The results of structural hydrophysical investigations at the Pleshcheyevo Lake are presented. There were at first revealed on the base of the data of direct measurements the distributions of parameters of current velocity and of water composition in lake. The theoretical distribution of current velocity with taken in to account the influence of internal wave, circulation and intrusion was verified. The submerged jet of the river water inflow in lake was discovered. There were obtained the measured and theoretical distributions of the total solids in jet. The quality corresponding between the obtained results and the materials of publications on the influence of currents on the biosphere of lake was established.
