Overview

Azerbaijan contains a large number of small natural inland lakes scattered across its varied landscape. There are roughly 450 such lakes, almost all modest in area and volume. This compilation treats the natural bodies commonly called lakes in the country and does not include engineered waterbodies or the adjacent inland sea on the east.

For clarity: this article concerns a general list of lakes in Azerbaijan, excluding artificial lakes such as reservoirs and barrages. The Caspian Sea, while the planet's largest enclosed waterbody by area and volume, and frequently treated as a lake, is not included here; see Caspian Sea for that subject and its status as the world's largest lake by those measures.

Formation and types

Lakes in Azerbaijan arise from a range of geological and hydrological processes. Common origins include tectonic depressions, basins formed and blocked by landslides, river processes such as oxbow formation and backwater ponds, coastal lagoons, and high‑altitude basins left by retreating glaciers (often described as glacial lakes). Many lakes are fresh (fresh water), while others have elevated salinity and are classed as salt lakes.

Geographic distribution and notable examples

Natural lakes appear in three principal zones: the mountain belts of the Greater and Lesser Caucasus, where glacial and landslide lakes occur; the midland and lowland plains, where riverine and oxbow lakes form; and the coastal strips, where lagoons and saline basins are found. Mountainous areas often host small, clear alpine lakes shaped by both mountain processes and past glaciation.

Characteristics and uses

Although most Azerbaijani lakes are small, they have value beyond size. They serve as freshwater resources for local communities and livestock, provide habitat for fish and wetland species, and are important stopover sites for migratory birds. Many lakes also support seasonal grazing, artisanal fishing, and local recreation. The larger natural lakes—only a handful exceed ten square kilometres—often have distinct ecological roles in their basins.

Conservation, threats and management

Lakes and associated wetlands face pressures from water extraction, land‑use change, pollution, and climate variability. Conserving these systems often involves a mix of national protection measures, landscape planning, and participation in international frameworks. Some lake and wetland areas are recognized for their biodiversity and are subject to targeted management to maintain habitat quality and sustain traditional uses.

Distinctions and notable facts

  • Natural lakes are treated separately from engineered reservoirs and from the Caspian Sea, even though the sea functions as a major regional waterbody (Caspian Sea).
  • Formation mechanisms cited in the geological literature include tectonic, landslide, riverine (including oxbow), lagoons, and glacial processes.
  • Most lakes are freshwater, though saline basins occur near coasts and in closed depressions.

Readers seeking a compiled inventory or regional lists can consult specialized geographic and environmental resources for mapped names and locations; this article provides a structured introduction to the natural lakes of Azerbaijan and explains how they are classified, where they occur, and why they matter.
