The influence of drainage systems to the hydrological regime of receiving rivers is analyzed, and the most significant factors influencing river runoff are presented. A set of measures aimed at preserving small and medium-sized rivers during the restoration and reconstruction of drainage systems is proposed.  Particular attention is paid to the environmental aspects of land reclamation as an important component of planning and implementation of drainage  works, which should contribute to maintaining the natural balance and preventing the depletion of water resources.
