The fluctuations of the Baikal level in different periods of the Late Neopleistocene and Holocene are examined on the base of studies of subaerial cuts near the coastal edge on the low relief marks. It was found that in the Eemian Interglacial the Baikal level was close to the contemporary one. During the Murukta, Karga and Sartan period it was lower. That means the Baikal terraces of the Late Neopleistocene are under water now. The Early Holocene on the edge of the Boreal-Atlantic shows the lake-level rise up to the present mark. In the Middle and Late Holocene numerous level changes were registered. High marks didn't exceed 2.5 m in comparison to the existing level. The lake Baikal had higher level in 4800–4600 BP, 3700–3600 BP and approx. 2000 BP. The considerable level lowering (not less than 1–1,5 m) was registered in the Late Atlantic, approx. 5500–4800 BP.
