Some results of scenario calculations of hydrodynamics and the propagation of passive impurities in the lake are presented. We are talking about hypothetical scenarios for the development of lake pollution processes during one summer tourist season. Depending on the chosen scenario, sources of impurities are specified in certain places on the shores of the lake. This simulates the location of tourist sites. To increase the generality, the so-called climatic scenarios of atmospheric influences are considered, when data on wind fields and their operational characteristics reflect typical weather conditions in the region. The results of calculations in different scenarios are compared. Their analysis indicates that the functioning of tourism facilities should be regulated taking into account the characteristic features of the lake.
