At the beginning of the XX century N. M. Yadrintsev came to the conclusion that the area of the lakes of Western Siberia is under continuous desiccation. V. V. Dokuchaev and his student G. I. Tanfilev prove that the water level in these lakes undergoes periodic fluctuations. And no shrinkage no. In our work we will try on the example Petukhovskoe soda lake, as the most studied in geological terms, to test this theory.
on the Basis of relevance, the aim of our work was to monitor Petukhovskoe soda lake to change the level of the brine.
