Water reservoirs, as an element of small water retention, play an essential role in increasing the quantity of retained water as well as in extension of time and paths of its circulation in an agricultural landscape. One of possible ways to realize this aim is utilization of small reservoirs as a „water store" of drainage outflows. The method of ponds land reclamation importance valorization is presented in this paper. Following factors were considered as the criteria of an evaluation: reservoir surface area, its morphology, connection with hydrographic net, character of water structures (e.g. dams) and periodicity of water reservoir occurrence. The results of our research unambiguously indicated considerable drainage usefulness of water reservoirs to foregoing introduced aims. Drainage outflow water retention in water reservoirs will enable 100-150% increase of retained water quantity. It is a vital work, for the studied catchment area is situated in a region of the largest water deficits in Poland.
