In the article assessment of main members of the water balance equation is fulfilled total evaporation and infiltration for the conditions of the Vologda region. The work is fulfilled by means of a linear-correlation model for the first time for assessment of the infiltration layer into ground water for the investigated area. It is stated that in the linear-correlation model the legality of usage of linear dependence of the river flow from atmospheric precipitation is brought into the foreground as well as physical substantiality of the model from the point of view of existing hydrological regularities on the basis of the genetic theory of runoff. This circumstance is attractive for the practical usage of the linear-correlation model. As a result of researches it is established that the values of the total evaporation layers calculated according to the linear-correlation model were less by approximately 1,5 times. This circumstance is explained by inclusion of the infiltration layer into the total evaporation. Maximal values of the total evaporation reached the values 333 mm (r. Sukhona town Totjma), 296 mm (r.Sukhona v. Rabanjga). With these values of evaporation layers infiltration layers are minimal and were 37 and 14 mm.
