The intensive drainage works conducted a few centuries ago in Poland contributed to a significant depletion of the hydrographic network. Currently, there are more and more frequent problems with water stress and the introduction of a programme aiming at the retention development, i.e. through the construction of artificial reservoirs or damming up natural lakes. ; The paper presents the reconstruction of the morphometry of the non-existent Krokowo lake. It was found that the reservoir with the surface area of 58 ha and volume of 2.6 million m3 disappeared as a result of the anthropogenic impact. In the light of an increase in the retention possibilities in Poland, the restoration of natural lakes to their original condition seems to be an interesting approach. Renaturalisation of these environmental elements in the context of the balance components' improvement seems to be more justified that the creation of new (artificial) components.
