The paper presents an attempt to describe water exchange in Lake Baikal proceeding from interpretation of tracer (freon-12) contents and temperature of water. Disturbance of the metastable equilibrium of the upper water layer in the cold season at reverse stratification is suggested as a controlling mechanism of deep-water renewal. A system of one-dimensional equations of substance (for the tracer) and heat budget is proposed. The solution to an inverse problem for turbulence coefficients and water exchange flows shows a considerable role of turbulence in the upper water column. A function is proposed to describe the depth-dependent distribution of downwelling flows in the upper layer of water.
