The joint efforts of several research units have been directed towards four levels in the ecosystems of lake reservoirs: the physicochemical environment, the plants, the bottom animals and zooplankton, and the fish. To get a comprehensive picture of the effects of the lake transformations, information from different lake reservoirs must be compiled, and the aim of the present survey is to compile information from some recent Swedish studies. The overall effect of the transformations is a decrease in the production capacity and a simplification of the ecosystems of lake reservoirs. Fishing can be maintained, if based mainly on the production in the pelagic block of the ecosystem.
