From November 1979 to June 1981, maser emission sources located in star formation regions were observed in the 1.35-cm lines of the water vapor molecule, using the 22-m radio telescope of the Pushchino Radio Astronomy Station, Lebedev Physics Institute. The data obtained for four sources, NGC 2071 (G205.1-14.1), W44C, W75N, and Cep A, are described in detail. All these objects display substantial variations in their overall H2O line profile as well as in the flux and radial velocity of individual features within the profile. The evolutionary status and dynamics of the maser sources are discussed.
