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.

"This was the Naryn River, the headwaters of the ancient Jaxartes, on whose lower reaches (the Syr Darya) Russia already stood firmly. We wandered for another two hours between the Naryn's sources, but I didn't dare descend its valley: our horses were exhausted and wounded; with me, besides Kosharov, were only three Cossacks and two Karakirghiz."

Rafting on Naryn River in Kyrgyzstan.

Naryn River (Alabugatuz; according to available information, "Alabugatuz" is not a separate tributary, but rather refers to parts or features of Naryn River) flows through Issyk-Kul, Naryn, Talas, and Jalal-Abad regions of Kyrgyz Republic and Namangan region of Republic of Uzbekistan.

The river flows through intermountain valleys and, in places, through narrow mountain gorges (the width of the river in these areas is 30-40 meters, and 45 meters near the city of Naryn). Below the confluence of the Maly Naryn River, the river flows in a wide valley (the Naryn Basin).
The river is 807 kilometers long, with a drainage basin area of ​​59,100 sq. km. The average discharge is 429 cubic meters per second. The Naryn basin extends latitudinally. The basin is bounded by the Terskey, Kyrgyz, and Talas Ala-Too ranges to the north, and by the Atbashi and Fergana ranges to the south.
The discharge at the confluence of the Greater and Lesser Naryns is 90 cubic meters per second. The average annual discharge at the city of Naryn is 88.4, while in the Fergana Valley it is 432, with the highest being 963 cubic meters per second.
The average annual water discharge at Uch-Korgon is 365 (the annual river discharge is 11.5), with a maximum discharge of 1908 and a minimum of 21.2 cubic meters per second. The average water discharge at the river mouth is 480, with a maximum discharge of 2820 cubic meters per second.
Suspended sediment load is 760 kg/s. The Naryn River's waters are used for irrigation. The Great Fergana Canal begins in the Naryn. It freezes from the second ten days of January (ice cover thickness 80-120 cm) until the end of March - early April, ice drift lasts for several days.
The average long-term discharge of suspended sediment near the city of Uch-Korgon is 500 kg/s (15.8 million tons per year). The water is used for irrigation. The Northern Fergana Canal begins from the Naryn River. After the confluence, the Naryn Valley's character frequently changes: wide, flat sections of the river give way to narrow canyons and gorges, filled with rapids and very turbulent currents.
In its upper reaches, the Naryn is a glacial-snow-fed river, with high summer runoff characteristic of this type. Downstream, due to the lowering of the catchment area and changing feeding conditions, the annual flow distribution gradually changes.
Flood season lasts from April to August. Maximum flow occurs in June and July. In its upper reaches, the river freezes. The river's water salinity ranges from 200 to 500 mg/l, increasing toward its mouth, especially during low water. Receiving numerous tributaries, the main ones being the Atbashi and Alabuga on the left, and the Kekjerty and Kökömeren on the right, the Naryn cuts through the Fergana Range.
Entering the Fergana Valley, the Naryn loses its mountain river character and, flowing along its alluvial fan, breaks into branches, forming a pebble floodplain up to 3.5 kilometers wide. Within the Fergana Valley, the Naryn merges with the Karadarya to form the Syr Darya River.
The river is formed entirely within Kyrgyzstan by melting glaciers and snow, with a perennial flow of 23.7 billion cubic meters. There are 750 glaciers in the Naryn basin, covering a combined area of ​​over 1,000 square kilometers. Kyrgyzstan ranks fifth in the world in terms of hydroelectric resources.
The river has significant energy resources. The Toktogul, Tash-Kumyr, Uchkurgan, Kurpsai, and Shamaldysai hydroelectric power plants are located on it. The Kambaratinskaya-2 hydroelectric power plant is under construction, as well as the Upper Naryn hydroelectric power station cascade with associated reservoirs.
The cities of Naryn, Tash-Kemur, and Uch-Korgon (Uzbekistan) are located on the river's banks. The Toktogul Reservoir is located on the river. The Naryn River is formed by the confluence of the Karasai, Taragai, Ekurgen, and Dzhaman-Echki rivers, which originate in the Inner Tien-Shan in the Terskey Ala-Too, Jetim, Jetim-Bel, and Borkoldoy ranges, and partly in the Ak-Shyirak range of the Central Tien-Shan.
The main components of the Naryn River are the Kum-Tor, which flows from the western glaciers of the Ak-Shiyrak Range – the Petrov, Akbel, and Lysyi Glaciers. These glaciers descend to an altitude of 3,730 meters above sea level (the elevation of Lake Petrov) and form powerful ice flows.
The Western Petrov Glacier is 10 kilometers long, while the Eastern Petrov Glacier extends for 12.5 kilometers. The Naryn River basin contains 2,074 glaciers, covering a total area of ​​1,357.8 square kilometers. Merging with the Ara-Bel-Suu River, it forms the Taragai River.
The confluence of the Taragai and Dzhaman-Echki Rivers in the eastern Jetim Range, the western spurs of the Ak-Shiyrak Range, and the northern slopes of the eastern Chakyr-Korum Range form the Naryn River.

Geographic coordinates of formation of Naryn River are: N41°36'24 E77°43'16

Vast syrts are located in upper reaches of the Naryn River.

The syrts of the upper reaches of the Naryn River are wide buried valleys, partially filled with moraine and fluvioglacial deposits. Numerous glacial boulders cover their surface, and small lakes of moraine origin are common. Numerous streams flow through the valleys, creating, due to permafrost, swampy soil in the lower reaches.
In general, the szyrts of the upper Naryn River are wide, high-mountain valleys (3,600-3,700 m. a. s. l.), with a gently rolling topography, covered with lush grassy vegetation, and completely devoid of forest. The Naryn State Nature Reserve, covering 91,023.5 hectares, is located in the upper reaches of the river, where the Tien Shan maral population is protected and restored.
