Naryn river.

Sights of Naryn River.

“The Naryn River flows south, southwest to the tip of low mountains running along the left bank, its valley is swampy and flat: after passing 8 versts, the road crosses the river, heads south, the terrain rises, hilly, consists of deep pits filled with bitter water, the ground is hard and brackish, then the road goes westward along a dry bed of a stream flowing from the above mountains. The left bank of the Naryn overlooks the valley of the Karasai River.

Rafting on Naryn River in Kyrgyzstan.

Naryn River is formed from the confluence of the rivers: Karasai, Taragay, Ekurgen, Jamanechki, originating in the Inner Tien Shan from the Terskey Ala-Too, Akshiyrak, Jetim, Jetim-Bel, Borkoldoy ridges. The main components of the Naryn River - Kum-Tor, flows from the western glaciers of the Akshiyrak ridge - Petrov, Akbel, Lysy.
Glaciers descend to a height of 3730 meters above sea level (the height of Petrov Lake) and are powerful ice flows. The length of the Western Petrov glacier is 10 kilometers, the length of the Eastern Petrov glacier reaches 12.5 kilometers.
The river flows through the territories of Issyk-Kul, Naryn, Talas and Jalal-Abad regions of Republic of Kyrgyzstan and Namangan region of the Republic of Uzbekistan. The length of the river is 807 kilometers, the basin area is 59.1,000 square kilometers.
The average water flow is 429 cubic meters per second. The Naryn basin is elongated in the latitudinal direction. From the north, the basin is limited by the Terskey, Kyrgyz and Talas Ala-Too ridges, in the south by the Atbashi and Ferghana ridges.
The water flow at the confluence of the Big and Small Naryn is 90 cubic meters per second. After the confluence, the nature of the Naryn valley often changes - widened flat sections of the river are replaced by narrow canyons and gorges, in which rapids abound and very stormy currents.
The average flow of water at the mouth of the river is 480 cubic meters per second, the maximum flow is 2820 cubic meters per second, suspended sediments are 760 kg/s. In the upper reaches, the Naryn belongs to the glacier-snow fed rivers with a high summer flow characteristic of this type.
Downstream, due to a decrease in the height of the watershed and a change in feeding conditions, the intra-annual distribution of runoff is gradually changing. The Big Ferghana Canal starts from Naryn. High water from May to August. Maximum flow in June and July.
In the upper reaches the river freezes. The mineralization of water is 200 - 500 mg/l, it increases towards the mouth, especially during low water. In the upper reaches of the river there is the Naryn State Reserve with an area of ​​91023.5 hectares.
Taking a large number of tributaries, the main of which are the Atbashi, Alabuga - on the left, Kekdzherty and Kökemeren - on the right, the Naryn cuts through the Ferghana Range. Having entered the Fergana Valley, the Naryn loses the character of a mountain river and, flowing along its alluvial fan, breaks into branches and forms a pebble floodplain up to 3.5 kilometers wide.
Within the Ferghana Valley, the Naryn merges with the Karadarya and forms the Syrdarya river. The river has significant energy resources, it contains: Toktogul, Tash-Kumyr, Uchkurgan, Kurpsai, Shamaldysai HPPs, the Kambarata HPP-2 and the cascade of Upper Naryn HPPs with the corresponding reservoirs are being built.
On the banks of the river there are cities: Naryn, Tash-Kumyr, Uchkurgan. On the river is the Toktogul reservoir. In the upper reaches of the Naryn River there are extensive syrts. The syrts of the upper reaches of the Naryn River represent wide buried valleys partially filled with moraine and fluvioglacial deposits.
Numerous glacial boulders cover their surface; small lakes of moraine origin are often found. Numerous streams flow through the valleys, creating, due to permafrost, waterlogging of the soil in the lowest places. In general, the syrts of the upper reaches of the Naryn are wide, high-mountain (3600 - 3700 meters above sea level) valleys, with a slightly hilly relief, covered with rather juicy grassy vegetation, completely devoid of forests.
