Barsakelmes Lake is a small, saline lake located between the Northern and Western Seas of the former unified Aral Sea. It is the last remainder of the Eastern basin of the former South Aral Sea.

Around the 2010s, Barsakelmes Lake split from the South Aral Sea. It is occasionally fed by the North Aral Sea after heavy rain or snowmelt.

By August 2024, the lake was almost completely dry. Satellite images at the time showed a greatly reduced area (~150 km²) and a brown discoloration, indicating shallow water and the possiblity for the lake to completely disappear in the next couple of years.
