Previously, a hypothesis was put forward about a change in the degree of hydrophicity of lakes under the influence of fluctuations in the level. At the same time, the direct abiotic factors leading to ecosystem changes are the illumination of the soil and the level of its wind resuspending. At the same time, there were no empirical correlations between these indicators in relation to the lakes of the Ivano-Arachley system. In this work, based on the study of the lakes of the Ivano-Arakhley system, during the period of extremely low water content, a correlation is shown between the depth of macrophyte growth and the transparency of water at a damage of 0.96 (p=0.002). Factor analysis by the method of principal components showed a high positive relationship with the morphometric parameters of the ecosystem and the degree of openness of the reservoir. The relationship between the depth of vegetation distribution, water transparency, the ratio of depth, lake area expressed in terms of the coefficient of openness must be taken into account when planning activities on lakes that can affect vegetation or water transparency.
