Lakes of Kyrgyzstan: Geography, Major Lakes and Alpine Lake Systems
Introduction: Why Kyrgyzstan Is a Country of Mountain Lakes
Kyrgyzstan is one of the most mountainous countries in the world. Nearly ninety percent of its territory consists of mountain terrain shaped by the Tian Shan and Pamir-Alay systems. This rugged relief, together with widespread glaciation, enclosed intermontane basins, and active geological processes, created one of the most distinctive lake landscapes in Central Asia.
Although the country is most often associated with Issyk-Kul, the lake geography of Kyrgyzstan is far broader and more complex. The national lake system includes around 1,900 lakes, ranging from vast tectonic basins to small alpine and glacial lakes hidden among high ridges and remote valleys. Some occupy deep structural depressions formed by tectonic movements, while others originated through glacial retreat, moraine damming, or landslides that blocked mountain rivers.
This combination of lake types makes Kyrgyzstan unusual. A small number of large lakes account for most of the total water surface, while the overwhelming majority are small mountain lakes scattered across high-altitude terrain. Many of them lie above 3,000 meters above sea level and remain frozen for much of the year. In the highest parts of the Tian Shan, glacial and moraine-dammed lakes often occur in clusters, especially in valleys shaped by former or modern glaciers.
In physical-geographic terms, the lakes of Kyrgyzstan can be divided into several broad categories. The first includes large tectonic lakes occupying major mountain depressions. Issyk-Kul, Son-Kul, and Chatyr-Kul belong to this group and dominate the country’s lake geography in terms of surface area. A second group includes glacial and moraine-dammed lakes, which are especially common in the high mountain belts of the Tian Shan. A third category consists of landslide-dammed lakes created when rockfalls or slope collapse blocked river valleys and trapped water behind natural barriers.
Elevation is one of the key factors controlling this distribution. Lower basins contain only a few large permanent lakes, whereas much of the high-mountain zone is dotted with small alpine and glacial lakes formed by snowmelt, glacier activity, and enclosed terrain. As a result, Kyrgyzstan’s lake geography is inseparable from its mountain hydrology. Lakes, glaciers, rivers, and seasonal meltwater together form a connected water system that supports both local ecosystems and major downstream river networks across Central Asia.
Understanding the lakes of Kyrgyzstan therefore means looking beyond famous destinations and seeing them as part of a larger mountain landscape shaped by geology, climate, and high-altitude hydrology. The sections below examine how many lakes exist in Kyrgyzstan, which are the largest, how different lake types form, and how lake clusters are distributed across the mountain ranges of the Tian Shan and Pamir-Alay.
How Many Lakes Are in Kyrgyzstan?
According to statistics published by the National Statistical Committee of the Kyrgyz Republic, the country contains approximately 1,923 lakes with a combined water surface of about 6,836 km². These lakes form part of a much larger national water system that also includes more than 3,500 rivers and dozens of underground water reserves.
Most of these lakes are not large water bodies like Issyk-Kul. On the contrary, the overwhelming majority are small alpine and glacial lakes scattered across remote mountain valleys and plateaus. Many are only a few hectares in size, and some are seasonal rather than permanent. This means that the lake geography of Kyrgyzstan is defined less by the number of major lakes and more by the density of small high-mountain lakes.
Taken together, the lakes of Kyrgyzstan cover roughly 6,800 square kilometers of water surface. However, that figure is heavily dominated by Issyk-Kul alone. Once the area of Issyk-Kul is removed, the rest of the national lake system consists mostly of relatively small lakes located at medium or high elevations.
Despite the large number of lakes, the overwhelming majority of lake water is concentrated in a single basin. Hydrological estimates show that more than 99% of the total lake water volume of Kyrgyzstan is contained in Issyk-Kul alone, making it the dominant feature of the national lake system.
Key Hydrological Facts
Lakes form only one part of Kyrgyzstan’s broader water geography. The country also contains thousands of rivers and streams, major glacier systems, and important underground water reserves. Together these resources make Kyrgyzstan one of the key freshwater source regions of Central Asia.
| Indicator | Approximate Value |
|---|---|
| Total lakes | 1,923 |
| Total lake surface area | ~6,836 km² |
| Rivers and streams | 3,500+ |
| Underground water deposits | 44 |
| Total lake water volume | ~1,745 km³ |
| Share of water in Issyk-Kul | ~99% |
| Glaciers | ~9,900 |
Because of its glaciers, rivers, and high mountain lakes, Kyrgyzstan functions as an important water source for Central Asia. Many rivers originating in the Tian Shan mountains contribute to major regional systems such as the Syr Darya basin.
These figures show why Kyrgyzstan is often described not only as a mountain country, but also as a major water-storage region for Central Asia. Snowfields and glaciers feed rivers and lakes, while large basins such as Issyk-Kul and Son-Kul act as important natural reservoirs within the wider mountain hydrological system.
Why Most Lakes Are Small
One of the main characteristics of Kyrgyzstan’s lake system is the small average size of most lakes. Only a limited number of lakes exceed one square kilometer in area, while the rest are much smaller alpine basins formed under mountain conditions.
Hydrological inventories show that only a small fraction of Kyrgyzstan’s lakes exceed one square kilometer in area. The vast majority are small alpine lakes formed in glacial or mountain basins.
There are several reasons for this pattern:
- Glacial erosion: retreating glaciers often leave behind small basins that later fill with meltwater.
- Steep relief: narrow valleys restrict the formation of large open basins.
- Active mountain processes: landslides, rockfalls, and debris dams frequently create irregular lakes of limited size.
- High-altitude climate: some lakes are seasonal or remain ice-covered for long periods.
As a result, Kyrgyzstan’s lake geography is shaped by contrast. The country has only a few dominant large lakes, but also an exceptionally dense network of small high-altitude lakes. That combination is one of the defining features of its physical geography.
It is also worth noting that totals may vary slightly from one source to another. Some inventories count only permanent lakes above a certain size, while others include seasonal glacial basins or temporary meltwater lakes. Even so, the overall conclusion remains the same: Kyrgyzstan contains one of the most extensive mountain lake systems in Central Asia.
Statistical figures are based primarily on official publications of the
National Statistical Committee of the Kyrgyz Republic and regional water resource reports.
The Largest Lakes of Kyrgyzstan
Although Kyrgyzstan has nearly two thousand lakes, only a handful are truly large. In terms of surface area, the national lake system is dominated by a very small number of major basins, above all Issyk-Kul. Most other lakes are relatively small and are better understood as alpine, glacial, or regional mountain lakes rather than as major inland water bodies.
The three largest lakes — Issyk-Kul, Son-Kul, and Chatyr-Kul — form the core of Kyrgyzstan’s lake geography. Together they account for most of the country’s total lake area. Beyond them lies a second group of smaller but geographically notable mountain lakes, including glacial, landslide-dammed, and seasonal alpine lakes found across the Tian Shan and Pamir-Alay.
Largest Lakes of Kyrgyzstan
| Lake | Area (km²) | Elevation (m) | Maximum Depth (m) | Type | Region |
|---|---|---|---|---|---|
| Issyk-Kul | 6,236 | 1,607 | 668 | Tectonic / Endorheic | Issyk-Kul Basin |
| Son-Kul | ~278 | 3,016 | ~13–14 | High-altitude tectonic basin | Naryn Region |
| Chatyr-Kul | ~175–181 | ~3,530 | ~16–20 | High-altitude basin lake | At-Bashy Region |
| Sary-Chelek | ~4.7–4.9 | 1,873 | 234 | Landslide-dammed | Chatkal Mountains |
| Kel-Suu | ~4–5 | ~3,500 | Unknown | Alpine basin lake | Kok-Kiya Valley |
| Kulun | ~3 | ~2,850 | Unknown | Glacial | Alay Mountains |
| Ala-Kul | ~1.5 | 3,532 | Unknown | Glacial | Terskey Ala-Too |
| Kol-Ukok | ~1–2 | ~3,000 | ~17 | Glacial | Naryn Region |
Beyond the main large basins, Kyrgyzstan also contains many smaller lakes that are important for mountain geography, glaciology, biodiversity, and tourism. While they are modest in size, several are among the country’s most recognizable alpine landscapes.
Notable Alpine and Mountain Lakes
| Lake | Approximate Area (km²) | Elevation (m) | Type | Why It Stands Out | Region |
|---|---|---|---|---|---|
| Ala-Kul | ~1.5 | 3,532 | Glacial | One of the best-known trekking lakes in Kyrgyzstan | Terskey Ala-Too |
| Kol-Ukok | ~1–2 | ~3,000 | Glacial | High-altitude lake in a broad mountain pasture landscape | Naryn Region |
| Tulpar-Kol | ~1 | ~3,500 | Glacial | Scenic lake below Lenin Peak in the Pamir-Alay | Trans-Alay |
| Petrov Lake | ~1 | ~3,730 | Glacial / Moraine-dammed | Important for glacier and hydrology studies | Ak-Shyyrak Massif |
| Merzbacher Lake | Seasonal, variable | ~3,300 | Ice-dammed | Fills and drains periodically; major glaciological site | Central Tian Shan |
| Kel-Suu | ~4–5 | ~3,500 | Alpine basin lake | Dramatic cliff-sided setting in a remote high valley | Kok-Kiya Valley |
| Sary-Chelek | ~4.7–4.9 | 1,873 | Landslide-dammed | Deep forest lake within a biosphere reserve | Chatkal Mountains |
| Kulun | ~3 | ~2,850 | Glacial | One of the best-known mountain lakes of southern Kyrgyzstan | Alay Mountains |
Issyk-Kul: The Dominant Lake Basin
The central feature of Kyrgyzstan’s lake geography is Issyk-Kul. With a surface area of more than 6,200 square kilometers, it is by far the largest lake in the country and one of the largest high-altitude lakes in the world. It occupies a vast tectonic basin between the Kungey Ala-Too and Terskey Ala-Too ranges and contains the overwhelming majority of Kyrgyzstan’s total lake water surface.
Issyk-Kul is also unusual because it rarely freezes, despite its elevation and continental setting. Its great depth, slight salinity, and local hydrothermal influences help moderate winter ice formation. This is why the lake is traditionally known as the “Warm Lake.”
Son-Kul: The Great Lake of the High Plateau
The second largest lake, Son-Kul, lies on a high plateau in the Naryn region at an elevation of just over 3,000 meters above sea level. Unlike Issyk-Kul, it is shallow, strongly seasonal in character, and freezes during winter. In summer the surrounding basin becomes one of the best-known jailoo landscapes in Kyrgyzstan, with broad alpine pastures used for seasonal livestock grazing.
Chatyr-Kul: A Remote High-Mountain Basin
The third largest lake, Chatyr-Kul, lies in a remote basin near the Chinese border at an elevation of about 3,530 meters. It is one of the highest large lakes in Central Asia and represents a very different landscape from Issyk-Kul: cold, open, windswept, and semi-arid. Its isolation and altitude make it especially important as a wetland and wildlife habitat within the Inner Tian Shan.
Notable Medium-Sized and Alpine Lakes
Beyond the three dominant basins, Kyrgyzstan has a second group of smaller but well-known mountain lakes. These include Sary-Chelek, famous for its depth and forested setting in the western Tian Shan; Kel-Suu, known for its dramatic high-mountain scenery; and a number of glacial lakes such as Ala-Kul, Kol-Ukok, and Petrov Lake.
These lakes are not large in national hydrological terms, but they are geographically important because they illustrate the diversity of lake-forming processes in Kyrgyzstan. Some were shaped by glacial erosion, some by moraine dams, and others by landslides or enclosed alpine basins. Together they show that the country’s lake geography cannot be understood through Issyk-Kul alone.
Types of Lakes in Kyrgyzstan
The lakes of Kyrgyzstan were not formed by a single geological process. Instead, the diversity of lake types reflects the complex geological evolution of the Tian Shan mountains. Tectonic uplift, glacier activity, landslides, and erosion have all contributed to the creation of lake basins across the country.
For this reason geographers usually classify the lakes of Kyrgyzstan according to the origin of their basins. Some lakes formed millions of years ago through tectonic processes, while others appeared much more recently as glaciers retreated or mountain slopes collapsed. Understanding these formation processes helps explain why the country contains both enormous lakes such as Issyk-Kul and hundreds of much smaller alpine lakes scattered across high mountain valleys.
Tectonic Lakes
The largest lakes in Kyrgyzstan belong to the tectonic category. These lakes occupy structural depressions created by faulting and deformation within the Tian Shan mountain system. Over long geological periods these basins gradually filled with water from rivers, snowmelt, and underground sources.
The most important tectonic lakes include:
- Issyk-Kul
- Son-Kul
- Chatyr-Kul
Among these, Issyk-Kul is by far the largest and deepest. Its basin formed along major tectonic faults between two mountain ranges and gradually developed into one of the largest high-altitude lakes on Earth.
Glacial Lakes
Glacial lakes are the most widespread type of lake in Kyrgyzstan. They form in depressions carved by glaciers or in basins where meltwater accumulates behind natural barriers created by glacial debris.
Because Kyrgyzstan contains thousands of glaciers, glacial lakes occur throughout many high mountain regions, particularly in the central and eastern Tian Shan. These lakes are typically small and located at elevations above 3,000 meters.
Examples of well-known glacial lakes include:
- Ala-Kul
- Kol-Ukok
- Tulpar-Kol
- Petrov Lake
Many of these lakes are surrounded by moraines — ridges of rock debris left behind by retreating glaciers — which help create natural basins that retain meltwater.
Moraine-Dammed Lakes
A special type of glacial lake forms when a moraine acts as a natural dam across a valley. Water accumulates behind the debris ridge and gradually forms a lake.
Moraine-dammed lakes are common in glaciated valleys of the Tian Shan. While many remain stable for long periods, some can pose hazards if the natural dam becomes unstable.
In such cases the lake may suddenly drain in an event known as a glacial lake outburst flood (GLOF). These events can release large volumes of water and debris downstream within a short period of time.
Landslide-Dammed Lakes
Another group of lakes forms when landslides block mountain valleys. When large masses of rock collapse into a river valley they may create a natural dam that traps water upstream.
The best-known example in Kyrgyzstan is Sary-Chelek, located in the western Tian Shan mountains. The lake formed thousands of years ago when a massive landslide blocked a valley and created a deep enclosed basin.
Today Sary-Chelek lies within a protected biosphere reserve and represents one of the most scenic forest lakes in Central Asia.
Ice-Dammed Lakes
A rarer type of lake occurs when glacier ice itself forms a temporary barrier that traps meltwater. These ice-dammed lakes are often unstable because glaciers move and melt over time.
One of the most famous examples is Merzbacher Lake in the central Tian Shan. Each year the lake fills during the summer melt season and then drains suddenly through subglacial channels beneath the surrounding glacier.
This unusual cycle has made Merzbacher Lake an important research site for scientists studying glacier dynamics and mountain hydrology.
Elevation Distribution of Lakes in Kyrgyzstan
One of the defining characteristics of Kyrgyzstan’s lakes is their elevation. Unlike many regions of the world where lakes occur mainly in lowland basins, most lakes in Kyrgyzstan lie high in the mountains. This pattern reflects the country’s extreme topography, where much of the terrain rises above 2,000 meters above sea level.
Hydrological surveys indicate that roughly 84% of the lakes in Kyrgyzstan are located between 3,000 and 4,000 meters above sea level. This concentration reflects the strong influence of glacial and alpine processes in shaping lake basins across the Tian Shan.
Large lakes are relatively rare and usually occupy tectonic basins at moderate elevations. In contrast, the majority of lakes are located within the high-mountain belt of the Tian Shan, where glaciers, snowfields, and steep terrain create ideal conditions for the formation of alpine lakes.
Elevation Zones of Lakes
| Elevation Range | Typical Lake Types | Examples |
|---|---|---|
| 1500–2000 m | Tectonic basin lakes | Issyk-Kul, Sary-Chelek |
| 2000–3000 m | Mountain basin and landslide lakes | Kara-Suu, Kulun |
| 3000–3500 m | Plateau and glacial lakes | Son-Kul, Kol-Ukok |
| 3500–4000 m | High alpine glacial lakes | Chatyr-Kul, Ala-Kul |
| Above 4000 m | Small glacial ponds and seasonal meltwater lakes | Various lakes in the Central Tian Shan |
Distribution of Lakes by Elevation
| Elevation Range | Share of Lakes | Typical Lake Types | Characteristics |
|---|---|---|---|
| Below 2000 m | Very small share | Tectonic and landslide lakes | Includes large basins such as Issyk-Kul |
| 2000–3000 m | Moderate share | Mountain basin lakes | Often located in intermontane valleys |
| 3000–4000 m | Largest concentration (~84%) | Glacial and moraine-dammed lakes | Main alpine lake zone of the Tian Shan |
| Above 4000 m | Small but numerous | Small glacial ponds | Often seasonal meltwater lakes |
Highest Lakes of Kyrgyzstan
Many of Kyrgyzstan’s lakes lie at very high elevations in the Tian Shan and Pamir-Alay mountains.
Several well-known alpine lakes are located above 3,500 meters above sea level, making them
among the highest permanent lakes in Central Asia.
| Lake | Elevation (m) | Type | Mountain Region |
|---|---|---|---|
| Petrov Lake | ~3,730 | Glacial / Moraine-dammed | Ak-Shyyrak Massif (Central Tian Shan) |
| Ala-Kul | 3,532 | Glacial | Terskey Ala-Too |
| Chatyr-Kul | ~3,530 | High-altitude basin | At-Bashy Range |
| Kel-Suu | ~3,500 | Alpine basin lake | Kok-Kiya Valley |
| Tulpar-Kol | ~3,500 | Glacial | Trans-Alay Range |
These lakes illustrate the extreme altitude of Kyrgyzstan’s lake geography. Many are located
near major glacier systems or high mountain passes, and several remain frozen for much of the year.
Why High-Altitude Lakes Are So Common
- Glacial erosion: glaciers carve depressions in mountain valleys.
- Moraine barriers: glacial debris forms natural dams.
- Enclosed terrain: steep slopes create natural basins.
- Seasonal snowmelt: meltwater feeds many alpine lakes.
These conditions are particularly widespread in the central Tian Shan mountains, where glaciers remain active and continue to shape the landscape. As glaciers retreat, new lakes sometimes appear while existing lakes expand or change.
Glacial Lakes and Mountain Hydrology
Glacial lakes represent one of the most dynamic components of Kyrgyzstan’s lake system. While the largest lakes occupy tectonic basins, hundreds of smaller lakes are directly connected to glaciers and high-mountain hydrology.
The Tian Shan mountains contain thousands of glaciers that store snow and ice during winter and release meltwater during warmer months. This meltwater feeds rivers, streams, and alpine lakes throughout the region.
In total, Kyrgyzstan contains nearly 10,000 glaciers, which serve as natural water reservoirs in the high mountains. Seasonal melting of these glaciers feeds rivers, streams, and many alpine lakes throughout the Tian Shan mountain system.
As glaciers advance and retreat they leave behind complex terrain filled with rock basins, moraines, and natural dams. These features create ideal conditions for the formation of glacial lakes.
Major Glacial Lake Regions
- Terskey Ala-Too Range
- Kyrgyz Range
- Central Tian Shan (Ak-Shyyrak Massif)
- Kokshaal-Too Range
- Pamir-Alay Mountains
In these mountain regions glacial lakes often occur in clusters within the same valley system.
Largest Glacial Lakes of the Tian Shan
The Tian Shan mountains contain thousands of glacial and moraine-dammed lakes
formed by past and present glacier activity. Most of these lakes are small alpine
basins, but several are well known for their size, scientific importance, or
connection to major glacier systems.
| Lake | Approx. Area (km²) | Elevation (m) | Type | Mountain Region |
|---|---|---|---|---|
| Petrov Lake | ~1.0 | ~3,730 | Moraine-dammed glacial lake | Ak-Shyyrak Massif (Central Tian Shan) |
| Ala-Kul | ~1.5 | 3,532 | Glacial alpine lake | Terskey Ala-Too |
| Tulpar-Kol | ~1.0 | ~3,500 | Glacial lake | Trans-Alay Range (Pamir-Alay) |
| Kol-Ukok | ~1–2 | ~3,000 | Glacial lake | Naryn Region |
| Merzbacher Lake | Variable | ~3,300 | Ice-dammed glacial lake | Central Tian Shan (Inylchek Glacier) |
Kyrgyzstan contains thousands of glacial lakes, making the Tian Shan one of
the most lake-rich high-mountain regions of Central Asia.
Many other smaller glacial lakes occur throughout the Tian Shan, particularly in
the Central Tian Shan, Terskey Ala-Too, and Kokshaal-Too ranges. Because glaciers
continue to retreat in some regions, new lakes occasionally appear while existing
lakes expand or change shape.
Glacial Lake Outburst Floods
Some glacial lakes may pose natural hazards. When a moraine dam collapses or an ice barrier fails, a lake can drain suddenly in a glacial lake outburst flood (GLOF).
These floods release large volumes of water and debris downstream and may damage infrastructure or mountain roads. Because of this risk, several glacial lakes in Kyrgyzstan are monitored by scientists and hydrological agencies.
Glacial Lakes and Climate Change
Recent decades have seen noticeable changes in many glacial lakes across the Tian Shan. As glaciers retreat, new lakes sometimes appear in recently exposed valleys, while existing lakes may expand.
For researchers, glacial lakes therefore serve as indicators of environmental change in high mountain regions.
Why Kyrgyzstan Is Called the Water Tower of Central Asia
Because of its extensive mountain systems and large number of glaciers, Kyrgyzstan is often
described as the “water tower of Central Asia.” The high ranges of the Tian Shan store enormous
amounts of freshwater in the form of glaciers, seasonal snowfields, mountain lakes, and underground
water reserves.
These natural reservoirs play a crucial role in the regional hydrological system. During the
spring and summer melt season, glacier and snowmelt feed thousands of rivers that flow across
Central Asia. Many of these rivers ultimately contribute to the Syr Darya basin, one of the
largest river systems in the region.
The importance of Kyrgyzstan’s mountain water resources extends far beyond its national borders.
Water originating in the Tian Shan supports agriculture, ecosystems, and settlements across
neighboring countries including Kazakhstan and Uzbekistan.
| Water Resource | Approximate Amount |
|---|---|
| Lakes | ~1,900 |
| Glaciers | ~9,900 |
| Rivers and streams | 3,500+ |
| Total lake water volume | ~1,745 km³ |
Because of this concentration of high-mountain water resources, Kyrgyzstan functions as one of
the main freshwater storage regions of Central Asia. Changes in glacier size, snow cover, or
mountain climate therefore have important implications for water availability throughout the region.
Lake Clusters by Mountain Range
The distribution of lakes across Kyrgyzstan closely follows the structure of its mountain systems. Large tectonic lakes occupy major intermountain depressions, while smaller alpine lakes are scattered throughout glaciated valleys.
Major Lake Regions of Kyrgyzstan
| Region | Main Lakes | Mountain System | Typical Lake Types |
|---|---|---|---|
| Issyk-Kul Basin | Issyk-Kul | Tian Shan | Tectonic basin lake |
| Naryn Plateau | Son-Kul, Kol-Ukok | Inner Tian Shan | Plateau and glacial lakes |
| At-Bashy Basin | Chatyr-Kul | At-Bashy Range | High-altitude basin lake |
| Terskey Ala-Too | Ala-Kul | Tian Shan | Glacial alpine lakes |
| Central Tian Shan | Petrov Lake, Merzbacher Lake | Ak-Shyyrak Massif | Glacial and ice-dammed lakes |
| Chatkal Mountains | Sary-Chelek | Western Tian Shan | Landslide-dammed lakes |
| Pamir-Alay | Tulpar-Kol, Kulun | Pamir-Alay | High-mountain glacial lakes |
Together these lake regions illustrate how Kyrgyzstan’s lakes are closely connected to its mountainous terrain. From the vast tectonic basin of Issyk-Kul to small glacial lakes high in the Tian Shan, the country’s lakes form a diverse network shaped by geology, climate, and mountain hydrology.
Mountain Lakes of Central Asia
Kyrgyzstan is not the only country in Central Asia with mountain lakes, but its lake
distribution is unusual because most lakes are located in high mountain terrain.
Other countries of the region have different lake systems shaped by deserts, plains,
or large inland basins.
| Country | Approximate Number of Lakes | Main Lake Regions |
|---|---|---|
| Kyrgyzstan | ~1,900 | Tian Shan and Pamir-Alay mountains |
| Kazakhstan | ~48,000 | Northern steppe lakes, Balkhash basin |
| Tajikistan | ~1,300 | Pamir mountains |
| Uzbekistan | Relatively few natural lakes | Mostly reservoirs and remnants of the Aral basin |
Compared with its neighbors, Kyrgyzstan stands out for the density of high-altitude
mountain lakes concentrated in the Tian Shan range.
Largest Lakes in Central Asia
Central Asia contains several very large inland lakes and inland seas.
While Kyrgyzstan’s Issyk-Kul is the largest lake within the country,
other countries in the region contain much larger basins.
| Lake | Country / Region | Surface Area (km²) | Notes |
|---|---|---|---|
| Caspian Sea | Kazakhstan, Russia, Azerbaijan, Iran, Turkmenistan | ~371,000 | World’s largest inland water body |
| Lake Balkhash | Kazakhstan | ~16,400 | Large endorheic lake with both fresh and saline sections |
| Issyk-Kul | Kyrgyzstan | 6,236 | Largest lake in Kyrgyzstan |
| Aral Sea | Kazakhstan / Uzbekistan | Rapidly shrinking | Formerly one of the largest lakes in the world |
