By reclamative network of drainage basin water is pumped by stations in the complex appointment water bodies, the reservoir. On reclaimed areas dry-dumping system is a kind of collector of contamination. In autumn water flows in reservoirs and ponds used for fishery purposes due to its gravity or is pumped by the stations. Autumn filling provides a sufficient amount of water and prevents overgrowing in reservoirs as well. Actually water natural function of self-purification reduces the contents of contaminations in water bodies.ф
