The lake stretches for more than 100 kilometres, while its width ranges from 22 to 48 kilometres. Its average depth is 4 to 8 metres, with a maximum depth of around 15 metres. Many rivers flow into the lake, the largest being the Black Irtysh, while the Irtysh River flows out of it.

According to several studies, Lake Zaysan may be among the oldest lakes on Earth. Some estimates suggest an age of tens of millions of years, making it an important geological site.

The lake is rich in fish species, including pike-perch, pike, carp, crucian carp and bream. Its shores are covered with reeds and aquatic vegetation, providing habitat for many bird species and migratory birds.

Since ancient times, the lake area was inhabited and used by nomadic peoples. Later it became part of important trade routes connecting neighbouring regions.
