on the Irtysh downstream from the Zaysan, the lake has risen 6 m (20 ft) above its natural level. As the result, the area of lake essentially increased (nearly doubled: from about 1,800 km² to 3,500 km², or even to 5,000 km²), thus, in some sources the lake is indicated as part of an artificial reservoir.

period with a likely age in excess of 66 million years old (most probably around 70 million years), although its exact age is controversial and labelled with some uncertainty. A direct indication of the Lake Zaysan's age is hard to find, although some geological studies of the Zaysan Basin have been reviewed. Artificial reservoirs cover large surrounding areas. Modern geological analysis of the entire field, apparently, supports an exceptionally old age for Lake Zaysan.

even proposed the annexation of the Lake Zaysan region, but this project was forestalled by Chinese successes. Concerns were raised in Russia (1759) about the (theoretical) possibility of a Chinese fleet sailing from Lake Zaysan down the Irtysh and into Western Siberia. A Russian expedition visited Lake Zaysan in 1764, and concluded that such a riverine invasion would not be likely. Nonetheless, a chain of Russian pickets was established on the Bukhtarma River, north of Lake Zaysan. Thus the border between the two empires in the Irtysh basin became roughly delineated, with a (sparse) chain of guard posts on both sides. The situation on the Zaysan in the mid-19th century is described in a report by A.Abramof (1865). Even though the Zaysan region was recognized by both parties as part of the Qing Empire, it had been annually used by fishing expeditions sent by the Siberian Cossack Host. These summer expeditions started in 1803, and in 1822-25 their range was expanded through the entire Lake Zaysan and to the mouth of the Black Irtysh. Through the mid-19th century, the Qing presence on the upper Irtysh was mostly limited to the annual visit of the Qing ''
