The results of a comprehensive geological and geophysical study of the Suzdal Lakes of St. Petersburg in 2019 are discussed. The objectives of this work were the preparation of the landscape basis for the subsequent assessment of the ecological state of these reservoirs and the development of a methodology for the comprehensive study of small lakes by geophysical methods. The following methods were used: sonar, acoustic profiling, side-scan location, georadar (GPR), electrical resistivity tomography and geological sampling. GPR and side-scan location proved to be the most effective for assessment section of loose deposits and distribution of the surface sediments and identification of technogenic objects. Maps the lakes bottom relief, lithological maps, maps of the location of technogenic objects on the lake bottom were prepared. Proposals are made for the most efficient integration of geophysical methods for creating landscape maps as the basis for environmental research.
