The lake water is fresh, with a low transparency of about 2.5 m due to plankton and suspended sediments caused by the river flow. Water currents are weak 5-9 cm/s; generally induced by wind, so stop when it ceases. However, during the spring flood, there is a constant surface current from north to south.

Because of the shallow depth, the lake quickly warms and cools. Water temperature reaches 25-26 C in July. The lakes freeze in late November to early December, and they
