Estimation of the human activity impact on global warming is a very important goal nowadays. The main reason for planet temperatures rising is an increase in the concentration of greenhouse gases in the atmosphere. The main greenhouse gases are carbon dioxide and methane. The influence of the carbon dioxide has been investigated for a long time, while much less attention has been paid to the methane in this matter, however, more and more scientific articles have recently appeared on the topic of anthropogenic methane cycles and its emission into the atmosphere. The most significant anthropogenic sources of methane is waste fields, cattle pastures, rice areas, etc. One of the less obvious, but a significant source of the methane is artificial reservoirs. In order to more accurately assess methane emissions from reservoirs, it is necessary to study processes connected with methane fates in the aquatic ecosystems. For this problem, the Mozhaisk reservoir was chosen. This is a well-studied, small size, valley reservoir, where the study of methane fluxes has been carried out for 6 years, since 2015. Also, the Mozhaisk reservoir used as an object for testing the “LAKE” mathematical model. This one-dimension, hydrodynamics model can helps in estimation of the emission of methane into the atmosphere from the reservoirs surface.
