yenisey River runs for 2,167 miles (3,487 km), mainly along the outskirt among eastern and western Siberia, before purging into the frosty Kara Sea.
- The longest river following the Yenisei-Angara-Selenga-Ider is around 5539 km long. Its watershed, which incorporates the world’s biggest (by volume) lake, Lake Baikal, holds more water than some other stream framework.
- With the incorporation of the Selenga, Yenisey is 3,442 miles (5,539 km) long and depletes an area that, at 996,000 square miles (2,580,000 square km), is the seventh biggest on the planet.
- A portion of the Yenisei water originates from snow, 33% from rainwater, and the rest comes from groundwater.
- For the greater part of the system, the eastern Siberian hydrologic regime flows: violent spring floods are followed initially by a rapid fall of levels, then by a slower fall, with summer and autumn rain floods that follow. In winter the runoff is reduced a bit, but the levels remain high as ice blockages are formed.
- It conveys about 10.5 million tons of alluvium into the Kara Sea each year, notwithstanding almost 30 million tons of broken up mineral substances.
- In midsummer, the water temperature differs from 57 °F (14 °C) to 66 °F (19 °C), yet freezing starts on the lower Yenisei in October and affects the whole waterway by mid-November with ice blocks and submerged ice.
- Thawing occurs towards the end of April on the upper reaches, in May on the middle, and from May to the middle of June on the lower.
- The water at the center of Yenisey is profoundly cloudy in spring and summer, and stands out from the clear water of the Angara.
- In summer, the two rivers flow in a similar path without joining for 9 miles (14 km) or so.
- The Yenisei basin has a subarctic atmosphere in its northern part and especially continental conditions in the center and southern parts.
- The cold season is from late September to mid-June in the north and from mid-October to late April in the south. Summer is cool in the northern area, with normal temperatures of 46 to 54 °F (8 to 12 °C) in July, when ice may happen. Summer, however is warm in the south, with July midpoints somewhere in the range of 64 and 68 °F (18 and 20 °C).
- The normal temperature for January in the north ranges from −25 to −18 °F (−32 to −28 °C) and in the south warms to about −4 °F (−20 °C).
- Yearly precipitation is around 16 to 20 inches (400 to 500 mm) in the north; 20 to more than 30 inches (500 to more than 750 mm) in the central part, and up to 47 inches (1,190 mm) in the mountainous south.
- The closed depressions in the upper basin receive less than 8 to 12 inches (200 to 300 mm) annually.
- The vast majority of the downpour (80 to 90 percent) falls in the hotter months, mostly in pre-fall and early harvest time.
- Snow spread is light in the majority of the basin, averaging 16 inches (40 cm) in the south, 24 inches (60 cm) in the north, and 35 inches (90 cm) on the Yenisey Ridge.
- Since the light snow offers little protection. The dirt and subsoil are solidified to an extensive depth for significant stretches over the vast majority of the basin. Permafrost is common in the north of the Lower Tunguska.
PLANT AND ANIMAL LIFE
- A large portion of the basin is secured with taiga (boggy, mainly coniferous backwoods), with Siberian tidy, fir, and cedar prevailing in the south and the more remote north.
- In Mongolia, Transbaikalia, and Tyva, there are steppe meadows, bounded in the far south of the Selenga River basin by semidesert.
- In the most distant north of the basin, taiga is superseded by tundra (boggy plain secured with greenery and other low, cold-tolerant plants).
- The Yenisey and its tributaries are rich in fish: the mountain surges of the headwaters support grayling, trout, lenok, insect, and dace.
- The lower stretch of Yenisey is supported in summer by transient waterfowl from the south, the little lakes and islands support ducks, geese, and swans, and the muskrat that has adapted to living in the channels of the delta.
