For fishery assessment of up-to-date state of three water storage reservoirs in the northern part of the Moscow area, classical methods of hydrobiological and ichthyological investigations were used, as well as echolocation and fish-farming plane-tables for calculation of growth possibilities of fish communities representatives. The low depths (average between 2 and 2.5 m) of the Yakhromskoe and Velevskoe water storage reservoirs create favorable conditions for intensive development of aquatic plants, they show greater similarities of ichthyofauna but the low growth rate, of the bream (Abramis brama) as the main object at the amateurish fishing. The Zhestylevskoe water storage reservoir, having the greatest area and depth (average 6 m depth) and the weed filling less than 5%, shows the bream growth rate higher than that one of the 2 other water bodies. The normative-legal rules of the Russian Federation permit to register officially fish cultural and fishing areas at water storage reservoirs of more than 100 hectare what allows to determine ways of their subsequent stable exploitation. On the example of the Yakhromskoe, Zhestylevskoe and Velevskoe water storage reservoirs , algorithms of reservoirs transference from one state into another one have been given with a view to use them intensively.
