The main river of the Altai region is the Ob. Rivers of Altai on the map Small rivers of Altai

The rivers of the Altai Territory mainly belong to the Ob system. In the west and north-west of the region there is an area of ​​internal drainage - the drainless basin of the Kulundinskaya Lowland.

The Altai region crosses in its upper reaches the Ob River. At a distance of 500 km, its wide ribbon forms two giant bends. Ob and its tributaries Chumysh, Aley, Big River , Barnaulka and others have a calm flow, wide developed valleys, in which strongly winding river beds lie, with clearly visible sandy reaches.

The river network in the Altai Mountains, with the exception of the southeast, is well developed. Rivers start from glaciers and numerous lakes. On some flat watersheds there are swamps that give rise to rivers (Bashkaus - a tributary of the Chulyshman). Mountain rivers flow in narrow valleys, sometimes in dark, gloomy gorges. Along a rocky channel strewn with boulders and pebbles, the water rushes down with a large fall, encounters hard crystalline ledges and rapids along the way, breaks against them, turning into white bubbling foam. The noise of the rapids gives way to the roar of waterfalls, of which there are many in the Altai highlands.

The picture of thundering water falling in ledges from a height of tens of meters is amazing. The highest and most beautiful waterfalls are located on the slopes of the Belukha massif. On the northern slope along Tekel (the right tributary of the Akkem) there is a waterfall 60 m high; on the Tigirek (the left tributary of the Kucherla) there is a waterfall of 40 m. On the southern slope of Belukha, in the upper reaches of the Katun, on its right tributary, there is the Rossypnaya waterfall, 30 m high. There are dozens of waterfalls on the rivers flowing into Lake Teletskoye. The Korbu waterfall is well known; its powerful stream falls from a 12-meter height.

The rivers of the Altai Territory have a mixed supply: rain, snow, glaciers and groundwater.

The rivers of the Kulundinskaya Lowland are predominantly fed by snow. They are characterized by spring floods. Very little in summer atmospheric precipitation, rivers become very shallow and dry up in many places. By the end of summer, there is almost no water left in the upper reaches of the Kuchuk River; the channel represents chains of small elongated lakes.

Ob- a lowland river, but its sources and main tributaries are in the mountains, therefore, in the diet and regime of the Ob, signs of lowland and mountain rivers are observed. The Ob has two maximum water rises - in spring and summer. The spring rise in water occurs from the melting of snow, and the summer rise from the melting of glaciers. Most low level water in the Ob in winter.

Low water in winter is typical for most rivers in the region. Rivers freeze for a long time. Freeze-up on the Ob and rivers of the plains begins in the second half of November; by the end of April they are free of ice.

Mountain rivers belong to the Altai type, which has a special regime and nutrition. First of all, they are rich in water, since they have food sources that continuously replenish water supplies from precipitation, melting glaciers and the influx of groundwater.

Snow melts in the mountains for several months, from April to June. The second feature of snow melting is that the snow melts first in the north Gorny Altai in the lowlands, and then in the middle mountains and finally in the southern highlands. In June, snowfields and glaciers begin to melt. Sunny clear days alternate with rainy ones. There are years with long summer rains. Precipitation often falls in the form of showers, and the water level in rivers rises quickly and strongly. The rivers of the highlands are fed by snow and glaciers and therefore are characterized by a summer, namely June, rise in water. Autumn floods occur. In four to five months, most of the annual water requirement flows down.

Picture of maximum level Water in a river is determined by hydrography. Altai rivers can be roughly divided into five groups.

1. Rivers with spring floods. Snow food. This group includes medium and small rivers in the foothills with an average drainage height of up to 500 m.
2. Rivers with spring floods and rain floods. This group includes medium and small rivers with average height catchments from 500 to 1500 m.
3. Rivers with spring-summer floods and rain floods. Food: snow, glaciers, rain. This group includes all large and medium-sized rivers with a drainage height from 1500 to 2500 m.
4. Rivers with summer floods. The food is glacial. These are mainly medium and small rivers at altitudes above 2500 m.
5. Rivers with equalized flow throughout the year. Ground nutrition. These are mostly small rivers.

The greatest groundwater recharge is observed on rivers with an average catchment height ranging from 600 to 2000 m. The exception is the Chuya River, in which the share of groundwater is 33% of the annual flow. This is due to the fact that the Chuya depression, filled with sand and pebble deposits, is a huge reservoir of groundwater that gradually flows into the Chuya.

The duration of freeze-up on Altai rivers ranges from 110 to 200 days, and in some sections of the rivers the water does not freeze. The beginning of freeze-up usually occurs in November, the opening - at the beginning - mid-April.

Belukha is not only a glacial junction, but also the most important feeding center for large and small rivers spreading from Belukha in different directions. The Belukha glaciers are very active in this regard, because they end low, which means they melt a lot and at the same time receive a lot of precipitation. According to the available hydrometric data, the first place in terms of water content belongs to the Iedygem River, the second and third are the Katun and Bereli, then the Ak-kem and Myushtu-airy. The total flow of glacial waters provided by Belukha is estimated at approximately 400 million cubic meters. m. per year. This entire mass of water is taken at an altitude of about 2000 m and, therefore, has a huge potential reserve of power.

Characteristics of Altai rivers

One of the most powerful rivers of the Altai Mountains is the Biya River. It flows from Lake Teletskoye, and together with another large river, the Katunya, merges into great river Ob. The Biya is a mountain-plain river; along its entire length there are practically no widenings of the channel. This current makes it convenient for tourist rafting.

At its sources, the river is surrounded by rocks, and then it emerges into flatter places, the banks are covered with bright greenery, trees, and flowers. The total length of the river is 301 km.

Chibitka River

The Altai Republic is filled with many picturesque natural sites. Among them is the Chibitka River, stretching for 39 kilometers along the Ulagan Plateau. The river originates on the slopes of the Kuraisky ridge.

The route along Chibitka is very popular among motorist travelers. Following the river, you can see many picturesque places. Among them are lakes Uzunkel and Cheybekkel, as well as the “Red Gate” - a narrow isthmus between the mountains, which has a reddish tint.

There are a total of 20 lakes in the Chibitka basin. There are two villages near the river - Aktash and Chibit.

Ursul River

The Ursul, the left tributary of the Katun River, is one of the most beautiful rivers in the Altai Territory, attracting tourists with its pristine landscapes and the opportunity to test themselves in water slalom.

Originating on the northern slopes of the Terektinsky ridge, the Ursul River is wide and calm in its middle reaches. Winding among the gentle banks, the river does not show its obstinate temper. Narrow strips of willow, birch and larch frame the coastline. The river becomes completely different in its lower reaches when it flows into the Katun: a seething stream will roar among the steep rocks, rolling over huge boulders that cut the Ursul into separate streams. This is where thrill seekers go. They gave their names to the river rapids: “Target”, “Chernaya Yama”, “Khabarovsk Hydroelectric Power Station”, “Castle”. Ursul rafting is becoming more and more popular among rafters every year.

But the river attracts not only its natural beauties. Along the banks of the Ursul there are many mounds of the 5th-3rd centuries BC, where during excavations daggers, arrowheads made of bone and bronze, as well as inlaid belts, bronze mirrors, and decorations for horse harnesses were found. Along the tributaries of the Ursula, in the surrounding tracts, you can come across stone women depicting warriors with painted faces and details of clothing and jewelry.

The Ursul River is an ideal holiday destination for mountain lovers, wildlife, history and unforgettable adventures.

Charysh River

The Charysh River is one of largest rivers Mountain Altai. The length of the river is 547 kilometers, and its source is located in the Ust-Kansky region of the Altai Mountains, on the northern slopes of the Korgon ridge with altitudes of more than 2000 meters.

On the cozy picturesque shores you can find convenient places for summer parking and tent camps. The banks either clamp the rivers in a vice, or diverge and allow the water of the rivers to calm down, and the earth to spread out into valleys filled with flowers and herbs. Spruce and fir grow along the slopes of the Korgon ridge; higher up there begins a zone of high-mountain meadows with low but bright herbs. Also on the banks of the river you can see many different shrubs, including berry bushes: black and red currants, raspberries, honeysuckle, rowan, viburnum.

The Charysh and its tributaries are famous among rafting enthusiasts. The link of the rivers Kumir - Charysh - Korgon - Charysh is a route of the 5th category of difficulty. This is the only water “five” in the Altai Territory

Fans of archeology and history of ancient times can visit caves in the vicinity of the village of Ust-Kan and on the banks of the Charysh in the middle reaches, where traces of ancient people have been found.

Chemal River

The Chemal River is a mountain river originating in the mountains of the Chemal region of the Altai Territory. There are several tourist centers located along its bed.

Chemal descends from a height of 2000 meters, taking its source in a lake located on the Tamanelen mountain range, at a distance of 95 kilometers from Gorno-Altaisk. The name of the river can be translated from the Altai language as “ant river”. Chemal – the only river in a region whose flow was stopped by a hydroelectric power station built in 1935. The majestic view of the confluence of the Chemal and another river called the Katun can be seen in the main guidebooks to Altai. This place is also called the “Gate of Sartakpai” - named after the legendary Altai hero.

Mild climate, many warm sunny days And Nice weather favor the development of resort tourism in the Chemal region.

Peschanaya River

The Peschanaya River is a left tributary of the Ob, flowing in the Altai Territory. The river flows picturesquely from the mountains, flowing through rapids and dividing into channels, and then joining into one channel. Thus it flows rapidly, calming down only in the valley. It flows along a channel of 276 kilometers.

The river is very popular among tourists and lovers of nature and water sports. It contains rocks and sandbanks, screes and steep bomes, as well as many rapids.

The river is also a route of the third category of difficulty, where water tourism competitions are held annually.

The mouth of the river is a unique natural monument, as this place is very picturesque. This place is home to a huge number of bays and lakes, on the shores of which waterfowl nest.

You can get here by horse or boat.

Katun River in Gorny Altai

The Katun River is the largest river in the Altai Mountains. Its name goes back to the Altai word “kadyn”, which means “mistress”, “mistress”. The length of the river is 688 kilometers.

The river originates on the southern slopes of the Belukha mountain massif, crosses the basin of the Uimon steppe, and after flowing into the Argut River flows in a northerly direction. The river is formed by numerous streams and rivers that flow from mountain ranges. The main tributaries of the river are Chuya, Kuragan, Koksa, Kucherla, Akkem, Ursul, Argut, Sumulta, Isha, Maima, Kadrin, Sema. The most powerful tributary of the river is the Argut, which has a length of more than 230 kilometers.

The river bottom is filled with boulders and pebbles, and there are also frequent bedrock outcrops that form many rapids and waterfalls. In summer, the water in the upper reaches of the Katun acquires a milky white color due to the melting of glaciers, and in the fall the river turns turquoise.

In ancient times it was used as food and also served as amulets and talismans.

Altai region

Officially. Altai Territory is located in the southeast Western Siberia, 3419 km from Moscow. Territory 168,000 square km.

Informally. The Altai region is very large and diverse. The topography changes as you move through the area. He seems to be a growing bear, at first quiet and calm, then huge and majestic. This is how steppes and plains grow into foothills and mountains.

Officially. The climate is temperate continental, formed as a result of frequent changes in air masses.

Unofficially. The four seasons have many variations, and come back each year to see a different perspective. You can come in the hot summer, or you can come in the cool and rainy weather. Give me variety! - this is the main rule of Altai weather.

Summer and Altai Mountains

Officially: Altai Mountains are very complex system the highest ranges in Siberia, which are separated by deep valleys of mountain rivers and vast basins located inside the mountains.

Informally: The nature of Altai is amazing. Tourists from all over the globe rush to these places to enjoy beautiful views high mountains, mountain rivers, mysterious caves and deserted spaces. Immerse yourself in the tranquility and beauty of these places.

The settlement of the Altai Territory has begun
in the 18th century

Young Russia needed metal to produce weapons and coins. The Ural factory owner Akinfiy Demidov founded the first metallurgical plant in 1729 - Kolyvano-Voskresensky. The depths of Altai were also rich in silver. In 1744, Demidov began producing silver. The result of Akinfiy Demidov’s activities in the Altai region was the establishment of a feudal mining industry based on the serf labor of assigned peasants and artisans.

Event tourism in the Altai region

The creation and development of bright, interesting events in the business, cultural, and sports life of the Altai Territory has become the basis for the development of event tourism in the region. The region annually hosts more than a dozen festivals, forums, and holidays that can attract thousands of tourists from various regions of Russia and from abroad. These are the International Tourism Forum “VISIT ALTAI”, the festival “Blossoming of the Maralnik”, the drinks festival “Altaifest”, the Day of Russia at the “Turquoise Katun”, the festival “Shukshin Days in Altai”, the International Youth Forum of the Asia-Pacific Region, the SCO Forum, the Siberian international forum on health and medical tourism, the Altai Wintering holiday and many others.

beauty and health

Officially. The useful flora of the region has 1184 plant species. The most large group drugs, including about 100 types widely used in official medicine.

Informally. Decoction, herbal teas, berry fruit drinks - this is what everyone who comes to the Altai Territory should try. Spas, health and wellness centers use products made from Altai herbs.

Altai is characterized by a large number of rivers. Their total number is about 20 thousand. If you combine all the rivers of Altai into one, then its length will be enough to go around Earth along the equator one and a half times. Since the Altai region is characterized by a diverse landscape (there are mountains, valleys and lowlands), the rivers also differ in the nature of their flow. These are both stormy mountain streams and calm, slow currents.

The distribution of rivers and lakes in these places is determined by the nature of the terrain and climate. So, water system For these reasons, the edge is divided into two parts:
The rivers of the mountain range mainly belong to the Upper Ob basin. This is the Altai mountain range, its foothills, the entire Right Bank. Here the Ob River collects the bulk of its water. Its tributaries, both on the left and on the right, are about 2000 rivers, the length of each is up to 10 km, their density is 1.5 - 2 km;
Plain streams belong to the drainless Kulunda depression. These are calm rivers, in the beds of which many freshwater lakes are formed. The Kulunda depression is also distinguished by the presence of salty and bitter-salty lakes.

Nutrition of Altai rivers
The Ob River is considered the main water-bearing artery of this region. It is formed after the merger of Biya and Katun. It flows first through mountainous areas, where it is fed by numerous tributaries. In the valley, the nature of its flow changes and it resembles a deep, calm stream. Here its main tributaries are the Chumysh, Alei, Bolshaya Rechka, Barnaulka, which are characterized by wide valleys and sandy reaches.
The rivers of the mountainous part have glacial, snow and partly rain. Ground nutrition is poorly expressed. It is typical only for lowland rivers.

Since the Altai region differs in tectonic structure, the nature of the river flows here is also diverse. Mountain arteries are turbulent, rapid streams of water, with rapids and steep banks. The presence of tectonic ledges causes a large number of waterfalls (waterfalls on the slopes of the Belukha massif, on the northern slope along Tekel, on Tigirek). The most picturesque waterfall is considered to be Rossypnoy, 30 m high, which is located on the southern slope of Belukha, in the upper reaches of the Katun.
Plain rivers characterized by wide valleys, calm currents, a large number of floodplains and above-floodplain terraces.

Regime of Altai rivers
The flow regime of Altai rivers largely depends on climatic conditions. Since their main diet is melt water, spring floods are typical for the Altai rivers. It lasts 10-12 days in the mountain range, and much longer on the plain. After it, the rivers become sharply shallow.

The freezing of rivers in the valley begins in October-November and lasts about 170 days. Ice drift begins in mid-April. Many rivers, especially shallow ones, freeze to the bottom. But on some (rivers Biya, Katun, Charysh, Peschanaya) the flow of water continues and in some places the water comes to the surface, forming glaciers. Fast-flowing rivers - Katun, Biya, Bashkaus, Chuya - partially freeze. On sharp turns and descents, cascading ice forms here, and hanging ice on the waterfalls, which are distinguished by their extraordinary beauty.

The Ob is the main aquifer artery of the Altai Territory and has a mixed supply (snow (49%) with a noticeable share of rain (27%)). The basin area is 3 million m², length – 453 km. Flood on the river lasts about 120 days, observed mainly in spring and partly in autumn, the water level rises by 1-8 m. The river flows into the Ob Reservoir.
Biya is the second largest river here. The Biya begins from Lake Teletskoye, but its own sources are located far in the southeast, where Bashkaus and Chulyshman begin in the spurs of the Chikhachev ridge. Its major tributaries are the Lebed, Sarykoksha, Pyzha, and Nenya rivers. The length of the river is 300 km.
