Isinga (Russian: Исинга[2] or Исингинское)[3] is a fresh water body in the Yeravninsky District, Buryatia, Russia.

[3] There are vestiges of ancient human settlements on the banks of the Isinga dating back to 4-5 thousand years ago.

Archaeological excavations were carried out in 1972 at the sites of ancient settlements, providing a wealth of data in the Isinga area.

The Kholoy, a small, shallow tributary of the Vitim River, flows from the eastern shore of Isinga lake.

When the water levels are high the Yeravna lakes further south are connected with each other and the northern ones by intermittent channels.
